ICD-10-CM for right shoulder pain is M25.511, “Pain in right shoulder.” Use this code when the record supports right shoulder pain and another established diagnosis does not better explain the encounter. M25.512 is left shoulder pain. You need both codes for bilateral shoulder pain if you are using symptom codes.
Coding for shoulder pain may get complicated if the record indicates that there could be a tear, stiffness, an injury, or pain radiating to the arm. Each piece of information makes a difference in coding. This article will discuss the difference using code description, documentation, and claim verification.
Quick Reference: Shoulder Pain and Related ICD-10-CM Codes
The table separates pain codes from diagnosed conditions. Choose the code supported by the provider’s assessment, the complete record, and applicable coding instructions.
| Code | Description | Key distinction |
|---|---|---|
| M25.511 | Pain in right shoulder | Identifies the right shoulder pain symptom |
| M25.512 | Pain in left shoulder | Identifies the left shoulder pain symptom |
| M25.519 | Pain in unspecified shoulder | The record does not establish the affected side |
| M25.611 | Stiffness of right shoulder, not elsewhere classified | Describes stiffness rather than pain |
| M75.01 | Adhesive capsulitis of right shoulder | Use for a documented frozen shoulder diagnosis |
| M75.51 | Bursitis of right shoulder | Identifies documented shoulder bursitis |
| M75.41 | Impingement syndrome of right shoulder | Right-sided impingement diagnosis |
| M75.21 | Bicipital tendinitis, right shoulder | Identifies the specified tendon condition |
| M75.31 | Calcific tendinitis of right shoulder | Requires the documented calcific condition |
| M75.101 | Unspecified rotator cuff tear or rupture of right shoulder, not specified as traumatic | Tear extent is unspecified |
| M75.111 | Incomplete rotator cuff tear or rupture of right shoulder, not specified as traumatic | Identifies an incomplete tear |
| M75.121 | Complete rotator cuff tear or rupture of right shoulder, not specified as traumatic | Identifies a complete tear |
| M19.011 | Primary osteoarthritis, right shoulder | Requires primary osteoarthritis documentation |
| M79.601 | Pain in right arm | Describes arm pain rather than shoulder joint pain |
| M79.621 | Pain in right upper arm | Identifies the upper-arm location |
| G89.29 | Other chronic pain | Adds pain-type information when documentation and guidelines support it |
The rotator cuff descriptions include the qualification “not specified as traumatic.” A documented traumatic rotator cuff injury requires review of the injury classification. These codes are not interchangeable treatments for the same complaint.
The Meaning and Limits of M25.511
M25.511 indicates the location and laterality of a symptom. It does not indicate the cause of the pain; that is, it does not identify the exact tendon, bursa, ligament, bone, or joint structure causing the pain. Neither does it denote the degree of pain or if it is an acute or chronic one.
The classification system of the code is simple. M25 denotes other joint disorders. M25.5 specifies joint pain, while M25.51 indicates shoulder pain. M25.511 is used to specify right shoulder pain.
M25.51 is a parent subcategory and thus is not a billable code; it requires addition of digits to complete it. M25.511 is complete and does not take injury encounter extension. Addition of an A, D, or S to it makes the code invalid.
“Billable” implies that the code contains sufficient information for diagnosis coding. However, the insurer does not have to cover any services associated with the use of the code, but rather depends on coverage, medical necessity, benefits, authorization, and documentation of the service provided.
In summary, as far as a patient is concerned, the only thing that the code indicates is that there is right shoulder pain.
Selecting a Pain Code vs. Diagnosis
The primary issue in coding is whether the provider has determined the underlying condition behind the shoulder problem. Analyze the assessment along with any other documentation. There is no automatic correlation between chief complaint, a finding on physical exam, and diagnostic impression.
Documented symptom is a valid diagnosis for coding purposes
The code M25.511 is applicable when the provider diagnoses the patient with right shoulder pain and does not determine any underlying condition. There is no need to interpret the symptom as a specific structural condition simply because imaging, therapy, or referral to a specialist is ordered.
For instance, in the assessment, it is noted: “Right shoulder pain; undetermined cause.” This information justifies the use of symptom codes. A plan of diagnostic workup suggesting probable rotator cuff disease is not a separate determination of tear.
Unspecified cause and unspecified side are two separate issues. M25.511 accurately describes a known side and localization of the shoulder even in the case of undetermined cause. M25.519 implies that shoulder side is unspecified.
Outpatient uncertainty needs to stay uncertainty
For outpatient professional services, never report “suspected,” “probable,” “rule out,” or like uncertain diagnoses as confirmed conditions. Report only what is documented – symptoms, findings, or reason for the encounter – as high a certainty as is possible.
“Possible right rotator cuff tear” in an office note does not automatically justify M75.111 or M75.121. M25.511 could be considered if right shoulder pain is supported by the provider’s established assessment.
Rules for inpatient hospital cases with an uncertain diagnosis are different. Application of an inpatient rule to an outpatient claim results in an unsupported diagnosis.
Condition confirmation alters the code selection process
Where the provider confirms the presence of right shoulder bursitis, then the condition should be coded using M75.51. For adhesive capsulitis, the diagnosis should be coded using M75.01. The clinical documentation should clearly support the selected condition.
An MRI should not always be made the prerequisite for coding purposes. There are conditions that can be clinically diagnosed. In addition, an imaging-based diagnosis should never be translated on its own to the physician’s diagnosis where the particular encounter requires the physician’s diagnosis. Diagnostic test encounters have their own guidelines.
Chronic pain usually related to a confirmed condition is rarely coded separately, unless the classification advises otherwise. Symptoms which are not typically related to the condition may be reportable. Addition of M25.511 to all shoulder diagnoses results to redundancy rather than specificity.
Laterality: Right, Left, Bilateral, and Unspecified
Laterality should agree across the assessment, order, procedure documentation, and claim. A right-sided diagnosis paired with left-sided procedure documentation requires clarification.
| Documented finding | Symptom-code approach |
|---|---|
| Right shoulder pain | M25.511 |
| Left shoulder pain | M25.512 |
| Pain in both shoulders | M25.511 and M25.512 |
| Shoulder pain with no supported side | M25.519 |
There is no bilateral code in the M25.51 category. M25.519 is not a bilateral equivalent, and M25.50 is for pain of an unspecified joint and not for pain of both shoulders.
Furthermore, each shoulder requires separate diagnosis. The patient can have a confirmed right shoulder bursitis along with the undiagnosed left shoulder pain. In such a case, the record may justify the use of M75.51 for the right shoulder and M25.512 for the left one rather than using two generic codes.
In case the provider fails to provide information on laterality, the guidelines allow using other clinicians’ records to specify the laterality. However, that provision does not allow the coder to make conclusions about the condition based on the record. Contradictory information regarding right versus left should be questioned rather than being resolved with the choice of more convenient code.
In case the record does not provide any information regarding laterality and clarification cannot be attained, the unspecified-side code may present the information precisely enough.
Shoulder Pain, Arm Pain, and Stiffness Are Not One and the Same
Not all instances of pain in the area of the shoulder necessarily involve the shoulder joint. M79.601 denotes right arm pain; M79.621 denotes right upper-arm pain. Neither code should be substituted for M25.511 simply based on the patient’s gesture toward the affected extremity.
The specific documentation terminology used must be considered. “Right shoulder pain radiating into the arm” is not necessarily a description of two pain complaints. Specific symptoms related to the arm must be documented and reviewed against the appropriate coding guidelines.
Stiffness must also be taken into account. Right shoulder stiffness (not elsewhere classified) is coded with M25.611; right elbow pain is M25.521. Limited range of movement alone does not establish adhesive capsulitis.
Referred pain is yet another differentiating factor. In cases where the provider has established another medical diagnosis as the cause for the symptoms, code the appropriate codes based upon the provider’s documentation and the coding guidelines. The coder cannot independently make a diagnosis of radiculopathy based on tingling or radiation into the arm.
Excluding Notes Without Overgeneralization in Reading
Selection of codes is done with help of the Alphabetic Index and Tabular List. Instructions of the parent category may be applicable to the child codes, although they do not prominently appear in short code look up.
There are two special types of exclusions that are useful in coding shoulders: Excludes1 and Excludes2. These have different uses and should not be treated as interchangeable claim edits.
Excludes1 and traumatic rotator cuff tears
For M75.1 rotator cuff category, there is Excludes1 for traumatic rotator cuff tears in S46.01-. You cannot use both of them to describe one tear.
An Excludes1 note usually means the exclusion cannot be used together with the code having the note. There is officially recognized exception if the two conditions are unrelated. The lack of clarity here needs provider input.
The basic rule here is finding out the lesion that has been documented and whether it is traumatic. Saying that there is no way the two families of codes can ever appear on the same claim misses the exception. At the same time, this does not allow coding the lesion twice.
Excludes2 and specific limb symptoms
The code M25.5 has Excludes2 instructions for limb as well as some other pain sites. Excludes2 means that the condition in question is not part of the code and can be coded with it if it occurs in the same case.
This is why M25.511 and M79.601 are not automatic substitutes nor an automatic couple. It needs to be determined whether there are two reportable symptoms or a single symptom with radiation in the record.
In addition, M25 codes have an Excludes2 for calcification of the shoulder joint which is classified to M75.3. The Excludes2 in conjunction with the physician’s diagnosis and the routine symptom guideline must be considered.
An Excludes2 permits but does not mandate a combination.
Injury or Trauma Encounters with Characters
Falls, lifting mechanisms, or sports are factors that will affect the assessment but do not make up an injury on their own. Code the injury that is found. If a right shoulder pain was all that was found, then don’t make something up like a sprain, fracture, dislocation, or tendon tear.
The injury diagnosis requires the use of the correct injury code including what part of the body was injured and laterality. A rotator cuff muscle/tendon injury, shoulder girdle sprain, or shoulder dislocation will not have just one code called right shoulder injury.
Some injury codes need to have a seventh character. These characters mean:
- A: Active treatment for the injury.
- D: Routine treatment for healing/recovery from the injury.
- S: Residual effect/sequela from the injury.
Treatment phase determines the character selection, not the number of visits. Injury treatment may involve using the injury code with the proper character instead of a pain or aftercare code.
Reporting requirements of external causes may vary. This should be considered separately from the injury diagnosis. The external cause code gives the circumstances, but does not take the place of the code for the condition.
Clarify Ambiguous Shoulder Coding
Can’t tell if the medical record indicates the need for M25.511 or an injury-specific code? Ask for help with coding to ensure clarity of documentation and laterality.
Acute & Chronic Pain: Appropriate Use of G89
Although M25.511 describes the site and side of the pain, it fails to distinguish whether the pain is acute or chronic. It is applicable for both cases depending on the documentation of the provider supporting symptom-based coding.
The presence of an acute pain description does not imply that there was any sort of trauma. In the same way, chronic shoulder pain cannot be diagnosed as arthritis, tendon tear, or chronic pain syndrome as each of these needs different documented findings.
G89.29 or other chronic pain could be coded where there is chronic pain documented along with the coding guidelines supporting the code. It should not be coded simply based on the presence of recurrent complaints and visitations. For patients needing coordinated care for documented chronic conditions, Chronic Care Management Services may apply separately from these.
Sequencing depends on the nature of the encounter
In the case of an encounter meant specifically for pain control or pain management, G89 will be first coded. A code indicating the location of the pain is used to indicate the specific site.
In the case of an encounter not meant for the purposes stated above, but no definitive diagnosis is made, the code for the site of the pain comes first, followed by the relevant G89 code where it adds any useful information.
If the condition is a known one, do not use G89.29. The instruction limits the coding of G89 where there is a definitive diagnosis, unless in the case of pain control or pain management.
Chronic pain syndrome is represented by the code G89.4, which needs that definite diagnosis. Chronic symptoms, pain or referral to pain management does not make up the diagnosis.
Pain after procedure requires its own evaluation
Expected pain following surgery, pain after procedure evaluated separately, injury rehabilitation, surgical aftercare, and complications recorded are different code scenarios. One should never use M25.511 as a catch-all code for these scenarios.
Check the relationship to the procedure, the goal of the treatment and any complication evaluation. Follow the proper instructions for pain after procedure, surgical aftercare, injuries or complications. The pain complaint alone is not a proof of surgical complication.
Documentation Supporting the Chosen Code
An effective shoulder note provides information about what is known, what is unknown, and what services have been rendered. Ideally, this documentation should give the coder a clear idea about the clinician’s assessment without requiring him/her to make a diagnosis based on scattered pieces of information.
Depending on the case, imaging is not necessary for the code M25.511. There is no one-size-fits-all list of mandatory examinations for every shoulder pain consultation.
Document the location and clinical assessment
Indicate the affected shoulder clearly. Separate symptoms related to the shoulder joint, upper arm, neck or a local area from the general shoulder pain if the patient’s examination justifies this differentiation.
Document the diagnosed condition or indicate that the cause of the problem is unknown. Do not let your template dictate a certain degree of certainty to you. In case of suspected conditions, keep this uncertainty in your report.
Among other examination findings that may be important for the coding are tenderness, restriction of movement, muscle strength tests, swelling, or pain when doing certain movements. However, positive special test results cannot be treated as established diagnoses by coders.
Relate the problem to the service
Describe the functional deficit and the rationale for the service. An imaging request, referral for therapy, or administration of an injection must be justified by the true problem and rationale, not simply a diagnosis code plugged into the claims field.
With respect to physical therapy, documentation must provide information about impairments, functional limitations, goals, and skilled interventions that make up the treatment plan. The code M25.511 refers to a symptom only, and not all of those pieces of information.
The level of pain and its effect on function may be important clinical information without altering the M25.511 code. There is no code M25.511 for mild, moderate, or severe pain.
Documentation framework example
The following is an example of a framework, not the documentation to put in the patient’s record:
Assessment: Right shoulder pain that does not have a known cause. The pain is present with reaching above the head and prevents dressing. There is noted tenderness and painful movement on examination. A specific tendonitis, arthritis or trauma has not been diagnosed. Plan: Document the evaluation and services provided.
The code M25.511 could document that assessment. The actual note needs to describe the actual assessment, treatment and diagnostic decision made.
In the case where there is a conflict between the referral, the exam, and the assessment regarding which side or which condition is being diagnosed, it should be clarified.
Reconcile discrepancies through a neutral query
The query should state the problem in the documentation and provide the clinical data without leading the provider to make a more profitable diagnosis. A neutral query for a side discrepancy might be, “The assessment states the right shoulder, and the procedure note states the left shoulder. Please clarify which side is affected and treated.”
When the problem is the diagnosis discrepancy, state the conflicting diagnoses and ask the provider to clarify the diagnosis based on the assessed condition. Do not ask the provider to confirm the tear just because the payer has the code on its coverages list.
The answer to the query needs to be part of the proper documentation process. It is not enough to rely on a coder’s assumption, a default in a template, or an undocumented discussion.
Practice Coding Examples
These are fictional scenarios that serve to provide insight into real-world coding considerations. They are neither representations of actual patients nor reimbursement results. It is assumed that the full medical chart justifies the findings presented and there is no overriding instruction regarding coding.
Scenario 1: Shoulder pain on the right side with possible rotator cuff tear
There is a note in the patient’s medical file with regard to right shoulder pain, as well as a rotator cuff tear possibility. The treatment plan includes diagnosis, but there is no confirmed evidence of a tear.
Coding strategy: M25.511 might be considered. Do not choose code for complete or incomplete tear based on the differential diagnosis. The critical point is not the test used, but whether or not there is confirmation of a tear.
Scenario 2: Bilateral shoulder pain with different etiologies
The physician diagnoses bursitis in the right shoulder while documenting pain in the left shoulder with no known cause. Both the diagnoses are impacting the treatment provided.
Coding strategy: M75.51 and M25.512 might code for the conditions documented. Do not include the right shoulder pain automatically if it is part of the bursitis. Bilateral conditions do not necessarily need to have identical diagnosis codes, and M25.519 cannot code for this case.
Scenario 3: Fall without injury
A patient with a history of right shoulder pain after a fall is seen in an outpatient facility. The provider examines the patient and does not find any fractures, dislocations, sprains, and tears.
Coding strategy: Coding should only include the documented condition, if there is one. M25.511 can possibly be coded if the right shoulder pain is documented. Consider the external causes of the injury separately. The injury mechanism alone does not allow the coder to assign an injury diagnosis that has not been established by the provider.
Scenario 4: Documented case of incomplete rotator cuff tear
The assessment indicates an incomplete tear of right rotator cuff, not documented as being caused by any trauma. This scenario deals with this condition.
Coding strategy: M75.111 will be selected to code the specified tear. Selecting M75.121 will be incorrect, since it implies complete tear. The use of M75.101 will disregard documented information. M25.511 will generally not need to be coded additionally for pain associated routinely with this condition. Clarify any conflicts in terms of the presence or absence of trauma in the record, rather than select the preferred code range.
Scenario 5: Chronic pain management with no diagnosis of the cause
The provider documents chronic right shoulder pain; the encounter is for pain management. No condition of the shoulder is documented.
Coding strategy: The first-listed code could be G89.29, while M25.511 will indicate the site of pain. These codes follow the rules of pain management. Do not replace it by G89.4, unless there is a specific chronic pain syndrome diagnosis.
Scenario 6: Stiffness of the shoulder without documented pain
The assessment finds right shoulder stiffness, unspecified, without evidence of any condition causing this stiffness. The provider does not document shoulder pain as a reportable diagnosis.
Coding strategy: Consider M25.611, but not M25.511 just because of the common association between stiffness and shoulder pain. If the provider makes a diagnosis of adhesive capsulitis, contracture, or ankylosis, look at the proper code for this particular diagnosis. Reduced range of motion is not sufficient for making such a diagnosis.
Billing, Physical Therapy and Medical Necessity
There is a difference between diagnosis codes and procedure codes. The purpose of ICD-10-CM is to identify the diagnosis or reason for which the patient was treated, whereas CPT and HCPCS codes describe the services and equipment billed in the claim.
There is no CPT code “Right Shoulder Pain.” There are examination codes, imaging codes, exercise codes, injection codes, and surgery codes that will depend on the specific procedure done by the therapist. Practices requiring assistance with claims, documentation, and reimbursements will benefit from physical therapy billing services for accuracy in matching diagnosis with procedure codes.
Physical therapists may use M25.511 for reporting right shoulder pain, but the code does not fulfill the requirement for a plan of care, functional assessments, treatment goals, and documentation of skilled physical therapy. Impairments may be reported only when there is appropriate documentation of the impairment.
The procedure-specific modifiers also need to be reviewed separately. M25.511 does not fulfill the RT or LT requirement for the procedure performed. Also, reporting right and left shoulder pain codes does not mean that the procedure was bilateral.
Investigate the denial rather than changing the diagnosis reflexively
If a claim linked to M25.511 is denied, read the payer’s actual explanation. The issue may involve authorization, benefits, service documentation, diagnosis linkage, procedure edits, or a mismatch in laterality.
For example, a request for imaging documentation is not an invitation to replace shoulder pain with a suspected tear. A complete code can be accurate even when the submitted records do not support payment for a particular service.
Compare the assessment, billed service, authorization, and relevant coverage policy. Correct a diagnosis when the record supports the correction. Address a documentation or authorization issue through the appropriate process. Selecting a more severe diagnosis solely to obtain coverage is unsupported coding.
For an appeal, organize the evidence around the stated denial reason. A laterality issue calls for consistent side documentation. A medical-necessity request calls for the relevant findings, functional effects, and clinical rationale. A procedure-reporting issue calls for the service record and applicable reporting instructions.
This approach also helps distinguish a corrected claim from an appeal. The appropriate route depends on what was wrong or missing and the payer’s process. A different diagnosis code is useful only when it accurately represents the documented encounter; it cannot substitute for evidence supporting the service.
Common Shoulder Coding Errors and Better Decisions
Several errors come from treating a short description on a search result as a complete coding instruction. Verify the full descriptor and its place in the classification.
| Common error | Better decision |
|---|---|
| Submitting M25.51 | Select the complete code supported by laterality |
| Using M25.519 for bilateral pain | Report M25.511 and M25.512 when both symptoms are reportable |
| Using M25.50 for documented shoulder pain | Preserve the known joint and side |
| Calling M75.40 right shoulder impingement | M75.40 is unspecified-side impingement; M75.41 is right-sided |
| Calling M75.02 right shoulder bursitis | M75.02 is left adhesive capsulitis; M75.51 is right bursitis |
| Using M25.521 for shoulder stiffness | M25.521 is right elbow pain; assess whether M25.611 applies |
| Treating M75.111 as generic tendinitis | It describes an incomplete rotator cuff tear or rupture, not specified as traumatic |
| Adding pain to every confirmed condition | Apply the rules for routinely associated symptoms |
| Adding G89.29 without support | Check the pain documentation, encounter purpose, and G89 guidance |
A useful coding habit is to separate three checks: what the record establishes, what the classification instructs, and what the payer requires for the service. A problem in one area should not be “fixed” by inventing information in another.
Confirming Classification and Coding Claim Together
Use the official CDC/NCHS ICD-10-CM browser or classification documents to search for the diagnosis in the Alphabetical Index and verify it in the Tabular List. Review the parent category information, exclusions, required codes and sequencing guidance.
The ICD-10 classification is published by WHO, while CDC/NCHS produces the ICD-10-CM U.S. modification. U.S. coding guidelines are published by CMS and NCHS. A WHO general ICD-10 code lookup cannot be used as a replacement of the U.S. classification and guidelines for the ICD-10-CM coding claim.
Check the classification version applicable to the claim and the coding conventions applicable to its care setting. Review the payer’s requirements separately. The classification defines code meaning but not all issues related to the claim.
Quick Word to the Patients
M25.511 in an invoice or clinical document means pain in the right shoulder. It neither explains the reason for this condition nor recommends any treatment method. Any questions regarding the findings need to be addressed to your treating physician.
In case there is chest pain or breathing difficulties, dizziness or sweating along with the shoulder pain, you need to seek immediate medical help. Major injury, deformity or severe swelling of the shoulder joint needs prompt medical attention.
Frequently Asked Questions
What is the ICD-10 code for right shoulder pain?
M25.511 means “Pain in right shoulder.” It is a complete, billable ICD-10-CM code for the documented symptom. A specific established condition may require a different diagnosis code.
Which codes describe left and bilateral shoulder pain?
M25.512 describes left shoulder pain. When reportable pain affects both shoulders, assign M25.511 and M25.512. M25.519 describes an unspecified side, not bilateral pain.
Can M25.511 be used for chronic right shoulder pain?
Yes, when symptom coding is appropriate. G89.29 may add documented chronic-pain information when supported by the official guidelines. Sequencing depends on the encounter’s purpose. Chronic pain syndrome requires its own specific diagnosis.
Is M25.511 appropriate for a rotator cuff tear?
A confirmed tear generally requires a tear-specific code. Selection depends on the documented side, tear extent, and traumatic status. A suspected outpatient tear should not be coded as confirmed.
Strengthen Your Shoulder Claim Review
Have assistance in confirming that there is a connection between the diagnosis and the service and filling any documentation gaps in order to submit or review shoulder claims successfully.
Does M25.511 ensure reimbursement for imaging/physical therapy?
No. It will indicate the indicated reason for the treatment but the payment will be based on the treatment provided, medical necessity, insurance benefits, and payer rules. Being billable does not automatically mean it is covered.
