A patient comes to an orthopedic office with complaints of left shoulder pain that has been ongoing for several weeks. Upon examination and review of symptoms, the physician orders imaging of the shoulder. However, the evaluation fails to determine any specific underlying cause.
What diagnosis should be submitted for billing?
The correct ICD-10 left shoulder pain code is M25.512 when the documentation indicates left shoulder pain, and there was no other definitive diagnosis made at that particular encounter.
This question may appear to have an obvious answer; however, slight changes in the documentation will change the answer altogether. If there is right shoulder pain, then the reporting code should be something else. Other diagnoses like rotator cuff tear, adhesive capsulitis, and shoulder trauma may need a completely different diagnosis code.
From a physician’s, orthopedist’s, physical therapist’s, or biller’s standpoint, this will affect the reporting of the patient’s condition in their claims.

What Is the ICD 10 Code for Left Shoulder Pain?
Code M25.512 refers to shoulder pain in the left side. The code falls under category M25 Other joint disorder, not elsewhere classified and designates shoulder pain based on laterality.
Healthcare providers and medical coders usually employ M25.512 during an encounter where the issue is about shoulder pain in the left side and no specific diagnosis that describes why the patient was being treated is made.
For the 2027 fiscal year, which is between October 1, 2026, and September 30, 2027, M25.512 will be a valid and billable diagnosis code.
Shoulder Pain ICD-10-CM Code Chart for 2027
| ICD-10-CM code | Official description | Billable |
| M25.512 | Pain in left shoulder | Yes |
| M25.511 | Pain in right shoulder | Yes |
| M25.519 | Pain in unspecified shoulder | Yes |
| M25.51 | Pain in shoulder | No |
Code M25.51 acts as a parent category but is not an entire diagnosis code used for billing.
The three billable codes can help identify which shoulder was impacted. This will be preserved in the FY 2027 coding.
When Should Providers Use M25.512?
Think about an office visit where a patient complains of pain in the left shoulder when lifting the arm above the head. The patient has difficulty dressing and picking up items due to the pain.
The doctor checks on the movement, strength, and tenderness of the shoulder joint. It seems there is a musculoskeletal disorder in this case, but it cannot be determined what causes it in this visit.
The documentation includes the following:
Pain in the left shoulder; further evaluation needed.
In this case, it would most likely be appropriate to use M25.512 as the documented condition.
It is a code for the symptom that the doctor examined, not for the disease the doctor has not yet determined.
What M25.512 Does Not Tell the Payer
This code describes the location of the pain. This code does not describe:
- Why the shoulder hurts.
- If there is an injury behind the symptoms.
- The duration of the pain.
- If the patient has arthritis or a tendon condition.
- The severity of the pain.
A billing staff is not supposed to make any assumptions from this code regarding these clinical aspects.
Similarly, this code does not automatically cover all the imaging tests, injections, or treatments provided by the healthcare facility. There should be a reason for providing this treatment and the payer policy needs to cover it.
Right Shoulder Pain ICD 10: How Does It Differ From Left Shoulder Coding?
ICD-10-CM code system contains separate codes for right shoulder pain and left shoulder pain.
The code M25.511 is assigned to pain of the right shoulder, and the code M25.512 is assigned to pain of the left shoulder.
Despite the fact that codes are very similar with differences only in the last number, the choice of an incorrect code will cause discrepancy between medical record and claim.
For example, the provider will put right shoulder pain in the assessment, but the favorite in EHR diagnosis will remain M25.512 as the result of the previous visit.
Without taking laterality into account when coding the choice, the claim will become outdated in terms of the updated documentation.
Further clarification from the insurer will be required about the contradictory diagnosis and procedure documentation.
What if a Patient Has Pain in Both Shoulders?
There is no ICD-10-CM code for bilateral shoulder pain under M25.51.
When the pain in both shoulders is noted without any other specific diagnosis being more significant, the coder can code:
- M25.511: Pain in right shoulder
- M25.512: Pain in left shoulder
Both of these indicate the noted laterality.
M25.519 should never be used merely because bilateral pain exists.
What If the Provider Does Not Specify the Shoulder?
M25.519 signifies shoulder pain but it does not specify the shoulder.
The practitioner can code for shoulder pain under the assessment but cannot indicate which shoulder, left or right, is involved. If the documentation is not sufficiently clear to identify the shoulder involved, M25.519 can be used.
This notwithstanding, codes for conditions that are not specified should not take precedence over documentation.
When the documentation clearly states that the left shoulder is being discussed in the examination but does not indicate laterality in the assessment, the coding department should act accordingly and in compliance with documentation guidelines.
When Shoulder Pain Requires a More Specific Diagnosis Code
Not every patient with shoulder pain should receive M25.512.
Shoulder discomfort can accompany several conditions, including tendon disorders, fractures, arthritis, capsulitis, and other musculoskeletal problems.
The correct coding decision depends on what the provider establishes by the end of the encounter.
Rotator Cuff Conditions
Rotator cuff problems and diseases include pain, weakness, and trouble lifting the arm.
In case of a confirmed diagnosis of a rotator cuff tear by the doctor, then the encoder should check for the rotator cuff diagnosis code set instead of using the shoulder pain code.
The code might differentiate between the trauma-induced and non-trauma induced and may need further information like laterality and the nature of the injury.
A traumatic rotator cuff tear code could be under the S46 code set while a non-traumatic rotator cuff tear code could be under the M75 code set.
It is necessary to check both the provider’s diagnosis and the coding guide prior to assigning a code.
Adhesive Capsulitis
Adhesive capsulitis, also known as frozen shoulder, often results in pain accompanied by limited movement of the shoulder joint.
Should the doctor confirm adhesive capsulitis of the left shoulder, the appropriate ICD code would be M75.02.
The condition specifies the disease rather than the pain of the patient.
Shoulder Osteoarthritis
Osteoarthritis can result in shoulder pain and stiffness.
Shoulder osteoarthritis diagnosis by the physician should prompt evaluation of the proper arthritis coding, as to whether it is a primary, post-traumatic, or other arthritis.
An established diagnosis of arthritis can better describe the encounter than a code for shoulder pain alone.
Traumatic Shoulder Injuries
Injuries such as fractures, dislocations, sprains, or others may occur if a patient has shoulder pain following a fall.
The coder will code according to the guidelines of the specific injury category in case the doctor establishes the injury.
Some injury codes need a seventh character indicating whether it is a first occurrence or healing period.
A key point to consider is that shoulder pain following an accident cannot always be assumed as fracture or sprain. It has to be established by the doctor as an injury before the coder can report on it.
Should Coders Report Shoulder Pain Alongside a Confirmed Diagnosis?
Another common query is whether the coder has to append M25.512 if the physician has determined the root cause of pain in the patient.
This will depend on whether the pain is an integral part of the condition or a separately identifiable condition.
For instance, a patient sees an orthopedic surgeon because he has pains in his shoulder joint. After examining the patient, the surgeon confirms the diagnosis of adhesive capsulitis of the left shoulder joint.
Pain forms part of the condition.
As per the ICD-10-CM coding guidelines, the coder must not code routine symptoms as long as they have not been specified in the instructions given in the codes unless required.
However, there might be times when the coder is supposed to code the other symptom depending on whether there is enough information to do so.
The coder does not have to choose one or the other automatically.
Documentation Requirements for Left Shoulder Pain Coding
Effective documentation is not only important for identifying the affected shoulder. It also relates the patient’s concern to the physician’s assessment and treatment plan.
The below information helps in selecting proper diagnosis codes as well as in supporting the described medical service.
1. Identify the Affected Shoulder
It is vital to indicate which shoulder is affected: right, left, or both.
The physician may state left shoulder pain rather than just shoulder pain if that was the case.
This increases the specificity of the coding and eliminates the necessity of further clarifications.
2. Specify the Onset of the Symptoms and the Medical History
The medical report should indicate when symptoms appeared and what triggered their onset: an accident, physical activity, or some other factor.
Examples of documentation might be:
The patient complains about left shoulder pain for six weeks, with the increasing pain while reaching overhead positions.
3. Include Relevant Examination Findings
Such findings as limited ROM, tenderness, weakness, swelling, or painful movement may be used to validate the findings of the physician.
Such findings should coincide with the physical examination findings conducted by the physician.
The coder must not independently interpret findings obtained from examination to determine a diagnosis that is not documented by the physician.
4. Document the Established Diagnosis
In case there is a cause, this should be indicated in the final assessment.
Let’s assume that there are findings on an MRI report indicating a rotator cuff problem, however, the assessment continues to read shoulder pain.
The coder must be knowledgeable on the documentation guidelines and obtain clarification on the diagnosis.
5. Explain the Plan of Treatment
The treatment decisions made by the clinician such as medication, therapies, diagnostic tests, or referrals should be documented.
Such documentation would help to explain the need for the encounter and the actions taken in the process of treatment of the patient.
Diagnosis codes and treatment plans are two distinct entities in the world of medical billing.
How Shoulder Pain ICD-10 Coding Affects Medical Billing
Shoulder pain diagnoses can justify visits to the doctor’s office, imaging examinations, physical therapy services, and other treatments.
Nevertheless, there is a difference between ICD-10-CM and CPT/HCPCS Level II codes.
ICD-10-CM is used to denote the patient’s disease or reason for care. CPT and HCPCS Level II codes denote services, procedures, and supplies.
It is essential to analyze both parts of the bill.
Office Visits and E/M Coding
Orthopedic specialists and family practitioners regularly evaluate shoulder pain in their patients at the office.
The usual codes for the office/outpatient established patient visit E/M services include 99212 to 99215 based on the type of service and applicable coding guidelines.
M25.512 is not the code that determines the right E/M level to be chosen.
There should be sufficient evidence in favor of applying either medical decision-making or total time criteria for supporting the selected code.
In other words, a person with a simple examination because of slight shoulder pain might need a different level of the E/M service than a person with complicated symptoms.
The same diagnosis code M25.512 is used when there is evidence for left shoulder pain.
Diagnostic Imaging for Shoulder Pain
Physicians sometimes request diagnostic imaging when the clinical findings justify further investigation.
Examples include:
| CPT code | Procedure description |
| 73030 | Shoulder radiologic examination, complete, minimum two views |
| 73221 | MRI of an upper-extremity joint without contrast material |
These codes identify procedures, while M25.512 identifies the patient’s diagnosis or symptom.
A provider should not assume that every patient with shoulder pain requires imaging.
The documentation should explain the clinical indication for the requested study and meet applicable payer requirements.
Physical Therapy and Rehabilitation Services
Physical therapists may treat patients who experience shoulder pain, limited mobility, or functional difficulties.
Common therapy CPT codes include:
| CPT code | Service |
| 97110 | Therapeutic exercises |
| 97112 | Neuromuscular reeducation |
| 97140 | Manual therapy techniques |
| 97530 | Therapeutic activities |
These codes do not automatically become appropriate simply because the patient reports shoulder pain.
The therapist must document the actual intervention, applicable treatment time, patient-specific goals, and relevant functional limitations.
Some payers also apply authorization, plan-of-care, or other therapy requirements.
Medicare therapy claims may require therapy-specific modifiers under the applicable billing rules.
The billing team should verify those requirements rather than adding modifiers routinely to every shoulder-related claim.
Common Left Shoulder Pain Coding Mistakes
Shoulder pain coding errors often begin with incomplete documentation or outdated EHR selections.
| Coding mistake | Potential billing issue | Recommended action |
| Reporting M25.511 for left shoulder symptoms | Incorrect laterality | Match the code to the documented side |
| Selecting M25.519 despite clear documentation of left-sided pain | Unnecessary unspecified coding | Use M25.512 when supported |
| Reporting M25.512 when a confirmed diagnosis better explains the encounter | Incomplete diagnosis representation | Review the final provider assessment |
| Coding a suspected rotator cuff tear as confirmed in an outpatient encounter | Unsupported diagnosis reporting | Follow outpatient uncertain-diagnosis rules |
| Adding pain codes automatically to every established shoulder disorder | Redundant symptom reporting | Review integral-symptom guidance |
| Assuming M25.512 guarantees imaging or therapy coverage | Medical-necessity or coverage questions | Review documentation and payer policy |
A practice may also encounter problems when the diagnosis and treatment records describe different shoulders.
For instance, the assessment may specify left shoulder pain, while an imaging order or therapy note references the right shoulder.
The billing team should investigate the discrepancy rather than silently changing clinical documentation to match the claim.
Practical Shoulder Pain Coding Scenarios
Scenario 1: Left Shoulder Pain Without a Confirmed Cause
A patient visits a primary care physician with left shoulder discomfort after several weeks of strenuous activity.
The clinician examines the joint and recommends conservative management. The assessment identifies left shoulder pain but does not establish a specific disorder.
Diagnosis code: M25.512
This code reflects the documented symptom.
Scenario 2: Bilateral Shoulder Pain
A patient reports discomfort in both shoulders during a follow-up appointment.
The provider evaluates both shoulders and documents bilateral shoulder pain without identifying a definitive cause.
Diagnosis codes: M25.511 and M25.512
The codes identify the right and left shoulders separately.
Scenario 3: Confirmed Left Frozen Shoulder
A physician evaluates shoulder pain and reduced range of motion. The final assessment establishes adhesive capsulitis of the left shoulder.
Diagnosis code: M75.02
The confirmed disorder generally provides a more appropriate diagnosis than an isolated shoulder pain code.
Scenario 4: Suspected Rotator Cuff Tear
A patient reports left shoulder pain after lifting a heavy object.
The provider suspects a rotator cuff tear and requests further evaluation but does not establish the injury during the outpatient visit.
Diagnosis code: M25.512, assuming the record supports left shoulder pain and no other confirmed diagnosis more appropriately represents the encounter.
Coders should not report the suspected tear as a confirmed diagnosis.
Scenario 5: Shoulder Pain With an Established Fracture
A patient falls and develops severe shoulder pain. Imaging confirms a proximal humerus fracture.
The physician documents the fracture and begins treatment.
The coder should select the appropriate fracture code based on the documented location, laterality, fracture characteristics, and encounter requirements.
M25.512 alone would not adequately represent the confirmed injury.
How Medical Practices Can Improve Shoulder Pain Claim Accuracy
A reliable coding workflow should help the billing team identify documentation discrepancies before submitting the claim.
The following steps can improve consistency:
- Confirm laterality. Compare the final assessment with the examination findings and any applicable procedure documentation.
- Identify the most appropriate diagnosis. Determine whether the provider documented only shoulder pain or established a specific underlying condition.
- Review symptom coding. Avoid automatically adding a separate shoulder pain code when an established diagnosis already accounts for the symptom.
- Validate CPT and diagnosis relationships. Confirm that the services reported match the medical record and applicable coding instructions.
- Check payer requirements. Review medical necessity, authorization, therapy documentation, and coverage rules when relevant.
- Track recurring billing issues. Identify repeated errors involving laterality, unsupported diagnoses, and missing documentation.
Practices can also improve their EHR diagnosis favorites by separating right shoulder pain, left shoulder pain, and unspecified shoulder pain into clearly labeled selections.
These small workflow improvements can reduce avoidable corrections and make claim review more consistent.
Conclusion
The correct left shoulder pain ICD 10 code is M25.512 when the provider documents pain in the left shoulder and the clinical record supports symptom-level coding.
M25.511 applies to right shoulder pain, while M25.519 identifies an unspecified shoulder. When a clinician establishes a more specific condition, the billing team should determine whether that diagnosis better represents the encounter.
Accurate shoulder pain coding depends on clear laterality, reliable clinical documentation, appropriate symptom reporting, and proper alignment between diagnosis and procedure codes.
For medical practices, reviewing these details before claim submission helps reduce unnecessary coding corrections and supports a more organized revenue cycle.
Frequently Asked Questions About Shoulder Pain ICD 10
1. What is the ICD 10 code for pain in the left shoulder?
M25.512 is the ICD-10-CM diagnosis code for pain in the left shoulder. It is a valid, billable code for FY 2027 and commonly applies when the provider documents left shoulder pain without establishing a more specific cause.
2. What is the right shoulder pain ICD 10 code?
M25.511 identifies pain in the right shoulder. Coders should use it when the clinical documentation establishes right-sided shoulder pain and symptom coding is appropriate.
3. What code should I use for bilateral shoulder pain?
When the provider documents pain in both shoulders without a more specific diagnosis, coders may assign M25.511 and M25.512. ICD-10-CM does not provide one dedicated bilateral code within this shoulder pain subcategory.
4. Is M25.512 a billable ICD-10-CM code in 2027?
Yes. M25.512 remains billable for FY 2027, covering encounters from October 1, 2026, through September 30, 2027.
5. What is the ICD 10 code for unspecified shoulder pain?
M25.519 identifies pain in an unspecified shoulder. It may apply when the documentation does not identify the affected side and clarification is unavailable.
6. Can shoulder pain and rotator cuff tear appear on the same claim?
They may appear together when documentation and coding guidelines support separate reporting. However, coders should not routinely report pain that forms an integral symptom of a confirmed rotator cuff condition.
7. Can M25.512 support physical therapy billing?
M25.512 may appropriately describe the condition that prompts therapy, but it does not independently establish medical necessity or coverage. The therapist must document the services performed and meet applicable payer requirements.
8. Does chronic left shoulder pain have a different ICD-10 code?
M25.512 identifies left shoulder pain regardless of its duration. Additional pain-related coding may be appropriate in particular circumstances under the ICD-10-CM guidelines for pain coding. Coders should not automatically add a chronic pain code based solely on the symptom’s duration.
