Left Shoulder Pain ICD-10: M25.512 Code, Guide for Providers

The correct Left Shoulder Pain ICD-10 code is M25.512, which identifies pain in the left shoulder when a provider’s assessment supports symptom-level reporting. However, physicians must determine whether the complaint represents an unexplained symptom or a confirmed shoulder condition before selecting the final diagnosis code.

Incomplete documentation, incorrect laterality, and unsupported diagnoses can create avoidable coding discrepancies. This guide explains when to report M25.512, how to document left shoulder pain, and how accurate diagnosis selection supports the medical billing process.

What Is the ICD-10 Code for Left Shoulder Pain in 2027?

ICD 10 Code for Left Shoulder Pain: M25.512 Pain in left shoulder

This code belongs to Chapter 13 of ICD-10-CM codes that relate to diseases of the musculoskeletal system and connective tissue.

Whereas M25.512 provides information about the exact anatomical position and laterality of the pain suffered by the patient, there is no information regarding the cause of the pain and whether the patient suffers from any arthritic, bursitis, rotator cuff tear, or other musculoskeletal conditions.

This code is still valid and eligible for billing purposes until FY 2027, during which dates of service are from October 1, 2026, to September 30, 2027. Physicians may refer to the CMS ICD-10-CM code files to know the appropriate classification.

What Does M25.512 Actually Represent?

M25.512 is a symptom code that is not actually an orthopedic musculoskeletal disorder diagnosis.

This code may be applied by a physician to describe symptoms of left shoulder pain where no condition can be diagnosed by the doctor during a consultation with the patient.

A patient may complain about pain when lifting his left arm up. There is some pain and tenderness felt by the doctor, but there is no diagnosis of the condition.

In this case, M25.512 can be considered correct for the recorded assessment, but the physician shouldn’t diagnose a rotator cuff tear or other structural condition without a proper diagnosis.

When Should Healthcare Providers Use ICD-10 M25.512?

Providers should consider M25.512 when the clinical assessment identifies left shoulder pain without confirming a specific condition responsible for the complaint.

Use of this code may be appropriate during visits to primary care physicians, orthopedic specialists, sports medicine doctors, and others when assessing this symptom.

Left Shoulder Pain Without a Confirmed Diagnosis

A patient consults a primary care physician for left shoulder pain that occurred some days ago. Physical examination is done on the shoulder, and the patient is found to be tender, but no musculoskeletal condition is identified.

Where the evaluation determines the patient has left shoulder pain, code M25.512 can be used for the condition being assessed in the visit.

It is important that the physician does not diagnose what the physical findings do not suggest..

Left Shoulder Pain After Physical Activity

The patient complains of pain experienced after weight training or repeating overhead activities. The physician checks the shoulder but cannot find any injuries.

Even though physical exercise is vital in this situation for making the diagnosis, this doesn’t necessarily mean that there are any injuries in the shoulder joint, like shoulder strain or rotator cuff injury.

Hence, symptoms-based coding may be appropriate where the provider’s diagnosis confirms left shoulder pain only.

Left Shoulder Pain With Limited Range of Motion

Disruption of movement is usually associated with shoulder disorders, but restricted movement does not indicate any particular musculoskeletal disease.

For example, it may be documented that the patient has painful movements in the left shoulder, but not necessarily adhesive capsulitis or some other musculoskeletal disorder.

In such a situation, the use of M25.512 is justified in case the diagnostic procedures have established left shoulder pain without the specific diagnosis.

Left Shoulder Pain Requiring Further Evaluation

In certain cases, a provider might order imaging studies, consultations with specialists, and/or other tests to help identify the cause of shoulder pain.

ICD-10-CM Official Guidelines for Coding and Reporting for Outpatient Encounters in FY2027 state that healthcare providers must not report uncertain diagnosis as definite conditions.

Instead, they should only make note of the conditions or symptoms that are supported by the encounter. Thus, M25.512 is still appropriate if a definite diagnosis is not made during the course of the encounter.

What Documentation Supports the Left Shoulder Pain ICD-10 Code?

Proper coding for ICD 10 left shoulder pain relies on the doctor’s records. “Shoulder pain” noted in the doctor’s note may be insufficient details to assign a left-sided diagnosis code.

Although M25.512 identifies a symptom, the medical record should still explain what the provider evaluated and why the diagnosis represents the encounter.

Identify the Correct Shoulder and Anatomical Location

The physician must note the presence of the left shoulder in cases where the history and physical examination findings point to this area.

It is important to do this since any pain near the shoulder will include other anatomic areas. The pain could be reported by the patient to occur in the neck region, the upper arm, or in the shoulder joint region.

The physician needs to specify the correct anatomic area instead of including any pain in the shoulder under M25.512.

Describe the Patient’s Symptoms and History

The significant aspects related to the patient’s symptoms must be put down in the medical history of the patient, including pain onset, pain cause, movement pain, and loss of function.

For instance, the patient might be suffering from pain in his left shoulder when he extends his arm.

Nevertheless, use of the descriptive terms chronic, stabbing, episodic, and activity-related to describe the pain alone cannot provide a diagnosis for the musculoskeletal problem.

Record Relevant Physical Examination Findings

A physician should document findings that back up his diagnosis. Findings may include localized tenderness, limited range of motion, and many others.

These results can be used to validate the history, but will not be useful in identifying the reason for the problem.

For example, shoulder movement causing pain does not indicate the presence of rotator cuff tear.

Clearly State the Clinical Assessment

The assessment needs to differentiate between a documented symptom and an actual musculoskeletal condition.

Example of appropriate documentation:

The above document shows the affected side, examination results, and assessment of the patient.

However, the statement “pain in shoulder, may be tear” is not clear concerning the side and established diagnosis.

By comparison, a note stating only “shoulder discomfort, possible tear” creates uncertainty about laterality and the established diagnosis.

Document the Clinical Plan When Relevant

Physicians should indicate the evaluation, therapy, test, referral, or follow-up which is considered medically necessary for the patient.

But they should focus on documenting what has been done and not add extra information just for the sake of coding diagnosis.

Also, documentation of good assessment and therapy helps medical coders in deciding if the coded diagnosis matches with the service provided

Left Shoulder Pain vs. Right Shoulder Pain ICD-10: Why Laterality Matters

ICD-10-CM provides separate diagnosis codes for left, right, and unspecified shoulder pain. Therefore, providers must select the code that matches the documented anatomical side.

M25.512 vs. M25.511

The primary difference between left shoulder pain coding and right shoulder pain ICD 10 reporting is laterality.

M25.512 refers to pain in the left shoulder, while M25.511 refers to pain in the right shoulder. These codes pertain to the symptom and not the cause of the pain.

Coding with M25.511 will contradict the physician’s documentation if there is pain in the left shoulder. If the documentation does not indicate which side of the shoulder is in pain, the coder should not make any assumptions from previous records.

When Should Providers Use M25.519?

The medical code M25.519 pertains to the pain in the shoulder but does not state on which side this pain occurs.

Nevertheless, when it is possible to determine on which side the pain occurs, it needs to be stated in order to make a particular coding.

Should Providers Report M25.512 When a Shoulder Disorder Is Diagnosed?

A confirmed shoulder diagnosis can change how healthcare providers report pain during an encounter.

For instance, the patient may first see the practitioner for unexplained left shoulder pain. For this particular consultation, the physician will be coding for the symptoms alone; therefore, the appropriate code is M25.512.

Nevertheless, after another follow-up consultation, there can be evidence of a specific musculoskeletal problem. This will necessitate an update of the coding process as well.

When Does a Confirmed Diagnosis Take Priority?

According to the ICD-10-CM Official Coding Guidelines, signs and symptoms usually related to a definite disease should not be coded separately unless otherwise instructed by the classification.

In such cases, with evidence of a definite shoulder disorder with the pain being a definite sign of the illness, there is need for the diagnosis to be coded separately without the need for code M25.512.

The final decision depends on the documented circumstances and applicable coding instructions.

Can Providers Report Both Shoulder Pain and an Underlying Diagnosis?

In certain cases, additional symptom coding is necessary if there is documentation of an independently reportable condition, and if the classification instructions allow for it.

Nonetheless, it cannot be assumed that any shoulder condition confirmed by the physician needs an additional pain code.

This is because an analysis of the connection between the symptom and the confirmed condition should be made.

How to Distinguish Left Shoulder Pain From Other Anatomical Complaints

One of the most important shoulder pain ICD 10 decisions involves identifying the actual anatomical location of the patient’s discomfort.

Sometimes patients feel pain around their shoulder area, but the problem does not necessarily affect the shoulder itself. Therefore, diagnosis should be based on the physician’s diagnosis rather than on the general patient description.

Left Shoulder Pain vs. Left Upper-Arm Pain

The individual might complain of pain in the upper arm, which he refers to as shoulder pain. Nevertheless, such sites cannot be used interchangeably when coding according to ICD-10-CM criteria.

Physicians should clarify whether the assessment identifies pain in the shoulder, upper arm, or another structure.

Selecting M25.512 solely because the complaint occurs near the shoulder may misrepresent the documented anatomical site.

Neck Pain Radiating Toward the Left Shoulder

Some patients experience discomfort that extends from the cervical region toward the shoulder.

When evaluating these complaints, clinicians should document the relevant anatomical findings and established assessment.

Coders should not automatically assign a shoulder pain diagnosis simply because discomfort extends into the shoulder region.

Pain Near the Shoulder Without an Established Cause

The search phrase icd shoulder pain may help providers locate coding resources, but clinical documentation must establish the anatomical location.

When the assessment identifies left shoulder pain without a definitive underlying diagnosis, M25.512 may be appropriate.

If the physician identifies another anatomical site or establishes a specific condition explaining the symptoms, diagnosis selection should reflect that assessment.

Common Left Shoulder Pain ICD-10 Coding Mistakes

Even when healthcare providers recognize the correct diagnosis code, documentation inconsistencies can complicate claim preparation.

Most errors involve unclear laterality, unsupported diagnoses, or failure to review updated clinical information.

Common Coding Mistake	Potential Problem	Recommended Approach
Documenting only shoulder pain	Laterality remains unclear	Specify the left shoulder when supported
Selecting M25.511	Code conflicts with documented left-sided pain	Confirm the affected side
Assuming a rotator cuff tear	Pain alone does not establish a tear	Follow the confirmed assessment
Confusing upper-arm and shoulder pain	Anatomical location may be incorrect	Clarify the site of pain
Reporting suspected diagnoses as confirmed	May conflict with outpatient coding guidelines	Report the established condition or symptom
Reusing M25.512 without reviewing the note	The diagnosis may have changed	Review the current encounter

Avoid Reusing Outdated Diagnosis Codes

The patient might be treated for the same shoulder complaint during several visits. Nevertheless, the assessment by the provider may vary depending on new information obtained during examination.

For example, the use of the code M25.512 can be appropriate during the process of the first evaluation. In case this shoulder-specific disease was detected during a second visit, the coder should reassess the chosen diagnostic.

The reuse of the previous symptom code may lead to a mismatch between the current evaluation and diagnosis.

Do Not Assume a Billable Code Guarantees Payment

M25.512 is a legitimate and billable ICD-10-CM code; yet, legitimacy does not equate to demonstrating coverage and necessity of treatment. The insurance company can evaluate the correlation between the stated diagnosis and performed service, as well as the conditions required for coverage.

In this respect, the provider must assess the legitimacy of the given diagnosis instead of taking into account one particular symptom code.

How Accurate ICD-10 Coding Supports Left Shoulder Pain Claims

Diagnosis coding represents one part of the medical billing workflow. The physician documents the encounter, the coding team identifies reportable diagnoses, and the billing team prepares the claim using the relevant information.

When these steps lack consistency, practices may need additional documentation reviews, claim corrections, or clarification before submission.

Match the Diagnosis With the Documented Encounter

Consider a physician who evaluates unexplained left shoulder pain and records the symptom as the final assessment.

If the billing team selects M25.512, that code should accurately correspond to the documentation.

However, the team must still consider relevant claim requirements rather than treating diagnosis selection as the only condition for appropriate billing.

Resolve Documentation Questions Before Submission

When the assessment and selected diagnosis conflict, medical coding professionals should review the complete record and follow established clarification procedures.

For instance, a clinical note may identify left shoulder pain in the history but refer to the right shoulder in the assessment.

Rather than selecting a side arbitrarily, the coding team should resolve the inconsistency through the organization’s documentation process.

Review FY2027 Coding Requirements

Healthcare organizations should apply the ICD-10-CM classification relevant to the patient’s date of service.

The Centers for Medicare & Medicaid Services ICD-10 resources provide official code files and implementation information.

The FY2027 ICD-10-CM code set applies to encounters from October 1, 2026, through September 30, 2027.

Frequently Asked Questions

What Is the ICD-10 Code for Pain in the Left Shoulder?

M25.512 is the ICD-10-CM code for pain in the left shoulder. Providers may use it when their assessment supports reporting the symptom without a more definitive diagnosis changing the code selection. The code identifies the affected anatomical site and laterality.

Is M25.512 a Billable ICD-10 Code for 2027?

Yes. M25.512 remains a valid and billable ICD-10-CM code for FY2027. It identifies pain in the left shoulder and does not require an additional character to complete the diagnosis code.

What Is the Difference Between M25.511 and M25.512?

M25.511 represents pain in the right shoulder, while M25.512 identifies pain in the left shoulder. The distinction depends on laterality, so physicians should clearly document the affected side during the encounter.

Can Physicians Use M25.512 When the Cause of Shoulder Pain Is Unknown?

Yes. When a physician evaluates left shoulder pain without establishing a definitive underlying cause, M25.512 may appropriately represent the documented symptom. However, the final selection must reflect the clinical assessment and applicable coding rules.

Can Providers Report Left Shoulder Pain and a Confirmed Shoulder Condition Together?

Not automatically. Pain routinely associated with a confirmed shoulder disorder generally does not require separate reporting unless classification instructions or the documented circumstances support an additional symptom code. Providers and coders should review the relationship between the symptom and the established diagnosis.
