Left shoulder pain is a common complaint in healthcare, but it is not a diagnosis on its own. For providers, assigning the correct ICD-10-CM code is essential to ensure accurate billing, compliance, and proper documentation. The ICD-10-CM code for left shoulder pain is M25.512.
This article explores the details of ICD-10 codes for left shoulder pain, why accurate coding is vital for revenue cycle success, and how partnering with experts like Allzone through ICD coding services and ICD coding outsourcing can streamline operations and reduce claim denials.
Breaking Down the ICD-10 Code M25.512
The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) is the official U.S. system for coding diagnoses, symptoms, and medical procedures. These codes ensure consistency in patient records, insurance claims, and healthcare data tracking.
M25 – Other joint disorders, not elsewhere classified

.51 – Shoulder region

2 – Left side

This code is classified as a symptom code, meaning it identifies the patient’s complaint (pain) rather ...
... than a confirmed diagnosis. Providers typically use it for initial visits before further diagnostic tests, such as MRI or ultrasound, identify the underlying cause (e.g., rotator cuff tear).

Why Accurate Medical Coding Matters
Accurate ICD-10 coding is the foundation of a healthy revenue cycle. Errors in coding can lead to:
Claim denials – Incorrect codes may fail to prove medical necessity.

Payment delays – Even minor coding errors can slow reimbursements.

Compliance risks – Regulatory bodies like CMS enforce strict coding standards.

Incomplete patient records – Correct codes ensure continuity of care.

While M25.512 is useful for initial visits, providers should update it with a more specific diagnosis code once identified. For example:
S46.012A – Strain of rotator cuff muscle of the left shoulder, initial encounter.

Common Causes of Left Shoulder Pain and ICD-10 Codes
Left shoulder pain can result from multiple conditions, each with its own ICD-10-CM code:
Rotator cuff tear (left) – M75.122

Adhesive capsulitis (frozen shoulder) – M75.02

Bursitis (left shoulder) – M75.52

Osteoarthritis (left shoulder) – M19.012

Shoulder impingement syndrome – M75.42

Dislocation (left shoulder, initial encounter) – S43.002A

By selecting the most precise code, providers strengthen documentation, ensure compliance, and support smooth claim approvals.
