Left Shoulder Pain ICD 10: Coding and Billing Guide

Accurate diagnosis coding is important for physical therapy practices handling patients with shoulder pain. Using the correct Left Shoulder Pain ICD 10 code helps providers document the patient’s condition, support medical necessity, and submit cleaner insurance claims. For cases involving pain specifically in the left shoulder, M25.512 is the commonly used ICD-10-CM code.

What Is the Left Shoulder Pain ICD 10 Code?

The Left Shoulder Pain ICD 10 code is M25.512, which represents pain in the left shoulder. It may be used when the patient has documented shoulder pain but a more specific underlying diagnosis has not been established.

However, providers should always code to the highest level of specificity supported by the medical record. If documentation identifies a specific condition causing the pain, the appropriate diagnosis code for that condition may be more suitable.

Common Conditions Related to Left Shoulder Pain

Left shoulder pain may result from several conditions, including:

• Rotator cuff injuries

• Shoulder impingement

• Adhesive capsulitis or frozen shoulder

• Osteoarthritis

• Bursitis

• Sprains and strains

• Post-surgical shoulder problems

For example, M75.42 may be used for impingement syndrome of the left shoulder, while M75.02 represents adhesive capsulitis of the left shoulder. The diagnosis selected should match the provider’s documented findings.

Documentation Tips for Accurate Coding

Complete documentation can help support the selected ICD-10 code and reduce billing issues. Physical therapy records should clearly describe the patient's symptoms, affected side, pain location, range of motion, strength, functional limitations, relevant medical history, and examination findings.

If imaging or other diagnostic testing is available, relevant results should also be included in the medical record. Clear documentation helps connect the diagnosis with the treatment plan and demonstrates medical necessity.

How Accurate Coding Supports Reimbursement

Incorrect or incomplete coding can contribute to claim delays, denials, and payment problems. Using M25.512 when supported by the documentation helps create consistency between the patient's diagnosis, therapy services, and insurance claim.

Final Thoughts

Understanding the Left Shoulder Pain ICD 10 code M25.512 is important for accurate documentation and billing. Providers should review the clinical documentation carefully and use a more specific diagnosis code whenever the underlying condition is clearly established. Accurate coding, complete documentation, and proper claim submission can help reduce billing issues and support compliant reimbursement.
