ICD-10 Code M02.812 – Other reactive arthropathies, left shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.812 – Other reactive arthropathies, left shoulder
What it is
This code identifies a reactive arthropathy affecting the left shoulder. Use it when documentation specifies an inflammatory joint condition linked to a prior infection or reactive process in that shoulder.
Clinical signs
Clinical features vary; refer to documentation. You may see shoulder pain, stiffness, swelling, and reduced range of motion, with findings consistent with inflammatory arthritis rather than trauma alone.
When to use this code
Use this code when the provider documents other reactive arthropathy in the left shoulder and laterality is clear. It is appropriate when the record links the condition to a reactive arthritic process, not a nonspecific shoulder pain diagnosis.
Do not use for
Do not use this code for unspecified shoulder pain, degenerative joint disease, or traumatic shoulder injury. Check documentation if the reactive cause, joint site, or laterality is not stated.
Coding tip
Confirm both the reactive arthropathy diagnosis and left shoulder laterality in the note before assigning M02.812.
