Arthropathies in oth diseases classd elswhr, left shoulder

This code signifies an inflammatory or degenerative joint condition affecting the left shoulder, arising as a manifestation of another underlying systemic disease. This is not a primary shoulder disorder but rather a secondary complication of a separate, specified medical condition.

Apply this code when documentation clearly links left shoulder arthropathy to an underlying systemic disease, such as psoriatic arthritis, inflammatory bowel disease, or sarcoidosis, and the specific underlying disease has its own ICD-10-CM code. Ensure the medical record specifies "left shoulder" and identifies the primary condition.

• Always sequence the underlying systemic disease code first, followed by this code.
• Do not use this code for primary osteoarthritis or rheumatoid arthritis of the shoulder; those have specific codes.
• Verify the documentation explicitly states "left shoulder" and not just "shoulder" or "bilateral."
