Other specified rheumatoid arthritis, left shoulder

This code signifies a form of rheumatoid arthritis that doesn't fit into more specific categories, specifically affecting the left shoulder joint. It indicates an inflammatory autoimmune condition causing pain, swelling, and potential joint damage in that particular anatomical site.

This code is appropriate when documentation clearly states a diagnosis of "other specified rheumatoid arthritis" impacting the left shoulder. It should be used when the physician has ruled out or not specified other common types of rheumatoid arthritis (e.g., seropositive, seronegative) but has definitively identified the left shoulder as the affected joint.

• Ensure the documentation explicitly identifies the left shoulder as the affected joint; laterality is crucial for this code.
• Verify that the diagnosis is "other specified" rheumatoid arthritis, not an unspecified or another specific type.
• Consider sequencing this code with a code for any associated systemic manifestations or complications of rheumatoid arthritis.
