Palindromic rheumatism, left ankle and foot

This code signifies a diagnosis of palindromic rheumatism affecting the left ankle and foot. Palindromic rheumatism is a recurrent, self-limiting form of inflammatory arthritis characterized by acute attacks of joint pain and swelling that resolve completely between episodes. It is often considered a precursor to rheumatoid arthritis.

Use this code when documentation clearly indicates a diagnosis of palindromic rheumatism specifically localized to the left ankle and/or foot. This code is appropriate for both initial and subsequent encounters where this condition is being managed. Supporting documentation should include physician notes detailing the episodic nature of the arthritis and its specific anatomical location.

• Ensure documentation specifies "palindromic rheumatism" and not another form of inflammatory arthritis.
• Verify the laterality (left) and specific joint involvement (ankle and foot) are clearly stated.
• Do not confuse with other inflammatory arthropathies like rheumatoid arthritis (M05.-, M06.-) or other specific arthropathies of the ankle and foot (M12.87-).
