Palindromic rheumatism, right knee

This code signifies a diagnosis of palindromic rheumatism affecting the right knee. Palindromic rheumatism is a recurrent, self-limiting inflammatory arthritis characterized by acute, episodic attacks of joint pain and swelling that resolve completely between episodes.

Use this code when documentation specifies a diagnosis of palindromic rheumatism localized to the patient's right knee. This diagnosis is typically supported by a physician's assessment, patient history of recurrent, transient arthritis, and exclusion of other inflammatory arthropathies.

• Ensure the documentation explicitly states "right knee" for laterality.
• Do not confuse with chronic inflammatory arthropathies like rheumatoid arthritis, as palindromic rheumatism is episodic and resolves completely.
• Consider additional codes for any associated systemic manifestations or complications, if documented.
