Palindromic rheumatism, right shoulder

This code signifies a recurrent, self-limiting inflammatory arthritis affecting the right shoulder joint. Episodes are characterized by acute onset of pain, swelling, and stiffness, which resolve completely within hours to days, often without residual joint damage.

Apply this code when documentation clearly indicates a diagnosis of palindromic rheumatism specifically affecting the right shoulder. This diagnosis is typically made based on the characteristic migratory and episodic nature of the arthritis, often with negative serological markers for other inflammatory arthropathies.

• Ensure the documentation specifies "palindromic rheumatism" and not another form of inflammatory arthritis.
• Verify the laterality is explicitly stated as "right shoulder" to avoid incorrect assignment.
• Consider co-reporting codes for any associated systemic conditions or complications, if documented.
