Relapsing polychondritis

This code represents relapsing polychondritis, a rare, chronic, and episodic autoimmune disease characterized by inflammation and destruction of cartilaginous structures throughout the body. It commonly affects the ears, nose, tracheobronchial tree, and joints, but can also involve the eyes, heart, and blood vessels.

Use this code when documentation confirms a diagnosis of relapsing polychondritis, typically based on clinical criteria such as recurrent inflammation of auricular cartilage, nasal cartilage, or laryngotracheal cartilage, along with other systemic manifestations. Supporting documentation should include physician notes detailing the episodic nature of the inflammation and the specific cartilaginous structures involved.

• Ensure the documentation clearly distinguishes relapsing polychondritis from other forms of chondritis or inflammatory arthropathies.
• Code any associated systemic manifestations (e.g., cardiac involvement, ocular inflammation) separately as secondary diagnoses.
• Review the medical record for specific details regarding the affected body sites, as this may influence the specificity of other coded conditions.
