Diastrophic dysplasia

This code identifies a rare, inherited skeletal dysplasia characterized by short stature, short limbs, and distinctive joint and bone abnormalities. It results from a genetic mutation affecting cartilage development, leading to progressive deformities. Patients typically present with clubfoot, hitchhiker's thumb, cleft palate, and spinal curvature.

Assign this code for patients diagnosed with diastrophic dysplasia, a specific form of osteochondrodysplasia. Documentation should clearly state the diagnosis of diastrophic dysplasia, often supported by genetic testing results, radiographic findings, and clinical presentation. This code is appropriate for both initial diagnosis and ongoing management of the condition.

• Ensure documentation specifies "diastrophic dysplasia" to differentiate from other skeletal dysplasias.
• Code all associated musculoskeletal manifestations, such as clubfoot (Q66.0-Q66.9), scoliosis (M41.-), or cleft palate (Q35.1-Q37.9), as secondary diagnoses.
• Do not confuse with other forms of short-limbed dwarfism without the specific diagnostic criteria for diastrophic dysplasia.
