ICD10 code of Chondrodysplasia Punctata and ICD9 code

Chondrodysplasia Punctata is primarily classified under the ICD-10 code Q77.3 (Chondrodysplasia punctata), while the historical ICD-9 code for this condition is 756.51. These diagnostic codes are essential for medical billing and clinical tracking, though they encompass a broad spectrum of underlying genetic disorders.

What is the clinical significance of Chondrodysplasia Punctata?

Chondrodysplasia Punctata refers to a heterogeneous group of skeletal disorders characterized by stippled epiphyses (calcium deposits in the cartilage) visible on X-rays during infancy. Because Chondrodysplasia Punctata can be caused by various genetic mutations—including X-linked dominant, X-linked recessive, and autosomal recessive patterns—the clinical presentation varies significantly from mild skeletal changes to severe developmental delays and dermatological involvement.

How is Chondrodysplasia Punctata diagnosed?

Diagnosis of Chondrodysplasia Punctata often begins with identifying characteristic calcifications on radiographic imaging. Given the complexity of the condition, clinicians utilize a multidisciplinary approach to confirm the diagnosis, which typically includes the following steps:

• Review of family history to determine the inheritance pattern.


• Clinical examination for associated features like cataracts, skin lesions (ichthyosis), and hearing loss.


• Biochemical testing to measure very-long-chain fatty acids or cholesterol precursors.


• Molecular genetic testing to identify specific mutations (e.g., EBP, ARSE, or PEX genes).

Is Chondrodysplasia Punctata hereditary?

Yes, Chondrodysplasia Punctata is a genetic condition. Depending on the specific subtype, the inheritance can be X-linked or autosomal. Because Chondrodysplasia Punctata is rare, families are encouraged to seek genetic counseling to understand the recurrence risk for future pregnancies and the specific implications for family members.
