ICD10 code of Achondrogenesis and ICD9 code

Achondrogenesis is classified under ICD-10 code Q77.0 (Achondrogenesis) and ICD-9 code 756.4 (Chondrodystrophy). These codes are essential for medical documentation, insurance billing, and tracking the clinical management of infants affected by this severe skeletal dysplasia.

What is the clinical classification of Achondrogenesis?

Achondrogenesis represents a group of rare, lethal skeletal dysplasias characterized by severe shortening of the limbs and a small trunk. Because Achondrogenesis significantly impacts bone development in utero, it is categorized by the World Health Organization under congenital malformations of the musculoskeletal system. Accurate coding helps clinicians and researchers distinguish Achondrogenesis from other forms of dwarfism, ensuring that the specific needs of families are addressed by appropriate specialists.

How is Achondrogenesis diagnosed?

The diagnosis of Achondrogenesis is typically established through prenatal ultrasound or postnatal radiographic examination. Key diagnostic features often include:

• Severe micromelia (shortening of limbs)


• Lack of ossification in the vertebral bodies, sacrum, and pubic bones


• A disproportionately large cranium relative to the trunk


• Narrow chest cavity leading to pulmonary hypoplasia

Is Achondrogenesis hereditary?

Achondrogenesis is primarily inherited in an autosomal recessive pattern, meaning both parents typically carry one copy of a mutated gene, such as COL2A1 or SLC35D1. Genetic counseling is vital for families affected by Achondrogenesis to understand the 25% recurrence risk in future pregnancies. Our community at DiseaseMaps.org currently includes 27 individuals and families who have navigated the complexities of this diagnosis and are available to share their lived experiences.

Next steps

• Consult with a clinical geneticist to discuss recurrence risks and molecular testing.


• Connect with the 27 members of the DiseaseMaps.org Achondrogenesis community for peer support.


• Request a referral to a perinatologist or a specialized pediatric skeletal dysplasia center for comprehensive care planning.
