Chondrodystrophy

This code represents a group of genetic disorders characterized by abnormal development of cartilage, leading to skeletal deformities. These conditions primarily affect bone growth, resulting in disproportionate short stature and other musculoskeletal abnormalities.

Use this code for diagnoses such as achondroplasia, diastrophic dysplasia, or other specific forms of chondrodystrophy. Documentation should clearly state a diagnosis of chondrodystrophy or a related genetic skeletal dysplasia affecting cartilage formation.

• Do not use for acquired cartilage disorders like osteoarthritis.
• Be specific if a more precise ICD-9-CM code for a particular type of chondrodystrophy is available (e.g., 756.5 for achondroplasia).
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, especially for genetic counseling or management of the condition.
