Other specified osteochondropathies, left hand

This code identifies a non-inflammatory disorder affecting the bone and cartilage of the left hand, where the specific type of osteochondropathy is known but does not have a more precise ICD-10-CM code. It encompasses conditions like Kienbock's disease (osteochondrosis of the lunate) or other specified osteochondroses of the carpal bones or metacarpals.

Apply this code when documentation clearly states a diagnosis of an osteochondropathy affecting the left hand, and the specific condition is identified but falls outside of more granular codes. This is appropriate when the physician explicitly diagnoses a "specified" osteochondropathy of the left hand that isn't separately classified.

• Ensure the documentation specifies "left hand" to support laterality.
• Verify that no more specific code exists for the diagnosed osteochondropathy (e.g., Freiberg's disease of the metatarsal would use a foot code).
• Look for terms like "osteochondrosis," "avascular necrosis," or "epiphyseal necrosis" affecting the carpal or metacarpal bones of the left hand.
