Juvenile osteochondrosis of metatarsus, left foot

This code represents a developmental disorder affecting the growth plates (epiphyses) of the metatarsal bones in the left foot of a juvenile patient. It involves aseptic necrosis and subsequent reossification of the metatarsal heads, often leading to pain and deformity. This condition is commonly known as Freiberg's disease when affecting the metatarsal heads.

Use this code for a confirmed diagnosis of osteochondrosis specifically impacting the metatarsal bones of the left foot in a pediatric or adolescent patient. Documentation should clearly indicate the affected foot (left) and the specific bones involved (metatarsals), often supported by imaging findings such as X-rays or MRI.

• Ensure the documentation specifies "left foot" and "metatarsus" to avoid laterality and anatomical site errors.
• Differentiate from other osteochondroses affecting different foot bones (e.g., tarsals, calcaneus) or other anatomical sites.
• Consider sequencing with codes for associated symptoms like pain (e.g., M79.672) or gait abnormalities (e.g., R26.9) if documented.
