Unspecified juvenile osteochondrosis, unspecified leg

This code signifies an uncharacterized developmental disorder affecting bone and cartilage in an immature individual, specifically within an unspecified lower limb. It indicates a condition where the precise type of juvenile osteochondrosis has not been determined or documented.

Apply this code when documentation confirms a diagnosis of juvenile osteochondrosis affecting a leg, but lacks specificity regarding the exact type (e.g., Legg-Calvé-Perthes disease, Osgood-Schlatter disease) or the specific bone involved. This code is appropriate when the physician's notes simply state "juvenile osteochondrosis of the leg" without further detail.

• Avoid using this code if the specific type of juvenile osteochondrosis is known and documented (e.g., M91.1- for Legg-Calvé-Perthes).
• Always seek clarification from the provider if the documentation is vague, to allow for more specific coding.
• This code should be used as a last resort when no further specificity can be obtained regarding the type or location within the leg.
