Other specified osteochondropathies multiple sites

This code represents a group of rare, non-inflammatory disorders affecting the growth plates or epiphyses of bones, occurring in multiple, unspecified anatomical locations. These conditions involve disturbances in the normal process of endochondral ossification, leading to localized bone necrosis or abnormal bone growth. The specific etiology is often unknown but can include genetic factors, trauma, or vascular compromise.

Use this code when documentation specifies osteochondropathy affecting more than one site, and a more specific code for a named osteochondropathy (e.g., Legg-Calvé-Perthes disease, Osgood-Schlatter disease) or a single, specified site is not applicable. This code is appropriate when the physician's diagnosis explicitly states "other specified osteochondropathies, multiple sites" or provides a description of multiple, non-specific osteochondropathic lesions not classifiable elsewhere.

• Ensure the documentation clearly indicates involvement of multiple sites; if only one site is affected, a more specific code from M93.8- would be appropriate.
• Avoid using this code if a definitive diagnosis for a specific osteochondropathy (e.g., M91.1- for juvenile osteochondrosis of hip and femur) is documented, even if it affects multiple areas.
• Always review the medical record for any further specificity regarding the type or location of the osteochondropathy to determine if a more precise code can be assigned.
