Other osteochondropathies (M93) ICD-10-CM
The M93 code range covers other osteochondropathies with 139 ICD-10-CM diagnosis codes. 105 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M93 range.
Cartilage
A non-vascular form of connective tissue composed of CHONDROCYTES embedded in a matrix that includes CHONDROITIN SULFATE and various types of FIBRILLAR COLLAGEN. There are three major types: HYALINE CARTILAGE; FIBROCARTILAGE; and ELASTIC CARTILAGE.
Femur Head Necrosis
Aseptic or avascular necrosis of the femoral head. The major types are idiopathic (primary), as a complication of fractures or dislocations, and LEGG-CALVE-PERTHES DISEASE.
Legg-Calve-Perthes Disease
A particular type of FEMUR HEAD NECROSIS occurring in children, mainly male, with a course of four years or so.
Osteochondritis
Inflammation of a bone and its overlaying CARTILAGE.
Osteochondritis Dissecans
A type of osteochondritis in which articular cartilage and associated bone becomes partially or totally detached to form joint loose bodies. Affects mainly the knee, ankle, and elbow joints.
About the M93 Code Range
The ICD-10 codes grouped under M93 pertain to "Other osteochondropathies," a category covering various bone and cartilage disorders, such as slipped upper femoral epiphysis and osteochondritis dissecans. These codes specify the condition's location, stability, and laterality, aiding precise classification for diagnosis and treatment.
This section includes codes for slipped upper femoral epiphysis (nontraumatic), with subcodes distinguishing acute, chronic, or unstable cases, and specifying involvement of the right, left, bilateral, or unspecified hip. For example, terms like "slipped right upper capital femoral epiphysis" correspond to M93.001. Additionally, osteochondritis dissecans, a condition where bone and cartilage fragments can separate, is categorized here with detailed codes according to affected joints such as the shoulder, elbow, wrist, hip, or knee. Synonyms like "familial osteochondritis dissecans" and "osteonecrosis of head of femur" help clarify the matching ICD-10 codes. Other subcategories cover specified or unspecified osteochondropathies at various sites (e.g., shoulder, upper arm, hand), including apophysitis and traction apophysitis ("M93.80"). Using these precise codes improves clarity in medical records relating to bone/cartilage disorders and assists healthcare providers and coders in identifying the exact condition and anatomical site involved.
