About coding osteochondropathy
The ICD-10-CM code for osteochondropathy is M93.90 (Osteochondropathy, unspecified of unspecified site). The official index lists 24 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M93.90.
Within M93.9, choose M93.90 (of unspecified site) only when documentation doesn't support a more specific option: of shoulder (M93.91), of upper arm (M93.92), of forearm (M93.93), of hand (M93.94), of thigh (M93.95), lower leg (M93.96), of ankle and foot (M93.97), other (M93.98) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
