About coding multiple joints osteochondropathy
The ICD-10-CM code for multiple joints osteochondropathy is M93.99 (Osteochondropathy, unspecified multiple sites).
Within M93.9 (osteochondropathy, unspecified), M93.99 is specifically for osteochondropathy, unspecified multiple sites. Related codes cover of unspecified site (M93.90), 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) 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.
