About coding sacroiliac joint chondromalacia
The ICD-10-CM code for sacroiliac joint chondromalacia is M94.259 (Chondromalacia, unspecified hip).
Within M94.25, choose M94.259 (unspecified hip) only when documentation doesn't support a more specific option: right hip (M94.251) and left hip (M94.252).
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.
