About coding Arthrokatadysis
The ICD-10-CM code for Arthrokatadysis is M24.7 (Protrusio acetabuli).
Within M24 (other specific joint derangements), M24.7 is specifically for Protrusio acetabuli. Related codes cover Loose body in joint (M24.0), other articular cartilage disorders (M24.1), disorder of ligament (M24.2), pathological dislocation of joint, not elsewhere classified (M24.3), recurrent dislocation of joint (M24.4), contracture of joint (M24.5), ankylosis of joint (M24.6), not elsewhere classified (M24.8) 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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), 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.
