About coding rib slipped
The ICD-10-CM code for rib slipped is M89.8X8 (Other specified disorders of bone, other site).
Within M89.8X, choose M89.8X8 (other site) only when documentation doesn't support a more specific option: multiple sites (M89.8X0), shoulder (M89.8X1), upper arm (M89.8X2), forearm (M89.8X3), hand (M89.8X4), thigh (M89.8X5), lower leg (M89.8X6), ankle and foot (M89.8X7) 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.
