About M96.A2

M96.A2 is the ICD-10-CM diagnosis code for fracture of one rib associated with chest compression and cardiopulmonary resuscitation. It belongs to category M96 (intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified), block M96 (intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M96.A (fracture of ribs, sternum and thorax associated with compression of the chest and cardiopulmonary resuscitation), M96.A2 is specifically for fracture of one rib associated with chest compression and cardiopulmonary resuscitation. Related codes cover fracture of sternum associated with chest compression and cardiopulmonary resuscitation (M96.A1), multiple fractures of ribs associated with chest compression and cardiopulmonary resuscitation (M96.A3), Flail chest associated with chest compression and cardiopulmonary resuscitation (M96.A4) and other fracture associated with chest compression and cardiopulmonary resuscitation (M96.A9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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), DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363), DRG 964 (Other Multiple Significant Trauma with CC, relative weight 1.4972) and DRG 965 (Other Multiple Significant Trauma without CC/MCC, relative weight 1.0059), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue) and MDC 24 (Multiple Significant Trauma), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2023, effective October 1, 2022.
