About M96.84

M96.84 is the ICD-10-CM diagnosis code for postprocedural hematoma and seroma of a musculoskeletal structure following a procedure. 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 a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within M96.8 (other intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified), M96.84 is specifically for postprocedural hematoma and seroma of a musculoskeletal structure following a procedure. Related codes cover intraoperative hemorrhage and hematoma of a musculoskeletal structure complicating a procedure (M96.81), accidental puncture and laceration of a musculoskeletal structure during a procedure (M96.82), postprocedural hemorrhage of a musculoskeletal structure following a procedure (M96.83) and other intraoperative and postprocedural complications and disorders of the musculoskeletal system (M96.89).

To report this condition, pick the subcode that matches the documentation: M96.840 (procedure), M96.841 (procedure), M96.842 (procedure) and M96.843 (procedure).

It was added in FY2017, effective October 1, 2016.
