ICD-10 code for left total hip replacement

The ICD-10-CM code for left total hip replacement is Z96.642 (Presence of left artificial hip joint). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z96.642.

It is also searched as status post left hip replacement.

Within Z96.64 (presence of artificial hip joint), Z96.642 is specifically for presence of left artificial hip joint. Related codes cover right artificial hip joint (Z96.641), bilateral (Z96.643) and unspecified artificial hip joint (Z96.649).

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.
