About Z44.112
Z44.112 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of complete left artificial leg. It belongs to category Z44 (encounter for fitting and adjustment of external prosthetic device), block Z40-Z53 (Encounters for other specific health care) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z44.11 (encounter for fitting and adjustment of complete artificial leg), Z44.112 is specifically for encounter for fitting and adjustment of complete left artificial leg. Related codes cover right artificial leg (Z44.111) and unspecified leg (Z44.119).
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 559 (Aftercare, Musculoskeletal System and Connective Tissue with MCC, relative weight 1.8088), DRG 560 (Aftercare, Musculoskeletal System and Connective Tissue with CC, relative weight 1.1238) and DRG 561 (Aftercare, Musculoskeletal System and Connective Tissue without CC/MCC, relative weight 0.8258), 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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V52.1 (fitting and adjustment of artificial leg (complete) (partial)).
