About Z97.12
Z97.12 is the ICD-10-CM diagnosis code for presence of artificial left arm (complete) (partial). It belongs to category Z97 (presence of other devices), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) 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 Z97.1 (presence of artificial limb (complete) (partial)), Z97.12 is specifically for presence of artificial left arm (complete) (partial). Related codes cover unspecified (Z97.10), right arm (complete) (partial) (Z97.11), right leg (complete) (partial) (Z97.13), left leg (complete) (partial) (Z97.14), arms, bilateral (complete) (partial) (Z97.15) and legs, bilateral (complete) (partial) (Z97.16).
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.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
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 V43.7 (limb replaced by other means).
