About Z44.32
Z44.32 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of external left breast prosthesis. 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 Z44.3 (encounter for fitting and adjustment of external breast prosthesis), Z44.32 is specifically for encounter for fitting and adjustment of external left breast prosthesis. Related codes cover unspecified breast (Z44.30) and right breast prosthesis (Z44.31).
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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 V52.4 (fitting and adjustment of breast prosthesis and implant).
