About Z46.6

Z46.6 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of urinary device. It belongs to category Z46 (encounter for fitting and adjustment of other devices), 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 Z46 (encounter for fitting and adjustment of other devices), Z46.6 is specifically for encounter for fitting and adjustment of urinary device. Related codes cover spectacles and contact lenses (Z46.0), hearing aid (Z46.1), related to nervous system and special senses (Z46.2), dental prosthetic device (Z46.3), orthodontic device (Z46.4), other gastrointestinal appliance and device (Z46.5), other specified devices (Z46.8) and unspecified device (Z46.9).

The conditions in its Excludes2 note aren't part of Z46.6, but may be coded alongside it if the patient has both: attention to artificial openings of urinary tract (Z43.5, Z43.6).

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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 V53.6 (fitting and adjustment of urinary devices).
