Z43.6Encounter for attention to other artificial openings of urinary tract

Z43.6 is the ICD-10-CM diagnosis code for encounter for attention to other artificial openings of urinary tract. It belongs to category Z43 (encounter for attention to artificial openings), 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 Z43, choose Z43.6 (other artificial openings of urinary tract) only when documentation doesn't support a more specific option: tracheostomy (Z43.0), gastrostomy (Z43.1), ileostomy (Z43.2), colostomy (Z43.3), other artificial openings of digestive tract (Z43.4), cystostomy (Z43.5), artificial vagina (Z43.7), other artificial openings (Z43.8) and 1 more.

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 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 V55.6 (attention to other artificial opening of urinary tract).
