About N80.A69

N80.A69 is the ICD-10-CM diagnosis code for endometriosis of unspecified ureter, unspecified depth. It belongs to category N80 (endometriosis), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N80.A6, choose N80.A69 (unspecified ureter, unspecified depth) only when documentation doesn't support a more specific option: right ureter, unspecified depth (N80.A61), left ureter, unspecified depth (N80.A62) and bilateral ureters, unspecified depth (N80.A63).

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 on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It was added in FY2023, effective October 1, 2022.
