About coding ureter endometriosis
The ICD-10-CM code for ureter endometriosis is N80.A69 (Endometriosis of unspecified ureter, unspecified depth). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N80.A69.
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.
