ICD-10 code for bladder endometriosis

The ICD-10-CM code for bladder endometriosis is N80.A0 (Endometriosis of bladder, unspecified depth). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N80.A0.

Within N80.A, choose N80.A0 (Endometriosis of bladder, unspecified depth) only when documentation doesn't support a more specific option: superficial endometriosis of bladder (N80.A1), deep endometriosis of bladder (N80.A2), superficial endometriosis of ureter (N80.A4), deep endometriosis of ureter (N80.A5) and endometriosis of ureter, unspecified depth (N80.A6).

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.
