ICD-10 code for urethra disorder

The ICD-10-CM code for urethra disorder is N36.9 (Urethral disorder, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N36.9.

Within N36, choose N36.9 (Urethral disorder, unspecified) only when documentation doesn't support a more specific option: urethral fistula (N36.0), urethral diverticulum (N36.1), urethral caruncle (N36.2), urethral functional and muscular disorders (N36.4), urethral false passage (N36.5) and other specified disorders of urethra (N36.8).

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.
