About coding urethra sacculation
The ICD-10-CM code for urethra sacculation is N36.1 (Urethral diverticulum).
Within N36 (other disorders of urethra), N36.1 is specifically for urethral diverticulum. Related codes cover urethral fistula (N36.0), urethral caruncle (N36.2), urethral functional and muscular disorders (N36.4), urethral false passage (N36.5), other specified disorders of urethra (N36.8) and urethral disorder, unspecified (N36.9).
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.
