About coding urethral discharge
The ICD-10-CM code for urethral discharge is R36.9 (Urethral discharge, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R36.9.
Within R36, choose R36.9 (unspecified) only when documentation doesn't support a more specific option: without blood (R36.0) and Hematospermia (R36.1).
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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), 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.
