R36.0Urethral discharge without blood

R36.0 is the ICD-10-CM diagnosis code for urethral discharge without blood. It belongs to category R36 (urethral discharge), block R30-R39 (symptoms and signs involving the genitourinary system) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R36, choose R36.0 (without blood) only when documentation doesn't support a more specific option: Hematospermia (R36.1) and unspecified (R36.9).

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 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 788.7 (urethral discharge).
