About R39.191

R39.191 is the ICD-10-CM diagnosis code for Need to immediately re-void. It belongs to category R39 (other and unspecified symptoms and signs involving the genitourinary system), 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 R39.19 (other difficulties with micturition), R39.191 is specifically for Need to immediately re-void. Related codes cover position dependent micturition (R39.192) and other difficulties with micturition (R39.198).

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 was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 788.69 (other abnormality of urination).
