About R39.2

R39.2 is the ICD-10-CM diagnosis code for Extrarenal uremia. 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 (other and unspecified symptoms and signs involving the genitourinary system), R39.2 is specifically for Extrarenal uremia. Related codes cover Extravasation of urine (R39.0), other difficulties with micturition (R39.1), other symptoms and signs involving the genitourinary system (R39.8) and unspecified symptoms and signs involving the genitourinary system (R39.9).

Don't report R39.2 together with the conditions in its Excludes1 note: uremia NOS (N19).

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 788.99 (other symptoms involving urinary system).
