What This Code Means
R34 is the ICD-10-CM diagnosis code for anuria and oliguria. A condition where a person produces little to no urine, which can indicate serious kidney or urinary system problems. R34 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving the genitourinary system (r30-r39).
R34 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Anuria (no urine output) and oliguria (very low urine output) are both included; document which condition is present if possible.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for R34 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Anuria (no urine output) and oliguria (very low urine output) are both included; document which condition is present if possible
