R34 is a billable ICD-10-CM diagnosis code for anuria and oliguria. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 673 through 675, 682 through 684. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Genitourinary signs and symptoms.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to R34: its own notes plus those printed at Chapter 18. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Notes
General instructions on how these codes are used.
- This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
- Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification. In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The residual subcategories, numbered .8, are generally provided for other relevant symptoms that cannot be allocated elsewhere in the classification.
- The conditions and signs or symptoms included in categories R00-R94 consist of:
- (a) cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated;
- (b) signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined;
- (c) provisional diagnosis in a patient who failed to return for further investigation or care;
- (d) cases referred elsewhere for investigation or treatment before the diagnosis was made;
- (e) cases in which a more precise diagnosis was not available for any other reason;
- (f) certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right.

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Anuria
absence of urine formation. it is usually associated with complete bilateral ureteral (ureter) obstruction, complete lower urinary tract obstruction, or unilateral ureteral obstruction when a solitary kidney is present.Oliguria
decreased urine output that is below the normal range. oliguria can be defined as urine output of less than or equal to 0.5 or 1 ml/kg/hr depending on the age.
Patient EducationClinical
Urine and Urination
Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate.

Questions About R34Overview
What is the ICD-10 code for anuria and oliguria?
The ICD-10-CM code for anuria and oliguria is R34. It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is R34 (Anuria and oliguria) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report anuria and oliguria on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does R34 group to?
When anuria and oliguria is the principal diagnosis on an inpatient stay, it groups to MS-DRG 674, 682, 673, 684, 683, 675, with relative weights from 0.6004 to 4.2523 depending on complications. Higher weights mean higher Medicare reimbursement.
Can R34 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the anuria and oliguria is established, that condition takes the principal position instead.
Can R34 be reported with O08.4?
Not as a rule. The Excludes1 note on R34 lists "anuria and oliguria complicating abortion or ectopic or molar pregnancy (O00-O07, O08.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
