Anuria and oliguria (R34)
ICD-10 code R34 is used to identify conditions characterized by reduced or absent urine output, specifically anuria and oliguria. These terms describe situations where urine production is extremely low or completely stopped, which can be critical indicators in medical assessments.
R34 covers a range of conditions involving diminished urine volume, including anuria (no urine output) and oliguria (markedly reduced urine output). This code also applies when urine output is suppressed following a medical procedure, as noted by synonyms like “anuria following procedure” and “oliguria following procedure.” Healthcare professionals use this code when documenting findings such as “24 hour urine volume below reference range” or “decreased urine output,” which are important for diagnosing and managing kidney function issues and related genitourinary symptoms. Understanding the ICD-10 code for anuria and oliguria helps coders precisely capture cases involving acute renal failure or other conditions that significantly alter urine secretion.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- anuria and oliguria complicating abortion or ectopic or molar pregnancy O00 O07 O08.4
- anuria and oliguria complicating pregnancy O26.83
- anuria and oliguria complicating the puerperium O90.49
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
Ureter
One of a pair of thick-walled tubes that transports urine from the KIDNEY PELVIS to the URINARY BLADDER.
Urine
Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
