Retention of urine (R33)

The ICD-10 code section R33 covers the condition known as retention of urine, which involves difficulty or inability to empty the bladder fully. This section includes specific codes for different causes and types of urinary retention.

The main code, R33, represents general retention of urine. More detailed codes help healthcare professionals specify the cause: R33.0 is used when urine retention is caused by medications, often called drug-induced retention of urine. The code R33.8 includes various forms of retention such as incomplete bladder emptying due to benign prostatic hypertrophy, postoperative or postprocedural retention, and occlusion of a Foley catheter. Lastly, R33.9 applies when the exact cause is unspecified but the patient shows symptoms such as inefficient bladder emptying or large residual urine volume. These codes assist medical coders and caregivers in precisely documenting conditions like acute or chronic urinary retention, Fowler syndrome, and cauda equina syndrome-related painless retention, ensuring accurate ICD-10 code selection for retention of urine diagnoses.
