R33.9
ICD-10-CMThis code signifies the inability to completely empty the bladder, where the underlying cause is not specified. It describes a general state of urinary retention without further detail regarding its etiology, such as obstruction, neurogenic bladder, or medication effects.
Use this code when documentation indicates urinary retention but lacks specific information about the type or cause. This is appropriate when the physician's diagnosis is simply "urinary retention" without further clarification or when the etiology is still under investigation.
