Calculus of prostate

This code signifies the presence of prostatic calculi, which are calcifications or stones found within the prostate gland. These stones can be endogenous (formed within the prostate) or exogenous (migrated from the urinary tract). While often asymptomatic, they can contribute to symptoms such as chronic pelvic pain, recurrent urinary tract infections, or obstructive voiding.

Use this code when documentation clearly indicates the diagnosis of prostatic calculi, regardless of whether they are causing symptoms. This diagnosis is typically supported by imaging studies such as transrectal ultrasound (TRUS), CT scans, or MRI of the prostate, or by direct visualization during surgical procedures.

• Do not confuse prostatic calculi with kidney stones (nephrolithiasis) or bladder stones (cystolithiasis).
• If the calculi are causing an obstruction, code the obstruction separately if specified, and sequence accordingly.
• Ensure the documentation specifies "prostate" to differentiate from calculi in other parts of the genitourinary system.
