Bladder neck obstruction

This code represents a blockage at the outlet of the bladder, specifically at the junction where the bladder connects to the urethra. This obstruction can impede the flow of urine, leading to various urinary symptoms and potential complications.

Use this code when documentation clearly indicates a diagnosis of bladder neck obstruction, regardless of its underlying cause (e.g., benign prostatic hyperplasia, primary bladder neck dysfunction, stricture). Supporting documentation should include physician notes detailing the obstruction and its location.

• Differentiate from urethral stricture (598.0) or prostatic obstruction (600.0x) unless the bladder neck itself is the primary site of obstruction.
• Always look for documentation of the underlying cause of the bladder neck obstruction, if known, to code it additionally.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
