Bladder-neck obstruction

This code signifies an acquired narrowing or blockage at the outlet of the bladder, preventing or impeding the normal flow of urine. This obstruction can be caused by various factors, leading to symptoms such as urinary hesitancy, weak stream, incomplete emptying, and urinary retention.

Assign this code when documentation specifies an acquired obstruction of the bladder neck, often identified through imaging studies or cystoscopy. This diagnosis is commonly associated with conditions like benign prostatic hyperplasia (BPH) in males, or bladder neck hypertrophy in females.

• Differentiate from congenital bladder-neck obstruction (Q64.3-), which is an Excludes1 condition.
• Look for documentation specifying the cause of the obstruction, if known, to determine if an additional code is necessary.
• Consider sequencing if the bladder-neck obstruction is a manifestation of another underlying condition.
