Final answer:
When diagnosing urinary retention secondary to benign prostatic hypertrophy, the correct ICD code is a) N40.1, which represents BPH with lower urinary tract symptoms. This condition affects a significant proportion of men as they age, with treatments ranging from medication to surgery.
Step-by-step explanation:
Understanding Benign Prostatic Hyperplasia (BPH) and Urinary Retention
Benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate, can significantly impact urinary function in men. The condition often leads to urinary retention, where there's a difficulty in passing urine due to the constriction of the urethra. This is primarily a result of the enlarged prostate pressing against the urinary passage. Understanding the appropriate diagnosis code is essential for accurate medical records and treatment. Given the information that the urinary retention is secondary to benign prostatic hypertrophy, the most fitting International Classification of Diseases (ICD) code for this diagnosis would be: a) N40.1 which stands for benign prostatic hyperplasia with lower urinary tract symptoms.
By age 60, nearly 40 percent of men experience some degree of BPH, and this number increases to up to 80 percent by age 80. The primary goal of BPH treatment is to alleviate the pressure on the urethra, allowing for more typical urine flow. Mild to moderate symptoms can be managed with medication, while more severe cases may require surgical intervention to remove a portion of the prostate tissue.
