Atrophy of prostate

This code describes a reduction in the size and mass of the prostate gland due to a decrease in cell size or number. It signifies a non-hyperplastic, degenerative change in the prostate, often associated with aging or hormonal imbalances.

Apply this code when documentation explicitly states "prostatic atrophy" or "atrophy of the prostate." This diagnosis is typically made based on imaging studies (e.g., ultrasound, MRI) or histological findings from a biopsy.

• Differentiate from prostatic hypoplasia, which refers to incomplete development rather than shrinkage of previously normal tissue.
• Do not use for benign prostatic hyperplasia (BPH), which is an enlargement of the prostate.
• Consider any underlying causes documented, such as hormonal deficiencies, and code them as secondary diagnoses if applicable.
