ICD-10 code for BPH (benign prostatic hyperplasia)

The ICD-10-CM code for BPH (benign prostatic hyperplasia) is N40.0 (Benign prostatic hyperplasia without lower urinary tract symptoms). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N40.0.

It is also searched as enlarged prostate.

Within N40, choose N40.0 (without lower urinary tract symptoms) only when documentation doesn't support a more specific option: with lower urinary tract symptoms (N40.1), nodular prostate without lower urinary tract symptoms (N40.2) and nodular prostate with lower urinary tract symptoms (N40.3).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 725 (Benign Prostatic Hypertrophy with MCC, relative weight 1.1578) and DRG 726 (Benign Prostatic Hypertrophy without MCC, relative weight 0.7252), in MDC 12 (Diseases and Disorders of the Male Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
