ICD-10-CM Code For Other And Unspecified Disorders Of Prostate: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N42 includes other and unspecified disorders of the prostate, covering nonneoplastic inflammatory, obstructive, or functional prostate conditions that are not classified elsewhere. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving prostate symptoms, inflammation, or dysfunction, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM N42 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM N42: Other And Unspecified Disorders Of Prostate Overview

The ICD-10-CM N42 group includes codes for other and unspecified prostate disorders that do not fit into more specific prostate disease categories. These diagnoses target the male reproductive system, specifically nonneoplastic prostate conditions such as chronic or acute inflammatory and functional prostate disorders. Accurate coding ensures complete clinical documentation and supports appropriate reimbursement processes.

When to Use

Use a code from this group when a patient has a documented prostate disorder that is inflammatory, obstructive, or functional but does not meet criteria for a more specific prostate diagnosis. These codes are appropriate when clinical documentation describes prostate symptoms or findings without a definitive, separately coded neoplastic diagnosis.

DRG Codes

DRG Code	Description
725	Benign Prostatic Hypertrophy with MCC
726	Benign Prostatic Hypertrophy without MCC
729	Other Male Reproductive System Diagnoses with CC/MCC
730	Other Male Reproductive System Diagnoses without CC/MCC

Typical Clinical Scenarios

A 68-year-old man presents to primary care with months of progressive urinary hesitancy, weak stream, nocturia, and incomplete bladder emptying. On digital rectal exam the prostate is mildly enlarged and urinalysis is negative for infection; uroflowmetry shows obstructive pattern consistent with bladder outlet obstruction from prostate enlargement. A diagnosis from this group is assigned to capture symptomatic obstructive prostate disease managed conservatively or with referral to urology. Typical codes: N42.0, N42.1
A 55-year-old male arrives at the emergency department with sudden onset severe perineal and pelvic pain, fever, and urinary retention. Imaging and exam suggest acute prostatitis with focal prostatic abscess requiring drainage and intravenous antibiotics; the presentation is an acute, infective complication of the prostate. A code from this group is used to document the acute inflammatory or abscess-forming prostate disorder as the principal reason for care. Typical codes: N42.1, N42.31
A 74-year-old man with long-standing lower urinary tract symptoms and prior transurethral resection of the prostate presents for routine follow-up and reports persistent nocturia and recurrent urinary tract infections; evaluation finds chronic pelvic pain and prostatic pain syndrome without clear infection. A chronic, noninfectious or unspecified prostate disorder code from this group is assigned to reflect ongoing prostate-related symptoms and to track as a comorbidity affecting management. Typical codes: N42.83, N42.9
