A18.14Tuberculosis of prostate

A18.14 is the ICD-10-CM diagnosis code for tuberculosis of prostate. It belongs to category A18 (tuberculosis of other organs), block A15-A19 (tuberculosis) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within A18.1 (tuberculosis of genitourinary system), A18.14 is specifically for tuberculosis of prostate. Related codes cover unspecified (A18.10), tuberculosis of kidney and ureter (A18.11), tuberculosis of bladder (A18.12), tuberculosis of other urinary organs (A18.13), tuberculosis of other male genital organs (A18.15), tuberculosis of cervix (A18.16), tuberculous female pelvic inflammatory disease (A18.17) and tuberculosis of other female genital organs (A18.18).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 727 (Inflammation of the Male Reproductive System with MCC, relative weight 1.37), DRG 728 (Inflammation of the Male Reproductive System without MCC, relative weight 0.8224), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 12 (Diseases and Disorders of the Male Reproductive System) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 016.50 (tuberculosis of other male genital organs, unspecified), 016.50 (tuberculosis of other male genital organs, unspecified) and 601.4 (prostatitis in diseases classified elsewhere).
