What This Code Means
A18.15 is the ICD-10-CM diagnosis code for tuberculosis of other male genital organs. This code describes a tuberculosis infection affecting male reproductive organs other than the prostate or seminal vesicles, such as the testes, epididymis, or vas deferens. It represents an extrapulmonary form of tuberculosis that has spread to the genital tract. A18.15 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering tuberculosis (a15-a19).
A18.15 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify documentation specifies which male genital organ is affected (testis, epididymis, vas deferens, etc.) to ensure accurate coding and consider if more specific codes apply.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A18.15 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies which male genital organ is affected (testis, epididymis, vas deferens, etc.) to ensure accurate coding and consider if more specific codes apply
- •Confirm tuberculosis is confirmed (not suspected) and document whether this is drug-susceptible or drug-resistant TB, as this may affect code selection and treatment protocols
