Question 1

What is ICD-10 code N53.8?

Accepted Answer

N53.8 is the ICD-10-CM diagnosis code for other male sexual dysfunction. Sexual dysfunction in males that is not related to erectile function or ejaculation, such as reduced sexual desire or orgasmic disorders. N53.8 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering diseases of male genital organs (n40-n53).

N53.8 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.

This code encompasses male sexual dysfunction beyond erectile and ejaculatory issues; clearly document the specific dysfunction.

Question 2

Is N53.8 an HCC code?

Accepted Answer

No. N53.8 is a billable ICD-10-CM code but does not map to any payment HCC category under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can still be reported on Medicare Advantage encounter data submissions, but it does not contribute to the beneficiary's Risk Adjustment Factor (RAF) score and therefore does not affect the risk-adjusted capitation payment to the plan. V28 reached 100% phase-in for payment year 2026.

Question 3

Is N53.8 billable?

Accepted Answer

Yes. N53.8 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. N53.8 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Question 4

What is the V28 vs V24 difference for N53.8?

Accepted Answer

N53.8 does not map to a payment HCC under either the CMS-HCC V28 risk adjustment model or the older V24 model. V28 reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Because neither community model rewards N53.8 with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's V28/V24 community RAF score in either version. Coders should check whether provider documentation supports a more specific child code that does map to a community payment HCC.

Question 5

What should coders know when reporting N53.8?

Accepted Answer

This code encompasses male sexual dysfunction beyond erectile and ejaculatory issues; clearly document the specific dysfunction Review the medical record to ensure the condition is not better classified under N52 (erectile) or N53.1 (ejaculatory) categories
