Question 1

What is ICD-10 code A06.7?

Accepted Answer

A06.7 is the ICD-10-CM diagnosis code for cutaneous amebiasis. This is a skin infection caused by parasitic amoebas that enter through breaks in the skin, typically occurring in tropical or subtropical regions. The infection causes ulcers, sores, or lesions on the skin surface. A06.7 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering intestinal infectious diseases (a00-a09).

A06.7 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 the diagnosis is specifically cutaneous (skin) amebiasis and not intestinal or hepatic amebiasis, as each has different codes.

Question 2

Is A06.7 an HCC code?

Accepted Answer

No. A06.7 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 A06.7 billable?

Accepted Answer

Yes. A06.7 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. A06.7 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 A06.7?

Accepted Answer

A06.7 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 model rewards A06.7 with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's RAF score in either version. Coders should check whether provider documentation supports a more specific child code that does map to a payment HCC.

Question 5

What should coders know when reporting A06.7?

Accepted Answer

Verify the diagnosis is specifically cutaneous (skin) amebiasis and not intestinal or hepatic amebiasis, as each has different codes Document the anatomical location of the skin lesions when possible, as this may support medical necessity and treatment decisions
