Question 1

What is ICD-10 code Y07.510?

Accepted Answer

Y07.510 is the ICD-10-CM diagnosis code for at-home childcare provider, perpetrator of maltreatment and neglect. Maltreatment or neglect by a childcare provider who works in the victim's home, such as a nanny or in-home babysitter. Y07.510 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering assault (x92-y09).

Y07.510 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.

Distinguish between at-home childcare (Y07.510) and daycare center childcare (Y07.511) based on the location where care is provided.

Question 2

Is Y07.510 an HCC code?

Accepted Answer

No. Y07.510 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 Y07.510 billable?

Accepted Answer

Yes. Y07.510 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. Y07.510 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 Y07.510?

Accepted Answer

Y07.510 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 Y07.510 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.
