Question 1

What is ICD-10 code O09.812?

Accepted Answer

O09.812 is the ICD-10-CM diagnosis code for supervision of pregnancy resulting from assisted reproductive technology, second trimester. Medical supervision of a pregnancy that resulted from assisted reproductive technology (such as IVF or fertility treatments) during the second three months of pregnancy. O09.812 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering supervision of high risk pregnancy (o09).

O09.812 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.

Document the specific trimester dates and continue monitoring for complications associated with assisted reproductive pregnancies.

Question 2

Is O09.812 an HCC code?

Accepted Answer

No. O09.812 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 O09.812 billable?

Accepted Answer

Yes. O09.812 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. O09.812 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 O09.812?

Accepted Answer

O09.812 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 O09.812 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 O09.812?

Accepted Answer

Document the specific trimester dates and continue monitoring for complications associated with assisted reproductive pregnancies. Pair with other relevant pregnancy codes to capture the complete clinical picture of the high-risk pregnancy.
