Question 1

What is ICD-10 code H44.623?

Accepted Answer

H44.623 is the ICD-10-CM diagnosis code for retained (old) magnetic foreign body in iris or ciliary body, bilateral. Magnetic foreign objects that have been retained in the iris or ciliary body of both eyes for an extended period. H44.623 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of vitreous body and globe (h43-h44).

H44.623 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.

Bilateral iris or ciliary body involvement is uncommon; ensure documentation supports this diagnosis.

Question 2

Is H44.623 an HCC code?

Accepted Answer

No. H44.623 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 H44.623 billable?

Accepted Answer

Yes. H44.623 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. H44.623 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

Which HCC does H44.623 map to under V28?

Accepted Answer

H44.623 does not map to a CMS-HCC V28 payment category. Check the current CMS-HCC V28 model file for payment year 2026 rather than an older V24 tip sheet.

Question 5

What does H44.623 pay in RAF?

Accepted Answer

H44.623 has no separately stated V28 community RAF weight. If it is not a V28 payment HCC, it adds nothing to a community RAF score.

Question 6

What is the V28 vs V24 difference for H44.623?

Accepted Answer

H44.623 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 H44.623 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 7

What documentation supports H44.623?

Accepted Answer

Bilateral iris or ciliary body involvement is uncommon; ensure documentation supports this diagnosis Confirm both eyes are affected at this specific anatomical location before coding H44.623 is not a CMS-HCC payment code, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.
