Is H52.203 an HCC code?
No. H52.203 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
H52.203 is the ICD-10-CM diagnosis code for unspecified astigmatism, bilateral. Astigmatism affecting both eyes, where both eyes have irregular corneal or lens shapes causing blurred vision. H52.203 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of ocular muscles, binocular movement, accommodation and refraction (h49-h52).
H52.203 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.
H52.203 should only be used when astigmatism is documented as bilateral and the specific type is unspecified.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H52.203 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •H52.203 should only be used when astigmatism is documented as bilateral and the specific type is unspecified
- •If documentation specifies regular or irregular astigmatism bilaterally, use the more specific bilateral codes instead
