Is H10.532 an HCC code?
No. H10.532 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
H10.532 is the ICD-10-CM diagnosis code for contact blepharoconjunctivitis, left eye. This is an inflammation of the eyelid and the clear membrane covering the white part of the eye (conjunctiva) on the left eye, caused by contact with an irritating substance or allergen. It results in redness, swelling, and discomfort of the affected eye. H10.532 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of conjunctiva (h10-h11).
H10.532 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 laterality is documented as left eye in the medical record before assigning this code; if bilateral, code both eyes separately with appropriate laterality indicators.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H10.532 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as left eye in the medical record before assigning this code; if bilateral, code both eyes separately with appropriate laterality indicators
- •Ensure the documentation specifies contact blepharoconjunctivitis rather than other types of conjunctivitis (allergic, infectious, viral) to avoid incorrect code selection
