What This Code Means
H00.11 is the ICD-10-CM diagnosis code for chalazion right upper eyelid. A small, non-infected cyst (chalazion) in the right upper eyelid, typically caused by blocked oil glands and appearing as a painless bump. H00.11 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of eyelid, lacrimal system and orbit (h00-h05).
H00.11 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 chalazion from hordeolum (stye), which is infected and painful; chalazion is usually painless.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H00.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish chalazion from hordeolum (stye), which is infected and painful; chalazion is usually painless
- •Confirm right eye and upper eyelid location in documentation
