Is H40.841 an HCC code?
H40.841 has no mapping under the current CMS-HCC V28 community payment model. H40.841 has a separate mapping under the Part D RxHCC model (HCC 243 (Glaucoma, Open-Angle or Moderate/Severe Stage)); the applicable result needs member context.

HCC Category Mapping
These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for H40.841
For H40.841, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means
H40.841 is the ICD-10-CM diagnosis code for neovascular secondary angle closure glaucoma, right eye. A type of glaucoma in the right eye caused by abnormal blood vessel growth that blocks fluid drainage and increases eye pressure. H40.841 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering glaucoma (h40-h42).
H40.841 has no mapping under the current CMS-HCC V28 community payment model. H40.841 has a separate mapping under the Part D RxHCC model (HCC 243 (Glaucoma, Open-Angle or Moderate/Severe Stage)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.
This is a secondary glaucoma; ensure documentation indicates neovascularization as the underlying cause.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H40.841 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a secondary glaucoma; ensure documentation indicates neovascularization as the underlying cause
- •Verify the laterality is specifically documented as right eye before assigning this code
