H20.22
BillableLens-induced iridocyclitis, left eye
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is H20.22 an HCC code?
No. H20.22 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
H20.22 is the ICD-10-CM diagnosis code for lens-induced iridocyclitis, left eye. This is inflammation of the iris and ciliary body (the colored part of the eye and the muscle that controls focus) in the left eye that is caused by a problem with the eye's lens, such as a leaking or displaced lens. This condition typically develops after eye surgery or trauma involving the lens. H20.22 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).
H20.22 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 documentation specifies the left eye (H20.22) versus right eye (H20.21) or bilateral (H20.23) to ensure accurate laterality coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H20.22 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies the left eye (H20.22) versus right eye (H20.21) or bilateral (H20.23) to ensure accurate laterality coding
- •Confirm the underlying lens pathology (such as lens particle glaucoma, phacoanaphylaxis, or lens-particle glaucoma) is documented, as this may require additional coding for the primary lens condition
