What This Code Means
H20.032 is the ICD-10-CM diagnosis code for secondary infectious iridocyclitis, left eye. This is an 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 an infection elsewhere in the body. The infection has spread to or triggered inflammation in the eye structures. H20.032 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).
H20.032 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.
Always verify the laterality is documented as left eye; 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 H20.032 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Always verify the laterality is documented as left eye; if bilateral, code both eyes separately with appropriate laterality indicators
- •Identify and code the underlying infectious cause (such as tuberculosis, syphilis, or other systemic infections) as the primary diagnosis, as this is a secondary condition
