What This Code Means
H33.303 is the ICD-10-CM diagnosis code for unspecified retinal break, bilateral. Breaks or tears in the retina of both eyes without further specification of the type or location. H33.303 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).
H33.303 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.
Bilateral coding requires documentation confirming retinal breaks in both eyes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H33.303 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Bilateral coding requires documentation confirming retinal breaks in both eyes
- •Determine if breaks are the same type in both eyes or different for complete documentation
