What This Code Means
H33.23 is the ICD-10-CM diagnosis code for serous retinal detachment, bilateral. Fluid accumulation beneath the retina in both eyes causing the retina to separate from the back of the eye. H33.23 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).
H33.23 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 explicit documentation that both eyes are affected.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H33.23 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Bilateral coding requires explicit documentation that both eyes are affected
- •Do not assume bilateral involvement; code only what is documented
