Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • central serous chorioretinopathy (H35.71-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Retinal detachment NOS
  • Retinal detachment without retinal break

Other codes that can never be billed with H33.2

These codes carry an Excludes1 note pointing at H33.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H33.2 alone.

  • H33.0Retinal detachment with retinal break
  • H35.7Separation of retinal layers

Risk adjustment

H33.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead H33.2
