Inclusion terms

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

  • Sclerocystic ovary syndrome
  • Stein-Leventhal syndrome

Other codes that can never be billed with E28.2

These codes carry an Excludes1 note pointing at E28.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E28.2 alone.

  • N83.2Other and unspecified ovarian cysts

Risk adjustment

E28.2 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.

Medicare coverage

E28.2 is named in 2 Medicare coverage policies 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

  • A53026Billing and Coding: Bariatric Surgery Coverage
  • A56421Billing and Coding: CT of the Abdomen and Pelvis
