Other codes that can never be billed with Q89.3

Q20Congenital malformations of cardiac chambers and connections
Q24.0Dextrocardia

Risk adjustment

Q89.3 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

Q89.3 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
