Q24.0

Q24.0 — Dextrocardia

Billable / specific codeICD-10-CMPOA exempt

Q24.0 is a billable, specific ICD-10-CM code for dextrocardia. It is valid for submission on a claim.

Excludes1 — never code together

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

dextrocardia with situs inversus (Q89.3)
isomerism of atrial appendages (with asplenia or polysplenia) (Q20.6)
mirror-image atrial arrangement with situs inversus (Q89.3)

Other codes that can never be billed with Q24.0

These codes carry an Excludes1 note pointing at Q24.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q24.0 alone.

Q89.3Situs inversus

Risk adjustment

Q24.0 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

Q24.0 is named in 21 Medicare coverage policies — 21 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
