- Billable — Valid for Submission
- CC — Complication or Comorbidity
- POA Exempt
- Chronic Condition
Q24.0 is a billable ICD-10-CM diagnosis code for dextrocardia. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 306 through 307. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 53 closely related codes. The code is exempt from POA reporting. Coders also document this condition as congenital malposition of heart. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Cardiac and circulatory congenital anomalies.

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Dextrocardia
a congenital defect in which the heart is located on the right side of the thorax instead of on the left side (levocardia, the normal position). when dextrocardia is accompanied with inverted heart atria, a right-sided stomach, and a left-sided liver, the combination is called dextrocardia with situs inversus. dextrocardia may adversely affect other thoracic organs.
Patient EducationClinical
Congenital Heart Defects
Congenital heart defects (CHDs) are problems with the structure of the heart. "Congenital" means that that the problems are present at birth. These defects happen when a fetus's heart doesn't develop normally during pregnancy. Congenital heart defects are the most common type of birth defect.

Questions About Q24.0Overview
What is the ICD-10 code for dextrocardia?
The ICD-10-CM code for dextrocardia is Q24.0 (sometimes written as Q240). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Q24.0 (Other congenital malformations of heart) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report dextrocardia on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q24.0 group to?
When dextrocardia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 306, 307, with relative weights from 0.9146 to 1.5457 depending on complications. Higher weights mean higher Medicare reimbursement.
Is Q24.0 a CC or MCC?
CMS lists Q24.0 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 53 closely related codes in its exclusion list.
Is Q24.0 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for dextrocardia on inpatient claims. The code appears in the Congenital malformations of the circulatory system (Q20-Q28) range of the CMS exempt list.
