Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Ectopia Cordis
a rare developmental defect in which the heart is abnormally located partially or totally outside the thorax. it is the result of defective fusion of the anterior chest wall. depending on the location of the heart, ectopia cordis can be thoracic, thoracoabdominal, abdominal, and cervical.Cardiomegaly
enlargement of the heart, usually indicated by a cardiothoracic ratio above 0.50. heart enlargement may involve the right, the left, or both heart ventricles or heart atria. cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (heart failure) or several forms of cardiomyopathies.Cardiomegaly, Exercise-Induced
non-pathological heart enlargement and other remodeling in cardiac morphology and electrical circuitry found in individuals who participate in intense repeated exercises.Thorax
the upper part of the trunk between the neck and the abdomen. it contains the chief organs of the circulatory and respiratory systems. (from stedman, 25th ed)Thoracodidymus
conjoined twins united at the thorax.Congenital Diaphragmatic Hernia
diaphragmatic hernia that is present at birth.Bilateral Renal Agenesis
a congenital abnormality characterized by the absence of both kidneys.Renal Agenesis
a congenital abnormality characterized by the absence of one or both kidneys.Unilateral Renal Agenesis|Congenital Single Kidney|Congenital Solitary Kidney|Congenital Solitary Kidney
a congenital abnormality characterized by the presence of only one kidney.Pericardial Anomaly
any abnormality involving the pericardium.Horseshoe Kidney
a congenital abnormality in which the two kidneys fuse together during fetal development to create a horseshoe-shaped structure.Coenzyme Q10 Deficiency
a genetically heterogeneous condition, typically inherited in an autosomal recessive fashion, characterized by coenzyme q10 deficiency.Ectopia Cordis
a rare congenital anomaly where the heart is formed outside of the thoracic cavity. it is associated with intracardiac lesions and other structural malformations.Externalized Heart|EXTERNALIZED HEART|Ectopia Cordis|Exocardia
a type of exocardia in which the heart develops outside of the body.
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.

Code HistoryHistory
Questions About Q24.8Overview
Is Q24.8 (Other congenital malformations of heart) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified congenital malformations of heart on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does Q24.8 group to?
When other specified congenital malformations of heart is the principal diagnosis on an inpatient stay, it groups to MS-DRG 306, 307, with relative weights from 0.9132 to 1.5758 depending on complications. Higher weights mean higher Medicare reimbursement.
Is Q24.8 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 other specified congenital malformations of heart on inpatient claims.
What is the ICD-9 equivalent of Q24.8?
Under the General Equivalence Mappings, other specified congenital malformations of heart converts to ICD-9-CM 746.84 (obstruct heart anom NEC), 746.87 (malposition of heart), and 746.89 (cong heart anomaly NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:
- The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
- The condition places limitations on self-care, independent living, and social interactions.
