2021 ICD-10-CM Code Q24.5
Malformation of coronary vessels
Valid for Submission
Q24.5 is a billable diagnosis code used to specify a medical diagnosis of malformation of coronary vessels. The code Q24.5 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code Q24.5 might also be used to specify conditions or terms like aberrant course of left anterior descending coronary artery from right coronary artery crossing right ventricular outflow tract, abnormal coronary artery course, abnormal ostium of coronary artery, abnormal ostium of coronary sinus, abnormality of right superior vena cava , aneurysm of coronary vessels, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code Q24.5 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.
Present on Admission (POA)
Q24.5 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here .
CMS POA Indicator Options and Definitions
POA Indicator Code | POA Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |
Convert Q24.5 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code Q24.5 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Congenital Heart Defects
A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely.
Doctors use a physical exam and special heart tests to diagnose congenital heart defects. They often find severe defects during pregnancy or soon after birth. Signs and symptoms of severe defects in newborns include
- Rapid breathing
- Cyanosis - a bluish tint to the skin, lips, and fingernails
- Fatigue
- Poor blood circulation
Many congenital heart defects cause few or no signs and symptoms. They are often not diagnosed until children are older.
Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.
