ICD-10-CM Code Q25.4
Other congenital malformations of aorta
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
POA Exempt CodeThe Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes. This "Present On Admission" (POA) indicator is recorded on CMS form 4010A.
Q25.4 is a billable ICD code used to specify a diagnosis of other congenital malformations of aorta. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
POA Indicators on CMS form 4010A are as follows:
|Indicator||Meaning||CMS Will Pay CC/MCC DRG Costs|
|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. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.||Yes|
|1||Exempt from POA reporting||No|
The ICD code Q254 is used to code Aneurysm of sinus of Valsalva
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is comparatively rare. When present, it is usually in either the right (65-85%) or in the noncoronary (10-30%) sinus, rarely in the left (< 5%) sinus.
|ICD 9 Code:||442.9|
Aorta laid open to show the semilunar valves. (Aortic sinus, also known as "sinus of Valsalva", is labeled at upper left.)
