ICD-10-CM Code Q27.8
Other specified congenital malformations of peripheral vascular system

BILLABLE
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
POA Exempt
POA Exempt Code
The 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.
| ICD-10 from 2011 - 2016

Q27.8 is a billable ICD code used to specify a diagnosis of other specified congenital malformations of peripheral vascular system. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

POA Indicators on CMS form 4010A are as follows:

IndicatorMeaningCMS Will Pay CC/MCC DRG Costs
YDiagnosis was present at time of inpatient admissionYes
NDiagnosis was not present at time of inpatient admissionNo
UDocumentation insufficient to determine if the condition was present at the time of inpatient admission.No
WClinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.Yes
1Exempt from POA reportingNo


The ICD code Q278 is used to code Aberrant subclavian artery

Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch.

Specialty: Medical Genetics
ICD 9 Code: 747.21

Normal anatomical locations of right and left subclavian arteries

Inclusion Terms
Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.

Atresia of peripheral vascular system
Congenital aneurysm (peripheral)
Congenital stricture, artery
Congenital varix
Code Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."
Arteriovenous malformation - instead, use code Q27.3-

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

Anomalies of other specified sites of peripheral vascular system (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code Q27.8 and a single ICD9 code, 747.69 is an approximate match for comparison and conversion purposes.
