ICD-10-CM Code Q27.8

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.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.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:
| 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 |
