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.Q04.3 is a billable ICD code used to specify a diagnosis of other reduction deformities of brain. 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 |

The ICD code Q043 is used to code Pachygyria
Pachygyria (from the Greek "pachy" meaning "thick" or "fat" gyri) is a congenital malformation of the cerebral hemisphere. It results in unusually thick convolutions of the cerebral cortex. Typically, children have developmental delay and seizures, the onset and severity depending on the severity of the cortical malformation. Infantile spasms are common in affected children, as is intractable epilepsy.
