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.Q79.8 is a billable ICD code used to specify a diagnosis of other congenital malformations of musculoskeletal 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 |
The ICD code Q798 is used to code Poland syndrome
Poland syndrome (also Poland's syndrome, Poland's syndactyly, Poland sequence, and Poland's anomaly) is a rare birth defect characterized by underdevelopment or absence of the chest muscle (pectoralis) on one side of the body, and usually also webbing of the fingers (cutaneous syndactyly) of the hand on the same side (the ipsilateral hand). In most affected individuals, the missing part is the large section of the muscle that normally attaches to the upper arm on one side and the breastbone (sternum) on the other. Other abnormalities may occur on the affected side of the torso. In some cases, additional muscles in the chest wall, side, and shoulder are missing or underdeveloped.
