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.Q74.1 is a billable ICD code used to specify a diagnosis of congenital malformation of knee. 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 Q741 is used to code Genu valgum
Genu valgum, commonly called "knock-knee", is a condition in which the knees angle in and touch one another when the legs are straightened. Individuals with severe valgus deformities are typically unable to touch their feet together while simultaneously straightening the legs. The term originates from the Latin genu, "knee", and valgus which actually means bent outwards, but in this case, it is used to describe the distal portion of the knee joint which bends outwards and thus the proximal portion seems to be bent inwards. For citation and more information on uses of the words Valgus and Varus, please visit the internal link to -varus.
