Use STC Codes

The first element of all STC segments, STC01, is named Health care status claim. Field STC01 is a composite field that holds several code values. Consider the following snippet:

```javascript
    STC*F1:65:1E*
```

This is the first part of the substantial STC segment. In a composite field, the colon (:) is used as a separator to isolate each coding value. It is another use of the composite element delimiter.

Field	Description
First sub-field, (`F1`)	Health Care Claim Status Category code. Here, the code indicates the claim or service line item is Finalized and Paid (Finalized/Paid). This list is publicly available and is not published in the Implementation Guide.
Second sub-field, (`65`)	Claim Status Code. This code is added by the adjudication authority. The value shown also indicates the claim item is Paid. This list is publicly available and is not published in the Implementation Guide.
Third sub-field (`1E`)	Entity identifier; here, it shows that the payment is coming from an HMO. The code defines the context for the previous two values, and comes from a substantial code list (see page 161 through 167 of the ASC X12 276/277 Implementation Guide).
