Three necessary components to bill a pharmacy claim are Member ID number, BIN, and PCN.
- Member ID number: This is the patient's unique identifier within their insurance plan.
- BIN: This is the Bank Identification Number, which is a unique identifier for the insurance company.
- PCN: This is the Pharmacy Contract Number, which is a unique identifier for the pharmacy.
These three components are essential for accurately and efficiently billing pharmacy claims. Without them, the insurance company may not be able to process the claim, or the patient may be responsible for the full cost of the prescription.
