What Is Third-Party Billing
Third-party billing is the process of submitting prescription claims to insurance companies for payment. The "third party" is the insurance plan, with the patient being the first party and the pharmacy the second party. This is a major part of daily pharmacy operations and appears on the PTCE in the Order Entry and Processing domain.
Key Billing Terms
- Copay - the fixed amount the patient pays at the point of sale
- Deductible - the amount the patient must pay before insurance begins covering costs
- Formulary - the list of medications covered by an insurance plan
- Prior authorization - insurance requirement for prescriber approval before coverage
- Adjudication - the process of submitting and processing an insurance claim
Common Rejection Reasons
Insurance claims can be rejected for many reasons:
- Refill too soon - the patient is trying to fill before the previous supply should be exhausted
- Drug not covered - the medication is not on the plan's formulary
- Prior authorization required - the plan requires prescriber approval
- Invalid days supply - the calculated days supply does not match the quantity
- Patient not eligible - coverage has lapsed or the patient is not enrolled
The Technician's Role in Billing
Pharmacy technicians handle much of the daily billing work: entering insurance information, submitting claims, troubleshooting rejections, contacting insurance companies for overrides, and explaining costs to patients. Strong billing skills make technicians valuable to employers.
Exam Tips
For the PTCE, understand common rejection types and their general resolutions. Know basic billing terminology and the role of formularies in determining coverage. Questions may present billing scenarios and ask you to identify the likely rejection reason or the appropriate next step.
