Third-Party Billing and Insurance
- Identify the standardized electronic routing identifiers and data fields required to submit third-party prescription claims.
- Differentiate cost-sharing terms, reimbursement structures, formulary tiers, and major government health programs.
- Resolve common claim adjudications and rejections within the pharmacy technician scope of practice under pharmacist supervision.
Claim Transmission Standards and Cardholder Identification
In modern community practice, billing for prescription medications occurs almost entirely through electronic data interchange. The National Council for Prescription Drug Programs establishes standardized electronic formats for pharmacy claim transmission, ensuring that pharmacy management software can communicate reliably with diverse payers. Under the supervision of a licensed pharmacist, pharmacy technicians are responsible for entering third-party billing information into the pharmacy management system. Accurately entering this data ensures that the claim reaches the right payer and adjudicates without administrative errors.
To route a prescription claim to the proper payer, the technician must locate specific routing numbers on the patient's insurance card. The Bank Identification Number is a six-digit number used by pharmacy software to route prescription claims to the correct third-party processor. In addition to this six-digit number, pharmacy benefit managers frequently require a Processor Control Number. The Processor Control Number is a secondary identifier used by pharmacy benefit managers to direct claims to specific benefit plans. The BIN and PCN help route the claim to the appropriate processor, while the group number and member information, when required, help identify the patient's specific benefit plan and coverage.
The insurance card also contains essential member credentials that identify who is covered. The member ID identifies the covered subscriber or member, but multiple family members may share this primary number. When dependents share a subscriber ID, they are distinguished by a person code, which indicates the specific family member covered under the cardholder's insurance policy. If coverage is sponsored through an employer or specific organization, the card will display a group number. The group number identifies the employer group, organization, or benefit plan associated with the patient's coverage, when a group number applies.
Finally, every prescription claim submitted through the pharmacy management system includes specific product and provider information. The National Drug Code submitted on a pharmacy claim identifies the labeler, drug product, and package size dispensed. In addition, pharmacy claims generally include the prescriber's National Provider Identifier to identify the prescriber. It is important to note that a National Provider Identifier identifies the provider, but it does not, by itself, verify licensure. While technicians enter these identifiers, the pharmacist performs the required clinical review and final verification of the dispensed prescription.
Common mistakes
- Assuming an 'NDC not covered' rejection means the medication entity is entirely excluded from the plan, rather than checking if an alternative National Drug Code for the drug is covered.
- Providing clinical justifications to an insurance company or prescriber during a prior authorization request, which exceeds the technician's scope of practice.
- Applying the birthday rule by comparing the chronological ages of the parents rather than whose birthday occurs earlier in the calendar year.
- Entering a Submission Clarification Code simply to bypass an adjudication rejection without ensuring that payer rules are satisfied and documentation is present, which can constitute fraudulent billing.
Key points
- Third-party claims are transmitted via standardized NCPDP formats using six-digit Bank Identification Numbers to reach processors, Processor Control Numbers to direct claims to specific plans, and member IDs, person codes, and group numbers to identify beneficiaries.
- Formulary tier assignments vary by plan; low-cost generics often occupy the lowest tier, while preferred brands, nonpreferred drugs, and specialty products may be assigned to higher tiers.
- Patient cost sharing includes copayments, coinsurance, and deductibles; an out-of-pocket maximum limits spending only for costs to which that plan limit applies, while a Maximum Allowable Cost may limit reimbursement for the ingredient cost of certain multisource drugs.
- Medicare covers medical services across Part A (inpatient), Part B (outpatient medical care, vaccines, and durable medical equipment billed using HCPCS codes), and Part D (prescription drugs), with Medicaid acting as payer after other liable third-party coverage.
- Under coordination of benefits, primary plans pay before secondary plans, and the birthday rule designates the primary plan for a dependent child based on which parent's birthday falls earlier in the calendar year.
- Pharmacy technicians may resolve administrative rejections and initiate prior-authorization tasks under pharmacist supervision; the prescriber or pharmacist supplies clinical justification as appropriate, while the pharmacist handles clinical assessment, patient counseling, and final verification.
