Chapter 6: Insurance and Third Party Billing

Medication Reconciliation

  • Medication Reconciliation: A critical and formalized process intended to prevent medication errors by ensuring there is complete and accurate consistency between a patient’s current medications (including over-the-counter and supplements) and all new or existing medical orders. This process is vital at transitions of care (admission, transfer, discharge), as it significantly reduces adverse drug events.

  • Role of Pharmacy Technicians: Pharmacy technicians are crucial in compiling comprehensive, accurate lists of patients’ medications for clinical decision-making by pharmacists and prescribers. They also verify this information through multiple reliable sources, such as patient interviews, pharmacy records, and physician offices, to ensure accuracy, thereby minimizing medication discrepancies and potential harm.

Scenario-Based Application

  • As a pharmacy technician at Stepful Community Pharmacy, you will assist patients with medication reconciliation, specifically in accurately completing the 'best possible medication history' part of the medication reconciliation form by gathering detailed information about each medication.

Example: Medication Reconciliation Form

  • Patient Details:

    • Name: Jane Doe

    • Date of Birth: 7/21/76

    • ID: AB12485

    • Medication Allergies: Penicillin (documented reactions: hives, swelling of lips and tongue, wheezing)

  • Best Possible Medication History:

    • Medication Name:

    • Lisinopril, 10 mg, Oral, Daily, Prescribed by Dr. Jones (for hypertension)

    • Acetaminophen, 250 mg, Oral, 4x Daily, Prescribed by Dr. Cain (for chronic pain)

    • Atorvastatin, 40 mg, Oral, Daily, Prescribed by Dr. Jones (for hyperlipidemia)

    • Acetaminophen, 500 mg, Oral, 4x Daily, Prescribed by Dr. Cain (updated 3/10/24 - dose increase for pain management)

Insurance Billing

Purpose of Prescription Insurance

  • Prescription Insurance: It aids Americans in managing increasingly rising healthcare costs by reducing out-of-pocket expenses for medications and making essential drugs more accessible.

  • Role of Pharmacy Technicians: Pharmacy technicians are tasked with efficiently and accurately processing insurance claims for patients in ambulatory pharmacies, acting as a crucial link between patients, prescribers, and insurance providers.

Formularies

Definition and Types

  • National Formulary: Maintained by the FDA, this comprehensive formulary includes all approved prescription and generic medications available on the market in the U.S.

  • Pharmacy Formulary: Managed by Pharmacy Benefit Managers (PBMs), these formularies are lists of approved medications covered by a specific insurance plan. PBMs consider factors like drug cost-effectiveness, clinical efficacy, and rebate agreements when constructing these lists. Types include:

    • Open Formularies: Generally cover a broader range of drugs, including medications not explicitly listed, often with higher premiums or cost-sharing.

    • Closed Formularies: Strictly only cover drugs that are explicitly listed on their approved list, often requiring prior authorization for non-formulary medications.

    • Restricted Formularies: Limit drugs to generics or certain medications within a specified therapeutic class, typically aiming to control costs.

    • Tiers: Divide prescription drugs into categories associated with varying patient payments or co-pays, encouraging the use of lower-cost options: usually includes generic (lowest co-pay), preferred brand drugs (mid-range co-pay), and non-preferred drugs (highest co-pay).

Drug Utilization Reviews and Evaluations

  • Purpose: To improve healthcare quality and patient safety by ensuring formulary compliance, rational drug therapy, and adherence to established clinical guidelines.

  • Authorization Process: Involves a systematic check of the drug against formulary compliance, patient eligibility, appropriate dosage and duration, and potential drug-drug or drug-allergy interactions. This process can be:

    • Prospective DUR: Occurs before the medication is dispensed (e.g., checking for interactions at the point of sale).

    • Concurrent DUR: Occurs during ongoing treatment (e.g., monitoring drug efficacy and side effects).

    • Retrospective DUR: Occurs after the medication has been dispensed to identify patterns of inappropriate use.

  • Pharmacy technicians and pharmacists are notified of any edits, rejections, or changes to prescriptions through this process and may contact prescribers regarding specific questions, issues, or to suggest therapeutic alternatives for optimal patient care.

Types of Insurance

Overview

  1. Health Maintenance Organizations (HMO): Require members to select a primary care physician (PCP), who acts as a gatekeeper and refers to specialists; typically offers the least expensive options with lower premiums and co-pays, but less flexibility in provider choice. Examples include Aetna, Cigna, Kaiser.

  2. Preferred Provider Organizations (PPO): Allow greater choice in healthcare providers, enabling patients to see specialists without referrals from a PCP; offers more flexibility but generally comes with higher premiums and potentially higher out-of-pocket costs for out-of-network care. Examples include BlueCross/BlueShield, United Healthcare.

  3. Other Programs: Include drug discount cards, Medicare, Medicaid, TRICARE, and others aimed at specific populations such as low-income individuals, seniors, or veterans.

Specific Insurance Types

  • Medicare: Federal health insurance program for those 65 or older or with certain disabilities, including several parts covering hospital, medical, and drug insurance:

    • Part A: Hospital insurance, covering inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care.

    • Part B: Medical insurance, covering certain doctors' services, outpatient care, medical supplies, and preventive services.

    • Part D: Prescription drug insurance, which helps cover the cost of prescription drugs (including recommended vaccines).

  • Medicaid: A joint federal and state program that assists low-income individuals and people with disabilities in paying for medical expenses; eligibility and coverage can vary significantly by state.

  • TRICARE: Military insurance program that covers uniformed service members, retirees, and their families worldwide with types including TRICARE Standard (fee-for-service) and TRICARE Prime (HMO-like managed care option).

  • CHAMPVA: Civilian Health and Medical Program of the Department of Veterans Affairs, providing coverage for the families of veterans with service-related injuries or disabilities, as well as surviving spouses and children of veterans who died from service-related conditions.

  • Worker’s Compensation: A form of insurance providing wage replacement and medical benefits to employees injured in the course of employment in exchange for mandatory relinquishment of the employee's right to sue their employer for negligence; typically requires no patient payment.

Troubleshooting Insurance Issues

Common Errors Leading to Rejections

  • Incorrect patient details: name, birth date, and insurance company ID or group number.

  • Situations such as “Patient not covered” (eligibility issues), “Too early to refill” (refill too soon), “Prior Authorization Required”, “Invalid Prescriber National Provider Identifier (NPI)”, or “Missing/Incorrect Diagnosis Code” can arise.

  • Pharmacy technicians must communicate errors clearly to insurance companies, gather necessary information, and often involve the prescriber or patient to resolve the issue effectively.

Understanding Insurance Billing Process

Key Terminology

  • Adjudication: The electronic process of transmitting a prescription claim to the correct insurance provider for real-time approval, rejection, or calculation of patient cost-share.

  • Claims: Formal requests for reimbursement sent by health care providers (pharmacies) to insurance companies for services or medications rendered.

  • Co-pay: A fixed dollar amount (e.g., 20$) that patients pay out of pocket for a covered prescription drug at the time of service, after which the insurance covers the remaining approved cost.

  • Deductible: The amount patients must pay annually out of pocket for covered healthcare services or medications before their insurance plan begins to pay benefits.

  • Dispense as Written (DAW): Prescribers’ instruction indicating the use of a specific brand-name drug over a generic equivalent, often due to medical necessity.

  • Co-insurance: The percentage of the cost of a covered health service you pay (e.g., 20\%$) after you’ve paid your deductible (e.g., if a drug costs 100$ and your co-insurance is 20\%$, you pay an additional $$20$ after deductible).

  • Prior Authorization (PA): A process required by some insurance plans for certain expensive or specialized medications to be covered, necessitating a review by the insurance company based on medical necessity.

  • National Provider Identifier (NPI): A unique 10-digit identification number for all covered healthcare providers, mandated by HIPAA.

  • Group Number: A specific identification number on an insurance card that identifies the health plan associated with an employer or organization.

  • Member ID: A unique identifier for the individual covered under the insurance plan, also found on the insurance card.

Information Systems in Pharmacy

Requirements

Pharmacy systems need to support various crucial operational aspects:

  • Order entry (inpatient and outpatient) for accurate prescription processing.

  • Inventory management, including tracking stock levels, ordering, and expiration dates.

  • Clinical monitoring for potential drug interactions, allergies, contraindications, and appropriate dosing to ensure patient safety.

Report Generation

Pharmacy technicians are responsible for accurate data entry to generate various reports that review financial performance (e.g., claims reconciliation, profit margins) and operational statistics (e.g., prescription volume, error rates), which are vital for pharmacy management and compliance.

Summary

Pharmacy billing necessitates comprehensive and up-to-date knowledge of billing terms, insurance policies, and claim processing procedures. This enables pharmacy technicians to assist effectively in these complex operations, ensure patient access to medications, and maintain pharmacy financial health. Proper and continuous training is vital to successfully manage intricate billing tasks and navigate evolving healthcare regulations.
