Pharmacy Accounting BasicsMargin = Amount paid by patient–acquisition

cost of drugsNet Profit = Total revenue – total expenses Total revenue must exceed total expensesSignificant changes in reimbursement for drugs

affects pharmacy profitsPharmacy technicians

knowledge of reimbursement is significant role

Reimbursement BasicsBased on many factors including:

practice setting type of drug who is paying for drugs

Prospective paymentall costs associated with treating conditiondeliver drugs at or below predetermined rate

Retrospective, or fee for servicedrugs are dispensed & later reimbursedpredetermined formula in contract between

pharmacy & 3rd party payer (insurance company or PBM)

3rd Party Contract FormulaIngredient cost

benchmark (several options in later slide)Dispensing fee

covers costs of dispensing prescriptionCopayment aka “copay”

cost-sharing amount paid by patient or customerPharmacy profitReimbursement > costs to dispense

prescriptionreimbursement= (ingredient cost + dispensing fee) –

copayment

Cost TermsAverage wholesale price (AWP)

commonly used benchmark created in 1960savailable from MediSpan & First Databank

Known as “sticker price” AWP usually set at 20–25% above wholesale

acquisition cost (WAC)

Cost TermsWholesale acquisition cost (WAC)

set by each manufacturer“list price” manufacturer sells to wholesaler

Does not include discounts or price concessionsIf AWP is basis for reimbursement, formula is

usually AWP less some percentageIf WAC is basis, formula is usually WAC plus

small percentageNeither AWP nor WAC represent actual cost of

drugs

Cost TermsNew benchmarks Average sales price (ASP)

based on manufacturer-reported selling price data

includes volume discounts & price concessionsAverage manufacturer price (AMP)

average price paid to manufacturers by wholesalers

includes discounts & other price concessions

DRABudget Deficit Reduction Act of 2005 (DRA)

requires AMP to calculate federal upper limit for drugs paid through Medicaid

FUL=funds from feds to state Medicaid programs Patient Protection & Affordable Care Act of

2010 AMP was established as 175% of ASPReimbursement formula for generic product

different than for brand productBrands reimbursed based on AWP or WAC

MACMaximum allowable cost

based on cost of lowest available generic equivalent

Payment2008 Stats:

private insurance paid for 42% Medicare and Medicaid paid for 37%consumers paid 21%

PAPsPatient assistance programs (PAPs)

low-income patients who lack prescription drug coverage and meet certain criteria

Criteria for PAPs are widely variabledetermined by individual drug companiesmostly proprietary drugs in PAPs patient is required to complete application

Drug company sends drug to licensed pharmacist or physician on patient’s behalf

IPAPsInstitutional patient assistance programsMedications are provided to institutionInstitution verifies patient meets established

criteriaPharmacies receive “replacement” product Pharmacy technicians play important role

PBMsPharmacy Benefit Managers

administer pharmacy benefits for private or public 3rd party payers

aka plan sponsorsMajor PBMs

CVS CaremarkMedcoExpress ScriptsWalgreens Health InitiativesWellpoint Pharmacy Management

PBMsSponsor pays PBM fee

Fee covers total cost of pharmacy benefitPBM administers pharmacy benefit under

direction of sponsorPBM manages benefit so cost of prescriptions

does not exceed amount of money paid to PBM by sponsor

Formulary cornerstone of PBM activitiesPreferred & nonpreferred

may charge different copays or copay tiers

PBMsPrior authorization

requires prescriber to receive preapproval from PBM

used for newer drugsStep therapy

must try & fail on recognized first-line drug before expensive second-line drug is covered

PBMsQuantity limits

HCPCS CodesHCPCS federal coding system consists of 3

levels:Level I-Current Procedural Terminology codes

(CPT)Level II-National Alpha-Numeric codes (CMS)

standardized coding system used to identify products, supplies, services not

included in CPT codesLevel III-Local Alpha-Numeric codes
