How to Detect Medication Overcharging in Workers Compensation Claims?

How Do You Detect Medication Overcharging in Workers Compensation Claims?

Medication overcharging detection requires systematic comparison of invoice charges against objective pricing benchmarks and verification of compliance with jurisdiction-specific billing rules.

Note on Pricing Data: Medication prices, dispensing fees, and jurisdiction-specific limits vary frequently and by location. PBS Schedule pricing is updated monthly. State dispensing fee caps change periodically. Always verify current pricing benchmarks and jurisdiction rules when evaluating medication invoices. Savings figures and overcharging prevalence vary significantly by claim type, jurisdiction, and pharmacy practices.

Five-Step Detection Process:

Step 1: Compare Against PBS Schedule Benchmark

The Pharmaceutical Benefits Scheme (PBS) Schedule published monthly by the Department of Health provides authoritative pricing benchmarks for over 2,000 medications. Even for private prescriptions not processed through PBS, the PBS Schedule price represents reasonable market value.

• Obtain current month PBS Schedule from pbs.gov.au
• Locate medication by brand name or active ingredient
• Compare invoice price to PBS "Dispensed Price for Maximum Quantity" (DPMQ)
• Flag if invoice exceeds PBS price by >20% (allowing reasonable private prescription markup)

Step 2: Verify Dispensing Fee Compliance

Each Australian jurisdiction sets maximum dispensing fees for workers compensation medication claims:

• NSW (SIRA): $7.50 per prescription dispensed
• Victoria (WorkSafe): $8.30 per prescription dispensed
• Queensland (WorkCover): $9.50 per prescription dispensed
• Western Australia (WorkCover WA): $7.95 per prescription dispensed
• South Australia (ReturnToWorkSA): $8.00 per prescription dispensed

Any dispensing fee exceeding jurisdiction limit is recoverable overcharge.

Step 3: Check for Brand Premium Markup

When generic equivalent is available, brand-name prescribing creates unnecessary cost. Common examples of brand premium overcharging:

Step 4: Identify Inappropriate Substitution

Therapeutic substitution without prescriber authorization represents potential overcharging if higher-cost alternative dispensed:

• Original prescription: Ibuprofen 400mg ($3.50)
• Pharmacy dispenses: Nurofen Zavance 400mg ($12.95)
• Overcharge: $9.45 (270% markup) without documented prescriber request

Step 5: Validate Quantity and Pack Size

Check dispensed quantity matches prescription and represents appropriate pack size:

• Prescription: Paracetamol 1g QID, 5-day supply = 20 tablets
• Invoice shows: 100 tablet pack dispensed ($15.50)
• Appropriate: 20-30 tablet pack ($3.50-$5.20)
• Overcharge: $10.30-$12.00 for unnecessary quantity

What is the PBS Schedule and How Is It Used to Detect Overcharging?

The Pharmaceutical Benefits Scheme (PBS) Schedule is the Australian Government's authoritative medication pricing reference, updated monthly to reflect current market prices for over 2,000 subsidized medications.

PBS Schedule Components:

• Dispensed Price for Maximum Quantity (DPMQ): Total price including manufacturer price, wholesale markup, pharmacy markup, and approved pack size
• Maximum Quantity: Largest supply that can be dispensed on single prescription
• Number of Repeats: How many times prescription can be refilled
• Therapeutic Group: Clinical category and alternative medications
• Authority Required: Whether prescription requires PBS approval for subsidy

Using PBS for Workers Compensation Pricing:

Although workers compensation medications are private prescriptions (not PBS-subsidized), the PBS Schedule provides objective benchmark for reasonable pricing because:

• PBS prices are negotiated by Australian Government with pharmaceutical manufacturers representing bulk purchasing power
• PBS prices include all legitimate cost components (manufacturing, distribution, pharmacy dispensing)
• PBS prices are publicly accessible and transparent
• PBS prices are updated monthly to reflect current market conditions
• Private prescription pricing above PBS price must be justified by special circumstances (urgent supply, rural premium, specialty compounding)

Acceptable Markup Above PBS Price:

Reasonable private prescription markup varies by jurisdiction and circumstance:

• Standard markup: PBS price + 10-15% (accounts for private prescription processing and inventory)
• After-hours supply: PBS price + 25% maximum (documented after-hours dispensing only)
• Rural/remote pharmacy: PBS price + 20-30% (remote locations with limited competition)
• Specialty compounding: PBS price not applicable; verify compounding necessary

Any pricing exceeding PBS + 20% without documented justification should trigger pharmacy contact and invoice review.

How to Access Current PBS Schedule:

1. Visit pbs.gov.au/pbs/home
2. Use PBS Medicine Search tool
3. Enter medication name (brand or generic)
4. Review "Pricing" section for DPMQ
5. Download PBS Monthly Schedule PDF for comprehensive reference

What Are Common Medication Overcharging Tactics Used by Pharmacies?

Understanding common overcharging tactics enables claims managers to implement targeted detection strategies.

Tactic 1: Brand Premium Markup

Method: Dispensing expensive brand-name medication when bioequivalent generic available at fraction of cost.

Example:

• Prescription: "Ibuprofen 400mg" (generic prescribed)
• Dispensed: Nurofen 400mg (brand name)
• Generic cost: $3.50 for 24 tablets
• Brand cost: $9.50 for 24 tablets
• Overcharge: $6.00 (171% markup)

Detection: Check if generic equivalent exists; query why brand dispensed.

Prevention: Require generic substitution unless prescriber specifies "no substitution" or documented medical justification for brand.

Tactic 2: Excessive Dispensing Fees

Method: Charging dispensing fees above jurisdiction-mandated limits.

Example:

• Jurisdiction: NSW (SIRA) - $7.50 maximum dispensing fee
• Invoice shows: $18.00 "professional dispensing service fee"
• Overcharge: $10.50 (140% above limit)

Detection: Verify dispensing fee line item against jurisdiction fee schedule.

Prevention: Include jurisdiction fee limits in pharmacy provider agreements; automatic flagging of excessive fees.

Tactic 3: Compounding Charges for Standard Medications

Method: Charging compounding fees ($45-$85) for simple combinations or preparations available pre-manufactured.

Example:

• Prescription: Paracetamol 500mg + Codeine 30mg (Panadeine Forte - pre-made tablet)
• Invoice shows: $67.50 "compounding fee" + $12.00 ingredients
• Actual product: Panadeine Forte pre-manufactured tablets ($15.40 PBS price)
• Overcharge: $64.10 (416% markup)

Detection: Verify medication is truly compounded; check if pre-manufactured equivalent exists.

Prevention: Require prescriber confirmation that compounding necessary; request formula and justification.

Tactic 4: Quantity Rounding and Oversupply

Method: Dispensing larger pack size than prescription requires, billing for full pack.

Example:

• Prescription: Endone 5mg, 1-2 tablets QID PRN, 3-day supply = 6-24 tablets
• Appropriate dispense: 20-30 tablet pack ($28.60 PBS price)
• Actual dispense: 100 tablet pack ($87.50)
• Overcharge: $58.90 (206% markup) for 70-80 unnecessary tablets

Detection: Calculate expected quantity from prescription directions; compare to invoice quantity.

Prevention: Flag any Schedule 8 opioid quantity exceeding 30 tablets or 7-day supply.

Tactic 5: Inappropriate Therapeutic Substitution

Method: Substituting higher-cost therapeutic alternative without prescriber authorization.

Example:

• Prescribed: Diclofenac 50mg tablets ($7.85 for 50 tablets)
• Dispensed: Meloxicam 15mg tablets ($24.50 for 30 tablets) - different NSAID
• Justification: "Similar therapeutic effect"
• Overcharge: $16.65 + requires prescriber authorization for different medication

Detection: Verify dispensed medication matches prescribed medication; query any substitution.

Prevention: Require prescriber approval for any therapeutic substitution before dispensing.

Tactic 6: Double-Billing and Unbundling

Method: Separating bundled services to bill multiple times.

Example:

• Medication cost: $15.00
• Dispensing fee: $8.50
• Additional charges: "Consultation fee" $25.00, "Medication review" $35.00
• Total: $83.50
• Appropriate: $23.50 (medication + dispensing only)
• Overcharge: $60.00 (255% markup) for unbundled services

Detection: Identify charges beyond medication + dispensing fee; query justification.

Prevention: Clarify in provider agreement that dispensing fee covers all standard services.

Tactic 7: Slow Generic Adoption

Method: Continuing to dispense brand-name medication months after generic becomes available.

Example:

• Lyrica (pregabalin brand) lost exclusivity September 2023
• Generic pregabalin: $28.50 for 56 x 150mg capsules
• Pharmacy continues dispensing Lyrica brand: $97.40
• Overcharge: $68.90 (242% markup) per prescription

Detection: Monitor PBS F2 (formulary) section for recently genericized medications; verify generic dispensing.

Prevention: Implement automatic generic substitution policy; flag continued brand dispensing post-generic availability.

What Are Red Flags for Medication Overcharging?

These patterns on medication invoices warrant immediate investigation:

Pricing Red Flags:

• Brand names for commodity medications: Panadol, Nurofen, Voltaren when generics available
• Prices 50%+ above PBS benchmark: Without documented justification
• Dispensing fees >$10: Exceeds all jurisdiction limits
• Compounding charges >$50: Verify compounding truly necessary
• Inconsistent pricing: Same medication costs different amounts on different dates
• "Professional service" fees: Unbundled charges beyond dispensing fee
• Private prescription pricing: For medications available on PBS

Prescribing Pattern Red Flags:

• Multiple prescriptions same date: Each with separate dispensing fee (should be combined)
• Frequent early refills: Suggests quantity oversupply on each fill
• 90-day supplies for acute injuries: Expected to resolve in 2-3 weeks
• No generic substitution: All medications dispensed as brands despite generic availability
• Unusual pack sizes: Creating medication waste
• "No substitution" markings: On all prescriptions without medical justification

Pharmacy Behavior Red Flags:

• Resistance to generic substitution: When questioned about brand dispensing
• Incomplete invoices: Missing quantity, PBS code, or medication strength
• Delayed invoice submission: Submitted months after dispensing
• Altered prescriptions: Quantity or directions modified without prescriber contact
• Refusal to provide PBS pricing: When requested by claims manager
• Same-day dispensing across multiple pharmacies: Indicates potential fraud or duplication
