Key points
- Authorization and reimbursement are separate decisions.
- Different DINs for the same ingredient may receive different answers.
- Plan criteria and formularies can change.
The four coverage layers
First identify the exact product and DIN. Then identify the payer: provincial or territorial program, employer or individual private plan, or both. Next check listing and clinical criteria. Finally confirm deductible, copay, coordination and authorization steps.[1][2][5]
Public drug plans are provincial and territorial
Canada’s publicly funded systems are administered by provinces and territories. Ontario and British Columbia, for example, provide official medication or formulary search tools, but their results and rules are not interchangeable with another jurisdiction.[1][3][4]
Questions for a private plan
Give the plan the exact DIN and ask whether the product is listed for the prescribed indication, whether prior authorization or step criteria apply, what documentation is required, and what the patient share would be. Ask how coordination with a public plan works if both may apply.[2]
A denied claim needs a reason
Ask whether the denial reflects an excluded product, unmet criteria, missing authorization, deductible, quantity rule or data-entry issue. Then discuss clinical alternatives with the prescriber and price alternatives with the pharmacist. Use the cash-cost method before assuming a denied claim makes access impossible.
A claim outcome does not determine whether a medication is clinically suitable.
