Canadian pharmacy billing guides

These guides explain the reasoning behind common claim problems at a Canadian pharmacy counter. Use a guide when the cause or next step is unclear; use the lookup tool when you already know the workflow and need a specific carrier, code, program, or form.

Start with the claim in front of you

Capture the exact response. Keep the rejection wording, response code, payer, date of service, DIN or PIN, quantity, day supply, and prescriber identifier together. A paraphrase can hide the field that actually failed.

Separate the failure layer. Decide whether the problem is identity, eligibility, product coverage, timing, authorization, price, payer order, or documentation before changing the claim.

Verify the current source. Match the claim to the relevant public-program document, provider manual, carrier resource, or direct plan instruction. A code that paid on another claim is not proof that it is truthful here.

Record the decision. Document what was verified, what changed, who was contacted, and why the final submission matched the prescription and plan rule.

Worked route: early refill after a dose change

Confirm the new directions and effective date, calculate the medication actually remaining under the old directions, and identify the resulting gap. Then check the payer's current refill rule. If an intervention is permitted, the record should support the dose change and the quantity needed; if the plan requires authorization or a call, repeated resubmission is not a substitute.
