Dental Insurance Audit Preparation in Canada: A Practical Guide

Why audit preparation deserves a process

Insurance carriers and benefit administrators periodically review dental claims to confirm that billed procedures are supported by the patient record. For most offices, an audit request arrives with little warning, a defined response window and a list of patients, dates of service and procedure codes to substantiate.

Without a repeatable process, the response often falls to whoever is available: an office manager pulling charts between patients, a billing coordinator printing radiographs, a dentist reviewing notes after hours. A defined workflow reduces stress and makes the submission easier for the reviewer to follow.

Step 1: Read the request carefully

Before gathering anything, record exactly what was requested. Note the response deadline, the patients and dates of service in scope, the procedure codes listed and the format the carrier prefers. Ask the carrier for clarification in writing if the scope is unclear.

• Log the date the request was received and the deadline.
• Create a single list of every claim line in scope.
• Identify who in the office owns the response and who the reviewing dentist will be.

Step 2: Gather records from their original sources

For each claim line, collect the relevant clinical notes, radiographs, intraoral images, periodontal charting, treatment plans, consent forms, lab prescriptions and the claim as submitted. Export copies from your practice management and imaging systems rather than recreating documents.

Original records should remain unchanged. If a correction or late entry was made in the chart, it should already be dated and attributed according to your regulatory college's record-keeping guidance — never backdated for an audit.

Step 3: Cross-check billing against documentation

Review each billed code against the supporting chart entry. Common questions include whether the tooth and surfaces match, whether the documented findings support the procedure, whether the date of service aligns and whether required images are present.

Step 4: Dentist review and approval

The treating or responsible dentist should review the assembled package before it leaves the office. Clinical judgement about what the record shows belongs to the dentist, not to administrative staff or software.

Step 5: Assemble an organized submission

Organize the package by patient and date of service, include an index, and keep a copy of exactly what was sent along with the date and method of submission. A clear structure helps the reviewer and creates a record for your office.

Preparation does not guarantee any particular audit outcome. Its purpose is to present accurate, complete records clearly and on time.
