Audit

An audit in the dental billing context is a formal examination of a practice's submitted claims, supporting clinical documentation, and coding patterns. Audits can be conducted internally by the practice itself, externally by insurance carriers, or by government agencies such as state dental boards or federal programs like Medicaid. The primary purpose is to ensure that the procedures billed match the services actually performed, that CDT codes are applied correctly, and that clinical documentation supports the medical necessity of the treatment rendered.

Internal audits are a proactive compliance strategy that every dental practice should incorporate into its revenue cycle operations. A well-structured internal audit program involves pulling a random sample of claims on a regular basis, typically monthly or quarterly, and reviewing them against the clinical record. Auditors check whether the CDT code matches the procedure note, whether radiographs and charting support the diagnosis, whether the provider's documentation meets the payer's requirements for medical necessity, and whether fees were charged correctly. Identifying and correcting patterns before a payer discovers them protects the practice from recoupment demands, which can involve paying back months or even years of overpayments.

External audits initiated by insurance carriers or government agencies can be triggered by statistical outliers in a practice's claims data. For instance, if a practice's use rate for a particular procedure is significantly higher than the regional average, the carrier may flag the practice for review. Preparing for these audits requires maintaining thorough, contemporaneous clinical records that clearly justify every billed procedure. Practices that invest in regular internal audits and staff training on proper coding and documentation are far better positioned to withstand external scrutiny and avoid the financial and reputational damage that can result from adverse audit findings.
