A useful coding audit is not a hunt for errors after the fact. It is a small, consistent sample that shows where documentation, code selection and payer rules are drifting. This is the monthly method we use to make findings actionable for providers and billers.

Choose a representative sample

Include new clinicians, high-value procedures, common diagnosis families and claims that recently denied. Explain the sample size and selection method so results can be compared month to month.

Review the note before the code

Check that the documentation supports the service, medical necessity, units and level selected. Look for missing specificity, copied-forward language and unclear medical decision-making.

Test modifiers and claim context

Review modifiers, place of service, global-period rules, bundling edits and payer-specific instructions. A technically valid code can still be wrong for the encounter context.

Separate education from correction

Correct open claims quickly, then create a short provider or staff feedback note. The goal is a safer next encounter, not a report that disappears into a shared drive.

Track the trend

Measure first-pass acceptance, coding-related denials, query volume and time to correction. Connect audit findings to the denial prevention checklist so upstream fixes are visible.

Frequently asked questions

How often should a practice audit?

Monthly or quarterly is reasonable when the sample and follow-up are consistent. Higher-risk specialties may need a tighter cadence.

Who should review the results?

Pair a qualified coding reviewer with an operational owner who can change workflows, templates or payer edits.
