What Actually Happens During a Chiropractic Billing Audit

A chiropractic billing audit is a structured review of your practice's claims and revenue cycle that finds where money is being lost — denials that were never appealed, claims that were never billed, payments below the contracted rate, and compliance gaps that quietly trigger denials. A real audit isn't a sales pitch dressed up as a report; it's a section-by-section examination measured against specific benchmarks. Here's exactly what happens during one, start to finish.

It starts with a performance snapshot

Before looking at individual claims, the audit establishes where your practice stands against four core benchmarks. These numbers frame everything that follows:

• Clean claim rate — the percentage of claims accepted on first submission without rework. Target: above 95%.
• Denial rate — the percentage of claims denied by payers. Target: below 5%.
• Days in A/R — the average time claims take to get paid. Target: under 35 days.
• Net collection rate — how much of the collectible revenue you actually collect. Target: above 96%.

If your practice doesn't know these four numbers off the top of its head, that's the first finding. You can't fix what you aren't measuring.

The eleven areas a full audit examines

From there, the audit works through each part of the revenue cycle. Each section surfaces a different kind of revenue leak:

• 1. Claim denials — every denied claim reviewed for whether it should be appealed, corrected, or written off, with the root cause identified so it stops recurring.
• 2. Claim rejections — front-end and clearinghouse rejections that never even reached the payer. These are invisible on most reports because they were never officially 'denied.'
• 3. Claims waiting to be billed — rendered services sitting unbilled in a charge-entry backlog. Care you've delivered but never submitted.
• 4. Authorizations — active, expiring, and expired authorizations, plus visit utilization, so treatment isn't rendered against an auth that's already used up.
• 5. Accounts receivable (A/R) — aging broken down by payer to find concentration risk and the claims most at risk of aging out.
• 6. Underpayments / payment variance — claims paid below the contracted rate. This is recoverable revenue almost no one checks for.
• 7. Patient responsibility / self-pay balances — copays, deductibles, and post-insurance balances, tracked separately from payer A/R.
• 8. Credentialing & payer enrollment — lapsed or pending provider enrollments, a leading cause of 'silent' denials where claims fail simply because the provider isn't active with the payer.
• 9. AT modifier & medical-necessity compliance — a spot-check of CMT claims (98940–98943) for the AT modifier, PART documentation, and medical-necessity support — the exact things that trigger Medicare audits.
• 10. Appeals tracker — the status, level, deadline, and recovered dollars of every active appeal, so nothing lapses past its filing window.
• 11. Findings & recommendations — the risk patterns, revenue-leak areas, and specific corrective actions pulled together into a plan you can act on.

Most practices are surprised by how much of the leak is invisible — not denied claims they can see, but rejections that never reached the payer, underpayments no one checks, and services that were delivered and never billed at all.

Why the AT-modifier and credentialing checks matter most

Two sections above are worth singling out because they cause losses that are almost impossible to spot from inside a busy practice. Credentialing gaps produce silent denials — the claim isn't wrong, the provider just isn't active with that payer, so it fails without an obvious reason. And AT-modifier and medical-necessity gaps are the single biggest source of Medicare audit exposure in chiropractic, because Medicare only covers active, corrective treatment and requires the AT modifier plus supporting documentation on every manipulation claim. An audit catches both before they become a pattern.

These compliance gaps are also a top denial cause — see why chiropractic claims get denied, and the coding specifics in our guide to chiropractic CPT codes.

What you walk away with

The output isn't a vague 'you could be doing better.' It's a written report showing where your four benchmark numbers actually land, which specific claims and patterns are costing you money, the root cause of each, and a prioritized list of corrective actions — high-risk areas like denials, A/R, and authorizations flagged for monthly attention, with a full audit recommended quarterly.

How to get one — free

MYRI runs this exact audit on your last 30 days of claims at no cost and no obligation. You get the written findings whether or not you ever work with us — the point is to show you what's recoverable before you decide anything. Because chiropractic is the only specialty we work in, the audit checks the things that actually matter for DC practices: region-based CPT coding, the AT modifier, PIP and personal-injury billing, and Medicare medical-necessity rules.
