Clinical Documentation Audits: Medical Necessity, QA and Compliance
Medical necessity documentation is the proof behind every claim: if the record doesn't show why a service was needed, the payer can take the payment back. Missing or insufficient documentation accounted for 65% of Medicare's fee-for-service improper payments in fiscal year 2025. Our quality assurance program reviews your progress notes weekly, trains your staff monthly and monitors documentation deadlines.
The short answer
What should medical necessity documentation include?
Proof that each service was provided, at the level billed, and medically necessary. Florida Medicaid's Rule 59G-1.054 lists what each visit record must show, from the chief complaint and diagnosis to progress reports and the treatment plan; insufficient documentation accounted for 53.0% of Medicare's fee-for-service improper payments in fiscal year 2025. The Advixor Group's quality assurance program reviews your progress notes weekly, trains your staff monthly and monitors documentation deadlines.
Two Tests
Medical necessity documentation: the test each payer applies
Medicare pays only for “reasonable and necessary” services (42 U.S.C. 1395y(a)(1)(A)). Florida Medicaid’s definition has five parts, all required:
- It is necessary to protect life, prevent significant illness or disability, or relieve severe pain (for patients 21 and older).
- It is individualized, consistent with the symptoms or diagnosis, and no more than the patient needs.
- It meets accepted professional standards and isn’t experimental.
- It is the level of care that can be given safely, and no equally effective treatment that is more conservative or less costly is available statewide.
- It isn’t mainly for the convenience of the patient, the caretaker or the provider.
“The fact that a provider has prescribed, recommended, or approved medical or allied care, goods, or services does not, in itself, make such care, goods or services medically necessary or a medical necessity or a covered service.”
What Auditors Check
Chart audit checklist: Medicare and Florida Medicaid side by side
A clinical documentation integrity review checks the same items an auditor does.
| What the auditor checks | Medicare (fee-for-service) | Florida Medicaid |
|---|---|---|
| Signature | The treating practitioner’s | Signed and dated, or authenticated by initials or computer entry |
| Deadline to sign | No set deadline; an attestation may resolve a missing signature, except on a required order or when a rule set a date | Two business days from the date and time of service |
| Rubber stamp | Not typically accepted; allowed for an author with a documented physical disability | Must be initialed |
| Illegible signature | Signature log or attestation, within 20 calendar days of the request (not for CERT) | Records must be legible |
| Late entry | Dated, authored and “clearly and permanently denoted” | May be considered only if germane, made before notice of the audit and added to a contemporaneous note |
| Records kept | 7 years for orders, certifications, referrals and prescriptions | 5 years from the date of service (6 for crossover-only providers) |
Sources CMS Program Integrity Manual ch. 3, MLN905364, MLN909160, 42 CFR 424.516(f), Rule 59G-1.054, s. 409.913(21)–(22).
Florida Medicaid
Documentation required for Medicaid in Florida, visit by visit
Unless a coverage policy says otherwise, Rule 59G-1.054 requires each visit record, whatever its format (SOAP or another), to show the chief complaint, the date of service, the services rendered, the diagnosis, tests and results, the history and physical, medications and supplies, progress reports, referrals, follow-up scheduling and the treatment plan (several only as applicable).
You send agencies legible copies of requested records at your own expense.
Behavioral Health
Clinical documentation in behavioral health: treatment plans and therapy notes
For therapy and behavioral health practices, Florida Medicaid’s coverage policies add these checks:
- The treatment plan sets the amount, frequency and duration of each service for six months, never “as needed” or a date range, with the treating practitioner’s statement that the services are medically necessary.
- The plan takes effect on the practitioner’s signature, and Medicaid “reimburses for services provided within 45 days of the signature.”
- The plan is reviewed every six months or after a significant change; without one, an addendum signed by the practitioner and the recipient can add or modify services.
- Therapy: a daily progress note for each service and proof the service is on the plan. Groups run 2 to 15 participants, and every therapy provider must be employed by or contracted with a community behavioral health agency.
Medicare reviewers may never request psychotherapy notes as HIPAA defines them, but session times, modalities, diagnosis, the treatment plan and progress aren’t psychotherapy notes, even in the same document; if what you send doesn’t show medical necessity, the claim is denied.
Medicare Audits
Medical record audit by Medicare: CERT and Targeted Probe and Educate
CERT reviews a random sample of fee-for-service claims each year. For fiscal year 2025 it found 6.55% of payments improper, $28.83 billion, and 8.44% for Part B providers. Among Part B provider types, psychiatry ran 13.3% (60 claims), nurse practitioners 7.2% (835 claims).
“Insufficient” means the reviewer couldn’t tell whether a service was provided, at the level billed, or medically necessary (MLN909160).
Your MAC runs Targeted Probe and Educate (TPE) for providers with high error rates or unusual billing: generally 20 to 40 claims a round, with education after each. Problems that persist after 3 rounds go to CMS, which may order 100% prepayment review, extrapolation or a Recovery Auditor referral. Low billers get rounds of fewer than 20 claims, up to three.

After a Finding
Compliance documentation after a finding: extrapolation, refunds and self-audits
- 60 daysto report and return a Medicare overpayment you identify.
- 180 daysthe longest a timely, good-faith investigation can suspend that deadline.
- 6 yearsthe lookback period.

AHCA’s self-audit guidance asks for claim-by-claim detail, and repaying on its terms is the condition for amnesty from sanctions, though further review or enforcement stays possible. Ask your attorney whether and how to disclose.
AHCA’s Medicaid Program Integrity office validated 333 self-disclosures worth $385,579 in FY 2024–25. On June 12, 2026, the state announced more claims monitoring and a revalidation of every active Florida Medicaid provider.
We also prepare Medicaid self-audits and Medicare refunds, working alongside your attorney.
Our Program
Quality assurance in healthcare: our weekly and monthly program
Our Clinical Documentation and Quality Assurance Program is part of our healthcare consulting for medical and behavioral health practices.
Each audit samples your records and claims, checks them against the payer’s rules, reports the patterns, trains your clinicians and re-audits.
The sample size, the look-back period and the payer rules are set for your practice before the first audit, and the fee and turnaround are quoted in writing after we go over your needs.
Quality assurance program
The program includes:
- Weekly review of progress notes
- Monthly training by employee classification and identified needs (HR and staff training)
- Monthly supervision meetings with the clinical director
- Monitoring of caseloads and documentation deadlines
- Weekly curriculum review and maintenance, where it applies
