Medical Record Review and Data Validation
Medical Record Review and Data Validation tests whether you can verify that the record is complete, authentic, contemporaneous, and internally consistent with the claim and other data sources.
Core rules
- Confirm patient identity, date of service, provider identity and credentials, setting, and authentication. An unsigned or undated note is generally not acceptable unless the EHR supplies a valid electronic signature and audit trail.
- Late entries and amendments must be dated, timed, and attributed; the original content should remain visible. Deletions without an audit trail are a red flag.
- Review the whole record: history, exam, results, orders, medication administration, operative/procedure note, discharge instructions, and prior authorizations. A single progress note may not tell the story.
- Validate claim fields against the record and system data: CPT/HCPCS, modifiers, units, diagnosis linkage, place of service, NPI, and date. Units need a documented amount administered, wasted, or discarded, as applicable.
- Use EHR audit logs for copy/paste, late edits, and access anomalies, but interpret them cautiously.
Worked example
A claim reports J3301 (triamcinolone acetonide, 10 mg) at 4 units. The procedure note documents 20 mg injected and no wastage. Four units would represent 40 mg. The supported units are 2; the additional 2 units are an overbilling finding unless another documented dose or waste supports them. The auditor records the exact note language, the code descriptor, and the calculation.
Traps
- Accepting a patient recall or billing summary as clinical documentation.
- Treating a late addendum as if it were part of the original note without attribution.
- Ignoring copy/paste that creates contradictory histories.
- Failing to check place of service, which can change payment.
- Validating only the CPT code and not the diagnosis, units, or modifier.
