Outpatient Claims Audit
Office visits, procedures, diagnostics, and imaging reviewed across the outpatient claim mix.
Outpatient claims are individually small and collectively enormous, which is exactly the shape that hides error. A one-level E/M discrepancy is trivial on a single claim and material across twenty thousand of them.
ZechionMed's outpatient claims audit reviews the mix an outpatient organization actually bills: office visits, in-office procedures, diagnostic services, and imaging — each against its own documentation and payer rules.
The audit is built around volume. Findings are reported as rates and patterns rather than lists of individual claims, because at outpatient volume the pattern is the finding.
What We Cover
What We Review
Office Visit Audit (E/M)
The highest-volume claim type in outpatient care and the most audited coding decision in medicine.
- E/M level support in documentation
- Medical decision making assessment
- Time-based coding verification
- New versus established patient determination
- Preventive versus problem-oriented visit review
- Level distribution against peers
- Modifier 25 where a procedure was also performed
Procedure Claims Audit
In-office procedures, which are routinely under-captured and occasionally over-modified.
- CPT procedure code validation
- Procedure documentation review
- Product and supply billing
- Bundling and NCCI compliance
- Global period application
- Same-day E/M and procedure billing
- Missed procedure charge identification
Diagnostic Services Audit
Diagnostic testing, where medical necessity and diagnosis linkage carry the denials.
- Diagnostic procedure code review
- Diagnosis-to-service linkage validation
- Medical necessity documentation
- Coverage determination compliance
- Frequency limitation compliance
- Ordering provider documentation
Imaging Claims Audit
Imaging carries the component-split question and the heaviest authorization requirements.
- Professional and technical component accuracy
- Global billing appropriateness
- Contrast study coding
- Multi-region study coding
- Authorization verification
- Radiopharmaceutical billing where applicable
Claim Data Accuracy
The mechanical elements that reject a claim before anyone assesses the clinical content.
- Place-of-service accuracy
- Units and quantities
- Provider and NPI accuracy
- Referring and ordering provider data
- Date-of-service consistency
- Payer and plan accuracy
What We Cover
How Findings Are Reported
Rates and Patterns
At outpatient volume a list of individual errors is unusable; a rate is actionable.
- Error rate by claim type
- E/M level distribution by provider
- Denial correlation with findings
- Payer-specific error concentration
- Trend across the review period
Financial Impact
Both directions, because outpatient audits usually find revenue as well as risk.
- Under-coded revenue identified
- Missed procedure and supply charges
- Over-coding exposure quantified
- Still-correctable claims flagged
- Net financial impact by category

Why Outpatient Volume Hides Error
Individually trivial, collectively large
A one-level E/M discrepancy is worth very little on one claim. Across a year of outpatient volume it is one of the largest single findings an audit produces.
In-office procedures get missed
A procedure performed during a visit is separately billable with the right documentation. Capturing only the E/M is a high-frequency, low-visibility loss.
Defensive coding is widespread
Fear of audit produces systematic down-coding, which no compliance process looks for because it creates no risk.
Diagnostic necessity is assumed
Diagnostic testing is denied on medical necessity and frequency limits more than on coding, and the documentation to support it is often absent.
Nobody audits the mechanical fields
Place of service, units, and ordering provider data reject claims before the clinical content is even assessed, and they are rarely reviewed.
