How to Maximize Reimbursements: The Complete Guide for Medical Practices

Most practice owners approach reimbursement optimization the same way: see more patients, bill more claims, collect more revenue. Volume strategy. It works, to a point. But it doesn't address the percentage of revenue that's being lost on the patients you're already seeing — from undercoding, from denials, from patient balances never collected, from timely filing violations, from systematic underpayments that go undetected.

The fastest path to higher reimbursements for most practices isn't more patients. It's capturing more of the revenue that existing patients are already generating.

Here's every lever worth pulling.

Lever 1: Bill Accurately — Not Conservatively

Undercoding is a revenue leak that never generates a denial. The claim gets paid — just at a lower level than the service warranted. Because there's no denial to work, the loss is invisible. It compounds over thousands of encounters.

The 2021 AMA E/M guidelines based code selection on Medical Decision Making (MDM) or total time — replacing the previous history, exam, and MDM framework. This shift actually made higher-level codes more accessible for providers who appropriately document their clinical thinking.

A provider who sees a patient with three chronic conditions, reviews outside records, and adjusts medications has likely documented a 99215 — even if the visit felt routine. The question isn't whether the visit was complex. The question is whether the documentation reflects the MDM elements that support the code.

The first step: Conduct an E/M distribution audit. Pull the past 90 days of E/M claims per provider and compare the code distribution against national benchmarks for your specialty (CMS publishes this data annually). If your distribution skews materially lower than the benchmark, you likely have an undercoding pattern. A targeted coding audit against current MDM criteria will tell you specifically where documentation is not capturing justifiable complexity.

Lever 2: Catch Errors Before Submission With Claim Scrubbing

A clean claim rate of 95% or higher is achievable with the right pre-submission process. Below 90% means systematic errors are generating denials that require rework — and some of that rework will fail, either because the error can't be corrected or because the claim ages past timely filing.

A claim scrubber checks every claim against a rules engine before it reaches the payer:

• NCCI edits (bundling violations)
• Modifier validity against the CPT code
• Diagnosis-to-procedure medical necessity alignment
• Patient demographic completeness
• Authorization requirement flags

Waystar is the industry standard clearinghouse for mid-size and larger billing operations. Their scrubbing engine incorporates payer-specific rules beyond the standard NCCI edits, which means payer-specific modifier requirements, coverage criteria, and clinical policy requirements are checked before submission.

The ROI on claim scrubbing is straightforward: a claim caught by the scrubber and corrected before submission is paid on first pass. The same claim submitted with the error produces a denial that requires 20–30 minutes of rework — and may still not get paid.

Lever 3: Recover Underpayments from Payers

Every practice has a contract with each payer specifying the rates they'll be reimbursed for each CPT code. Payers don't always pay what the contract says. Systematic underpayment — where a payer consistently pays $88 for a code with a contracted rate of $112 — goes undetected in practices that don't compare actual reimbursements against contracted rates.

Identifying underpayments requires:

1. A current copy of each payer's fee schedule for your practice
2. A process for comparing ERA payments against expected contracted rates for each CPT code
3. A workflow for flagging and appealing underpayments when identified

This isn't a minor issue. In practices with multiple payers across dozens of CPT codes, systematic underpayment by even one payer can represent tens of thousands in annual under-collection. Finding it requires looking for it.

Lever 4: Reduce Denials by Fixing Their Root Causes

Denial recovery is important, but denial prevention is more valuable. The best billing operations track denial patterns systematically and use that data to eliminate the upstream problems that generate denials.

By payer: Which payer denies at the highest rate? What types of denials are payer-specific vs. universal?

By reason code: Eligibility denials point to front-end verification failures. Authorization denials point to authorization workflow gaps. Coding denials point to documentation or coder training issues. Each reason code category has a different upstream fix.

By provider: Some providers generate more denials than others, usually due to documentation patterns. Provider-specific denial data enables provider-specific feedback.

By CPT code: High denial rates on specific codes often indicate payer-specific coverage policies, documentation requirements, or authorization requirements that aren't being met consistently.

Monthly denial analysis that answers these questions produces specific, actionable improvements. Denial tracking that only produces an aggregate denial percentage describes the problem without solving it.

Lever 5: Collect Patient Balances at the Point of Service

Patient responsibility has grown substantially as high-deductible health plans have become the standard. The average deductible for employer-sponsored plans now exceeds $1,500. For many patients, a significant portion of their medical expenses are out-of-pocket before insurance coverage begins.

Practices that treat patient collections as a back-office function — mailing statements after the fact, making collection calls — consistently collect less than practices that make patient financial conversations part of the clinical encounter.

Collection rates at the point of service are 2–3x higher than collection rates from post-visit statements. The window is the appointment: before the patient leaves, before the bill is mailed, while the relationship with the practice is active and the visit is fresh.

What this requires:

• Real-time eligibility verification that shows deductible balance and expected patient responsibility before the appointment
• Front desk staff comfortable having a clear, professional financial conversation at check-in
• Multiple payment options: copay at check-in, card on file for patient responsibility after insurance processes, online payment portal, payment plans for larger balances
• A written financial responsibility policy signed at intake

For established patients with existing balances, asking at check-in — before the appointment — whether they'd like to take care of their outstanding balance is more effective than any amount of billing statements.

Lever 6: Verify Payer Contracts Are Up to Date

Provider contracts with payers specify reimbursement rates, coverage policies, and billing requirements. Contracts are renegotiated periodically — but the rates a practice was signed at when they first joined a network may not reflect current market rates.

Practices that have been in-network with the same payers for five or more years without a contract review are often being reimbursed at rates that have fallen behind market. A contract renegotiation supported by current market data and the practice's volume and performance metrics can produce meaningful rate improvements.

Similarly, practices that have added providers, new service lines, or new locations since their original contract was signed may have billing configurations that don't match their current operations — leading to reimbursement complications that could be resolved by updating the contract terms.

Lever 7: Don't Write Off Timely Filing Violations

A timely filing denial is permanent. Unlike most other denials, there is no appeal that recovers a claim submitted after the payer's filing deadline. The revenue is gone.

The most effective approach to timely filing is prevention: no claim should sit unsubmitted for more than 3–5 business days from the date of service, and your AR aging report should be reviewed weekly to catch claims approaching their filing windows before they cross the deadline.

But for practices that have already accumulated timely filing denials: audit your process to identify when and why claims are aging. Common causes include coding holds, authorization questions, eligibility issues that were put on hold and forgotten, and staff transitions that left claims in limbo. Fix the underlying process so the same aging pattern doesn't recur.
