Which Insurance Payers Are Draining Your Practice's Profitability?

Most dental practices track total revenue. Few track revenue by payer. Those are two very different numbers.

Your top payer by volume is not always your top payer by margin. Industry data consistently shows double-digit spread between best and worst payer reimbursement on the same procedure. To put numbers to it: a crown that nets $650 under one contract and $410 under another is not unusual. Multiply a gap like that across 800 crowns a year and you are looking at a six-figure difference in net collections.

What Payer Analysis Actually Shows

When you break down collections and write-offs by insurance carrier, four things become clear fast:

Most contract fee schedules auto-renew. Payers count on that. A two-year-old Delta contract at 2023 fee levels costs you money on every procedure. The practice does not notice because write-offs get normalized into the monthly numbers.

What the Numbers Look Like

Consider a five-provider practice with $2.4M in annual production. Three carriers with an effective collection rate below 58% would look fine against an overall rate of 67%. The problem is buried in the average. If those three carriers represent 30% of patient volume, they drag the overall number down significantly — and the practice never sees it without breaking the data out by payer.

The Denial Rate Problem

Claim denials have a direct cost most practices undercount. Each denied claim requires 15 to 30 minutes of staff time to review, correct, and resubmit. At $25 per hour, a 10% denial rate on 500 monthly claims adds $1,875 to $3,750 in labor costs. Some payers deny three times more claims than others. That is not random. It is a contract and process problem you can measure.

Track denial rates by carrier. If one payer denies 18% of claims and your average is 6%, that carrier is consuming staff time well beyond what their reimbursement rate suggests.

Three Decisions the Data Makes Easier

Renegotiate with data behind you. Most carriers will negotiate, especially if you bring volume data showing your patient mix and procedure distribution. Walking in with a breakdown of your fee schedule vs. actual reimbursement by procedure code changes the conversation entirely.

Adjust your scheduling mix. If Medicaid patients represent 40% of your schedule and 12% of your net margin, that is a strategic choice. The data does not make the decision for you. It makes the decision clear so you can make it intentionally.

Drop the worst contracts. This is the hardest call. Some payers deliver enough volume that lower margins still make sense. Others do not. You cannot make that call without the numbers.

The Renegotiation Opportunity

Delta Dental, Cigna, and Aetna all have renegotiation processes. Practices that request reviews with supporting production data get better outcomes than those that accept auto-renewals. The data gives you standing in the conversation.

Start With 12 Months of Claims Data

Pull 12 months of collections by payer from your practice management system. Calculate net collections after adjustments for each carrier and compare against submitted charges. That gap is your effective discount rate per payer.

Most practices find two or three payers where that number surprises them. Those are your starting points.

If your practice management system does not surface this view cleanly, that is a reporting gap. The data exists. It just needs to be structured correctly to be readable.
