Should You Drop Delta Dental? A Decision Framework

Delta Dental is the largest dental insurer in the US, covering over 80 million people. For many practices, it represents 20-40% of their patient base. It also has some of the lowest reimbursement rates in the industry. The question isn't whether Delta is costing you money — it is. The question is whether you can afford to drop it.

The Delta Dental Problem

Delta Dental Premier and Delta Dental PPO are different networks with different fee schedules. PPO rates are typically 15-25% lower than Premier rates, which are already below most dentists' UCR fees. On a crown (D2740):

If you do 150 crowns per year, the difference between UCR and Delta PPO is$63,000 in annual write-offs on this single procedure.

The Decision Framework

Dropping Delta is not a binary decision. Here's a structured way to think about it:

Step 1: Calculate Your Delta Write-Off

Pull your top 20 procedure codes. For each, calculate (UCR - Delta fee) × annual volume. Sum them. This is your total annual write-off to Delta specifically.

Step 2: Determine Delta Patient Percentage

What percentage of your active patients have Delta? Run a report from your practice management software.

• <15% of patients: Low risk to drop. Do it.
• 15-30%: Moderate risk. Plan carefully, prepare retention strategy.
• 30%+: High risk. Consider a phased approach or negotiate first.

Step 3: Assess Your Demand

• Hygiene booked 3+ weeks out? You have demand to absorb the loss → drop
• Empty chairs daily? You need the volume → negotiate instead
• New patient flow strong? You can replace lost patients → drop
• In a competitive market with many Delta-accepting practices? Patients can easily switch → negotiate first

Step 4: Model the Economics

Assume you retain 65% of Delta patients after dropping. The 65% now pay full UCR fee (or your membership plan rate). Calculate:

• Revenue lost: 35% of Delta patients × their annual production
• Revenue gained: 65% of Delta patients × (UCR - old Delta fee) increase
• Net impact: If gained > lost, the math works

Example: 200 Delta patients producing $400K/year at Delta rates. Drop Delta: lose 70 patients ($140K), but remaining 130 now produce at UCR — $260K × 1.30 = $338K. Net: $338K vs. old $400K = $62K loss. But you freed up 70 patient slots that can be filled with full-fee or better-paying PPO patients. If you fill even half those slots at UCR, you come out ahead.

The Alternatives Before Dropping

Negotiate First

Call Delta's Provider Relations and request a fee schedule review. Provide:

• Your patient volume on their plan
• Your retention rate (how many patients you've kept)
• Specific codes where reimbursement is below your cost
• A clear ask: "We need 15% increase on D2740, D2750, D4341, D1110"

Success rate: ~40%. Average increase when successful: 8-12%. Not transformative, but $20K-$50K/year depending on practice size.

Drop PPO, Keep Premier

You can be out-of-network for Delta PPO while staying in-network for Delta Premier. Premier rates are 15-25% higher. This is the most common intermediate step — you gain revenue without losing as many patients.

Phase Out Gradually

Instead of dropping completely:

1. Stop accepting new Delta PPO patients (existing patients continue)
2. Build your membership plan and shift existing patients over time
3. After 12-18 months, formally drop with much smaller patient exposure

Retention After Dropping

Real-world data from practices that dropped Delta:

The #1 retention tool: a well-designed in-house membership planat $25-$35/month that includes 2 cleanings, exams, x-rays, and 15-20% off treatment. This replaces the insurance relationship with a direct financial relationship.
