Pre-Built Scenarios — Most Common Stacking Situations
Scenario 01
The MetLife Drag
You hold direct contracts with Aetna, Ameritas, and Guardian. MetLife PDP now leases to all three (2025). When any of their patients visits, MetLife's below-average fee schedule applies — not your direct contract rate. Estimated annual drag: $18,000–$52,000 for a mid-volume practice.

Revenue lost on this claim: $200 (−20%)
Aetna's fee schedule paid $1,020 for this crown. MetLife PDP pays $820. You absorb the $200 gap — invisibly.

Opt-out: Use the opt-out form at dentalprovider.metlife.com/networkswap to remove Aetna from the MetLife PDP lessee access. Same form covers all MetLife lessees — you can opt out of specific carrier arrangements.

Pathway Selection Probability
When a carrier has multiple pathways to your practice, they almost always select the lowest fee schedule. Probability is weighted by estimated fee schedule differential — the larger the gap, the higher the probability of selection.

Scenario 02
The CDN Advantage
You're contracted with GEHA Connection Dental (CDN). Cigna joined CDN in August 2023. Ameritas joined in July 2023. Aetna MA now routes exclusively through CDN or direct PPO (eff. Sept 2025). CDN's federal FEHB fee schedule reimburses at or above commercial carrier rates — meaning patients from Cigna, Ameritas, and Aetna MA are processed at higher federal rates instead of those carriers' own (often lower) commercial schedules. CDN is a provider-favorable network.

D2750 crown: ~$980–$1,080 (est. federal rate)

Ameritas would pay ~$960 (mid-range) — CDN pays ~$1,020 +$60
Aetna MA would pay ~$850 (MA rate) — CDN pays ~$1,000 +$150
One CDN contract, three above-market revenue pathways. CDN's federal FEHB schedule is a genuine provider advantage — especially for Cigna patients, where the uplift vs. Cigna's new ~40% write-off schedule is significant.
Routing Probability by Carrier
Unlike the MetLife scenario, these carriers don't have a "choice" of pathways — they access you only through CDN. Probability = 100% for all three. The question is what percentage of each carrier's patient population routes through CDN vs. direct contract.

The strategy: Prioritize and protect your CDN contract. If you're contracted with Cigna directly AND through CDN, ensure CDN is positioned as your primary network for Cigna patients — the reimbursement uplift is substantial given Cigna's new ~40% write-off schedule. For Aetna MA specifically, CDN is now the primary non-direct pathway after Aetna terminated all other lease arrangements (eff. Sept 2025).

Scenario 03
The UC Quad Stack
You're contracted with Ameritas, DenteMax, Humana, and Principal — all mid-range carriers. United Concordia can access you through all four simultaneously. UC picks whichever pathway gives the lowest reimbursement. This is the exact scenario documented in Dental Economics. The Companion Life CO state filing demonstrates this with a 2-pathway stack (UC → DenteMax fallback), confirmed in writing.

Revenue lost this claim: ~$50 (−5%). All pathways are mid-range — the stack exists but the fee differential is smaller. Still adds up: at 200 UC claims/year × $50 avg gap = $10,000 annual leak that's invisible without an EOB audit. Source: Dental Economics, Companion Life CO state filing.
Why Lower Probability = Lower Differential
When all pathways are mid-range, the fee differential between pathways is small (3–6%). The carrier still picks the cheapest, but the selection probabilities compress — a 38/25/22/15 split rather than an 85/15 split. The leak is real but smaller.

Scenario 04
The DHA Web
You're contracted with Dental Health Alliance (Sun Life). Per the July 2025 DHA payor list, 8+ carrier groups access you via DHA — including MetLife (below-average) and Cigna (below-average). The new MetLife→DHA arrangement (eff. 10/18/2025) is the riskiest addition: MetLife's confirmed low fee schedule now applies to all MetLife patients at DHA-contracted practices. Most DHA access pathways are neutral, but two are material revenue leaks.

The new MetLife→DHA deal (Oct 2025) is the change to watch. DHA-contracted practices may see MetLife patients appear — at MetLife PDP rates — without any direct MetLife contract. Check your EOBs for MetLife payment activity starting Q4 2025.
Access Pathway Risk Matrix
Not all DHA access pathways create risk. The majority are mid-range carriers at comparable fee levels. The risk is concentrated in two carriers: MetLife (below-average) and Cigna (declining, ~40% w/o on new agreements).
