Delta is the largest dental carrier in the country, so most practices weigh joining its PPO or Premier networks early. Here is how contracting and credentialing actually work, what you get paid, and the volume-versus-margin trade behind the PPO decision.
Select a step to see the detail. The exact portal and forms depend on the Delta company that serves your state.
Delta does not pay your billed fee. It pays the lowest of your fee schedule, the maximum contract allowance for that ZIP, or the amount you submitted. Delta's own example: submit $120, allowance $100, everything is calculated on $100.
Allowances vary by 5-digit ZIP and by plan type (PPO allowances are usually lower than Premier), and Delta updates them roughly every 6 to 24 months. The difference between your full fee and the allowed amount is written off on covered services; the patient owes only their calculated share.
Descriptive, not a recommendation. The PPO decision is a business judgment for each office.
| Choice | Contracted fees | Steerage to your office |
|---|---|---|
| Premier only | Higher | Moderate |
| PPO only | Lower | Strongest |
| Both PPO and Premier | Depends on the member's plan | Broadest reach |
| Pathway | Delta partners with CAQH for credentialing and re-credentialing at no cost. Register or sign in to the CAQH Provider Data Portal, complete the profile, and authorize Delta to access it. |
| Documents | Active dental license and DEA where applicable, NPI, education and specialty history, malpractice insurance, work history, TIN/EIN, and disclosure of any disciplinary or malpractice history. |
| Timeline | Roughly 60 to 90 days, longer in some states. Start 90 to 120 days before your target date; you usually cannot bill in-network until it finishes. |
| Re-credentialing | CAQH re-attestation on a recurring cycle, with full re-verification about every three years. Keep the profile attested to avoid lapses. |
| Provider Tools | The online portal for eligibility, benefits, claims, pre-treatment estimates, payments, and practice updates. |
