What providers miss in Delaware
- The 2028 law still lets carriers choose not to contract with a credentialed clinician; it governs credentialing, not network selection.
- From 2028, claims for services after a complete application are payable once credentials are granted, but cannot be submitted until the carrier gives the effective date.
- A network adequacy complaint puts the burden on the plan, which is unusual and worth using in a documented access-gap letter.
Does Delaware have an any willing provider law?
No provider-wide any willing provider statute was confirmed for Delaware.

- Deadline: 30 days
- Applies to: All carriers, including HMOs, TPAs and, as federal law allows, Medicaid managed care plans; health-care professionals. Takes effect January 1, 2028.

Can a provider practice in network while Delaware plans credential them?
From 2028, provisional credentials run from the clean-application notice when the carrier misses its deadline, or when the clinician works mainly in a shortage area or FQHC, is already credentialed by the carrier elsewhere in Delaware, or is moving from a reciprocal state. Recent malpractice settlements or discipline bar it.
- Provisional or interim credentialing
Citation: Del. Code tit. 18, § 3308B
What network adequacy rules apply in Delaware?
Managed care organizations must keep enough primary care, specialist and ancillary providers at all times. If providers are not geographically accessible or available in a reasonable time, the plan must cover non-network providers without balance billing.
Citation: 18 Del. Admin. Code 1403, § 11.3
Burden of proof on the plan
When the Department receives a complaint about a managed care organization's network adequacy, the plan bears the burden of proving its network is adequate.
Citation: 18 Del. Admin. Code 1403, § 11.3.4
Written reasons and a peer hearing for credentialing denials (2028)
From 2028, a carrier may not deny, suspend, nonrenew or terminate credentials without a written explanation and notice of the right to request, within 30 days, a hearing before a panel that includes a clinical peer. Violations can bring damages of up to $500 per day of delay, capped at $5,000 per incident.
Citation: Del. Code tit. 18, §§ 3310B, 3311B

Turned down by a plan in Delaware?
We read the denial, check which of these rules reach that plan, and prepare the reconsideration request, the access-gap evidence and any regulator complaint the law supports; you sign and send them, and we track every deadline. Self-funded employer plans follow federal law, not Delaware's. A rejection review is $249, credited toward a dispute.
