A credentialing denial means the plan reviewed your record against its standards and turned you down; it usually comes with rights to review your file, correct errors and request reconsideration. A network denial means the plan decided it has enough providers of your type; the main rights are a written reason and, in some states, a review or fair-opportunity rule.
Two providers apply to the same health plan in the same month. One receives a letter saying the plan's credentialing committee has declined her participation. The other receives a letter saying the plan's network for his specialty is adequate in his county and it is not offering a contract. Both feel like the same "no." They are not, and the difference decides almost everything about what happens next.
What does each kind of denial decide?
A credentialing denial is a judgment about you. The plan verified your license, education, malpractice history, work history, privileges and sanctions against its written standards and decided you do not meet them, or that a committee should not make an exception. Medicare Advantage plans must run this review under written policies that include "verification of licensure or certification from primary sources, disciplinary status, eligibility for payment under Medicare, and site visits as appropriate" (42 CFR 422.204(b)(2)(i)).
A network denial (also called a contracting denial or a closed panel) is a judgment about the plan's network. Nobody looked at your record, or the plan looked only far enough to see your specialty and address. The plan decided it does not need more providers of your type there, which Medicare Advantage and Medicaid managed care rules both allow (42 CFR 422.205(b)(1); 438.12(b)(1)).
Who makes each decision?
| Credentialing denial | Network denial | |
|---|---|---|
| Decided by | Credentialing committee or medical director | Network management or contracting |
| Based on | Your record against written criteria | Counts of providers by specialty and county |
| Usual timing | After verification, at a committee meeting | Often before credentialing starts |
| Typical internal remedy | Reconsideration, review and correction of your file | Usually none written |
| Main outside lever | State credentialing law; the state's uniform Medicaid policy | Network adequacy rules; state fair-opportunity or any willing provider laws |
Which rights come with a credentialing denial?
Credentialing denials tend to carry more process, because accreditation standards and plan policies build it in. A Medicaid plan's credentialing policy filed with the Louisiana Department of Health (Louisiana Healthcare Connections, LA.CRED.01, revised December 2022) is a useful example. It gives practitioners the right to:
- review information the plan obtained to evaluate the application, on a written and signed request, excluding references, recommendations and peer-review protected material, with the information sent "within fourteen (14) days";
- learn the status of the application "at any time";
- correct "any erroneous information submitted by another party";
- request reconsideration "within thirty (30) calendar days of the date of receipt of the denial letter" when denied "for non-administrative reasons," with the request heard at the next committee meeting and no later than 60 calendar days after receipt of the additional information.
The same policy says a denial letter "includes the reason and information on the practitioner's right to view and/or correct erroneous information," and that a denied applicant may reapply "no earlier than one (1) year following the initial denial or end of the reconsideration process." Your plan's numbers may differ; the shape is common.
For Medicaid plans there is also a state yardstick. Each state must "establish a uniform credentialing and recredentialing policy" that every Medicaid plan in the state follows (42 CFR 438.214(b)(1)). A credentialing denial that departs from the state's policy is a stronger complaint to the state Medicaid agency than a generic objection. See each state's uniform Medicaid credentialing policy.
Which rights come with a network denial?
Fewer, and they come from regulation rather than the plan's own policy:
- A written reason. Required of Medicare Advantage plans (422.205(a)) and Medicaid managed care plans (438.12(a)(1)), and of Texas PPO insurers (Tex. Ins. Code 1301.051(c)).
- A review panel, in Texas PPOs. An insurer that does not designate a practitioner as a preferred provider must offer a review mechanism with an advisory panel of at least three participating practitioners, including one in the same or similar specialty if available (Tex. Ins. Code 1301.053). The insurer may still reject an applicant because the plan "has sufficient qualified providers" (1301.051(d)). See the Texas fair opportunity law.
- A state any willing provider law, in the few states that have one for providers generally. See any willing provider laws.
- Network adequacy. Not a right of yours, but an obligation the plan owes its regulator, which your evidence can bring into play. See how to write a network adequacy letter.
For Medicare Advantage, the participation appeal process in 42 CFR 422.202(a)(4) is aimed at "adverse participation procedures," and the hearing with a peer panel described in 422.202(d) applies to suspension and termination of an existing contract. CMS's manual describes hearing rights for "Suspension, Termination, or Nonrenewal" (Medicare Managed Care Manual, Chapter 6, section 60.4). A first-time applicant turned away for network size should expect a written reason, not a hearing. See Medicare Advantage adverse participation decisions.
Why does mixing them up cost so much?
Three mistakes come up again and again:
- Treating a credentialing denial like a closed panel. The provider writes to network management about community need, misses the 30-day reconsideration window in the credentialing policy, and inherits a one-year reapplication bar.
- Treating a closed panel like a credentialing denial. The provider sends malpractice certificates and reference letters to a contracting team that never doubted them. Nothing in the letter addresses why the plan thinks it does not need another provider.
- Treating an administrative closure as either. The file was closed for a missing document. No dispute is needed; the file needs curing and resubmitting, quickly.
How can you tell from the letter?
Look for the sender (credentialing department or contracting), for references to a committee, for language about "network need," "adequacy" or "sufficient providers," and for any mention of review, reconsideration or a deadline. If the letter is vague, ask the plan in writing which decision it made and why. Medicare Advantage and Medicaid plans must answer the "why." Our post on why payers reject providers walks through all four buckets.
Can we sort it out for you?
Yes. A Network Rejection Review ($249, credited toward a dispute) classifies each letter, identifies the plan type and the rights that come with it, and puts every deadline on a calendar. If a dispute has a lever, a Payer Network Dispute ($799 per payer) prepares the reconsideration request or the access-gap package for you to sign and send. We are not a law firm and do not give legal advice. If a matter needs a lawyer, you hire a healthcare attorney directly.
Common questions
- How do I know if I was denied credentialing or denied a contract?
- Check who sent the letter and what it cites. A credentialing committee or medical director, and references to your record, point to credentialing. Contracting or network management, and words like network need or adequacy, point to a network denial. If it is unclear, ask the plan in writing.
- Do I get an appeal if the panel is closed?
- Usually not a formal one. Medicare Advantage and Medicaid plans must give a written reason. Texas PPO insurers must offer a review with an advisory panel. Otherwise, the leverage comes from network adequacy evidence and state law rather than an appeal right.
- How long do I have to ask for credentialing reconsideration?
- It depends on the plan. One Louisiana Medicaid plan allows 30 calendar days from receipt of the denial letter. Read your letter and the plan's provider manual, and calendar the deadline the day the letter arrives.
- Can a plan deny me for both reasons?
- Yes. A plan can close a file as administratively incomplete and later say the network is full, or credential you and then decline to contract. Each decision is answered separately, which is why the letters need to be read closely.
