Colorado's Credentialing Deadlines

Colorado's 2021 credentialing law, Senate Bill 21-126, put specific day counts on how carriers handle physician applications, and it attached a consequence to one of them that most states never adopted: if a carrier fails to send a receipt for a completed application within seven days, the physician is treated as participating no later than day 53. The law is narrower than many providers assume, though. It applies to physicians, not every clinician.

What do the deadlines require?

SB21-126 added section 10-16-705.7 to the Colorado Revised Statutes. As enacted, it requires:

• A receipt in 7 days. "Within seven calendar days after a carrier receives an application, the carrier shall provide the applicant a receipt in written or electronic form" (10-16-705.7(2)(a)).
• An incompleteness notice in 10 days. The carrier must "promptly determine whether the application is complete" and, if not, notify the applicant "within ten calendar days after the date the carrier received the application," describing the missing items (2)(b).
• A decision in 60 days. "A carrier shall conclude the process of credentialing an applicant within sixty calendar days after the carrier receives the applicant's completed application" (3)(a).
• Notice of the outcome in 10 days after credentialing concludes (3)(b).

What happens if the carrier never sends a receipt?

"If a carrier receives a completed application but fails to provide the applicant a receipt in written or electronic form within seven calendar days after receiving the application ... the carrier shall consider the applicant a participating physician, effective no later than fifty-three calendar days following the carrier's receipt of the application" (10-16-705.7(2)(c)).

That trigger is specific. It turns on the missing receipt for a completed application, not on missing the 60-day deadline. So the documents to keep are proof of what you submitted, when the carrier received it, and whether a receipt came within seven days.

Who does the law cover?

"Applicant" means "a physician who submits an application to a carrier to become a participating physician," and "physician" means one licensed under Article 240 of Title 12 (10-16-705.7(1)(a) and (1)(i)). Psychologists, counselors, social workers, therapists and nurse practitioners are outside this section as enacted. The act applies to applications submitted on or after its effective date in 2021 (SB21-126, section 3(2)).

The usual limits also apply: self-funded employer plans are generally outside state insurance law because of ERISA, and Medicare Advantage follows federal rules.

Which other duties come with it?

• Your file. After a decision, the carrier must give the applicant, on request and as allowed by law, "all nonproprietary information pertaining to the application and to the final decision" (3)(c). That is the starting point for any reconsideration.
• Published rules. Carriers must post their credentialing policies and procedures, the information required in an application, a checklist of materials, a designated contact with email and phone, and the commissioner's authority to enforce the section (7).
• Directory fixes. Carriers must correct directory discrepancies within 30 calendar days of a report from a participating physician, and physicians must report changes in name, address, phone, business structure or tax ID within 15 business days (5).
• Recredentialing without reapplying. A carrier "shall not require a participating physician to submit an application or participate in a contracting process in order to be recredentialed" (8)(b).
• Claims after credentialing. A carrier may not deny a claim for a medically necessary covered service by a participating physician who is in network and "has concluded the carrier's credentialing process" (6).

Two deeming rules can change the analysis. A carrier with a delegated credentialing agreement with a health care facility that imposes equivalent or higher requirements is deemed compliant for applicants who work for that facility, and so is a carrier in a carrier credentialing alliance with equivalent or higher requirements (4).

Who enforces it?

"The commissioner shall enforce this section." On receiving "more than one complaint from an applicant or a participating physician alleging a violation of this section by a carrier, the commissioner shall investigate the complaints," and a noncompliant carrier is subject to civil penalties under section 10-1-310 (10-16-705.7(10)). That makes the Colorado Division of Insurance a real forum for a missed deadline, which is unusual. It is still a timeliness rule: it does not require a carrier to contract with you.

Does Colorado Medicaid have its own deadline?

Yes, by contract. UnitedHealthcare's State and Federal Regulatory Addendum (revised 9/2026) restates the Colorado Medicaid contract: plans must "complete the credentialing and contracting processes or deny network admission within ninety (90) days for at least ninety percent (90%) of all Provider applications," measured from the provider's written request to contract and ending on a signed contract or a formal denial. Back-dating a contract does not count. Plans must deny an application that is not complete within 80 days, after notifying the provider, and must respond to credentialing and contracting inquiries within two business days. Network providers must be enrolled with the state as Medicaid providers.

How to use Colorado's rules

1. Submit a complete application and keep proof of the receipt date.
2. Note whether a receipt arrives within seven days. If not, write to the carrier on day 54 stating that it must consider you participating under 10-16-705.7(2)(c).
3. If the 60 days pass, ask for a decision in writing, then request your nonproprietary file after any denial.
4. If the carrier does not respond, a complaint to the Division of Insurance is an option the statute specifically contemplates.

How we help

We research, prepare and organize; we are not a law firm. A Network Rejection Review ($249, credited toward a dispute) checks your dates against each Colorado deadline. A Payer Network Dispute ($799 per payer) prepares the day-54 or day-61 letter, the file request and a Division of Insurance complaint draft, all for you to sign and send, and we track the replies. A credentialing approval or contract carries a flat $1,500 win fee. Legal questions go to a Colorado healthcare attorney. See our Colorado page and credentialing deadline laws by state.
