A bill for an act relating to health insurers’ credentialing process.

HF 556 requires health insurers in Iowa to respond to credentialing requests from physicians, advanced nurse practitioners, and physician assistants within 56 calendar days. If an application is denied, insurers must provide a written explanation. Denied applicants can appeal internally and then to the insurance division, with "network adequacy" specifically listed as a valid appeal reason. The bill was introduced in 2025 but was withdrawn on March 21, 2025, and did not become law.
