A bill for an act relating to health benefit plans, claims for reimbursement, and explanation of benefits.

HF 4 requires healthcare providers to submit claims for reimbursement to a patient's primary health insurance plan first, before submitting to any secondary plans. It also mandates that primary health plans must provide a copy of the "explanation of benefits" (EOB) to the patient, their representative, or a secondary plan within 30 days of a request. The bill directly affects patients, healthcare providers, and health insurance companies by standardizing claim submission order and improving access to EOB documentation. These provisions aim to streamline billing processes and reduce administrative delays for covered individuals. The bill is procedural, focusing on claim handling rules rather than altering health coverage benefits.
