Superbill

A superbill is an itemized receipt from a provider that a patient can submit to their insurance plan themselves for out-of-network reimbursement. It includes the date of service, the provider's NPI and tax ID, the CPT codes for services rendered, the ICD-10 diagnosis codes, and the amount paid. Common in specialties where many providers stay out-of-network by design — mental health, functional medicine, some pediatric subspecialties.

The workflow: the patient pays the provider directly at the time of service, the provider issues a superbill, the patient submits the superbill to their insurer as an out-of-network claim, and the insurer reimburses whatever their out-of-network benefit allows — typically after the out-of-network deductible is met, at whatever percentage the plan pays for OON care. It's slower and messier than a normal in-network claim, and the reimbursement is usually less than the amount paid, but it's still real money back. Some plans require additional documentation (session notes for therapy, treatment plans for chronic care) before reimbursing.

The takeaway: if you're seeing an out-of-network provider by choice, always ask for a superbill and submit it to your plan. Even a partial reimbursement helps, and the amount paid counts toward your out-of-network deductible and out-of-pocket maximum.
