For out-of-network providers, the superbill is the bridge between private-pay sessions and a client's insurance benefits. Here's what it is, what it must contain, and what it doesn't guarantee.
A superbill is an itemized receipt a healthcare provider gives a client after paying for services out of pocket. It lists the CPT codes for each service, the ICD-10 diagnosis code, dates of service, fees paid, and the provider's identifying details (NPI, license, tax ID). The client submits it to their insurance company to request out-of-network reimbursement. It is not a claim and does not guarantee payment — reimbursement depends on the client's out-of-network benefits.
Missing or mismatched details — an expired license number, the wrong NPI, a diagnosis that doesn't support the service — are the most common reasons payers reject superbill submissions.
| Who submits it | Superbill: the client submits to their insurer. Claim: the provider (or billing team) submits directly. |
|---|---|
| Network status | Superbills are an out-of-network workflow. In-network providers bill payers directly under their contract. |
| Who gets paid | Superbill: the client is reimbursed (they already paid you). Claim: the payer pays the provider. |
| Guarantee | Neither guarantees payment — but claims are adjudicated under a contract, while superbill reimbursement depends entirely on the client's out-of-network benefits and deductible. |
Set expectations before the first session: reimbursement only applies if the plan has out-of-network benefits (many HMO and Medi-Cal plans don't), an out-of-network deductible usually applies first, and the insurer reimburses a percentage of its "allowed amount" — not necessarily your full fee. Encouraging clients to call their plan and verify out-of-network mental health benefits avoids surprises. For clients whose plans won't reimburse, a single case agreement is sometimes an option.
A superbill is an itemized receipt a provider gives a client after the client pays out of pocket. It includes CPT service codes, ICD-10 diagnosis codes, dates, fees, and the provider's NPI, license, and tax ID. The client submits it to their insurer to request out-of-network reimbursement.
No. Reimbursement depends on whether the client's plan includes out-of-network benefits, whether the out-of-network deductible has been met, and the plan's allowed amount for each service. Plans without out-of-network benefits (many HMOs) typically won't reimburse superbills at all.
A claim is submitted by the provider directly to the payer, usually under an in-network contract, and the payer pays the provider. A superbill is given to the client, who submits it themselves and receives any reimbursement directly.
Provider name, credentials, license number, NPI, tax ID, and practice address; the client's name and date of birth; an ICD-10 diagnosis code; and for each session, the date, CPT code (e.g., 90834 or 90837), any modifiers, duration, and the fee paid.
