Superbill
A superbill is an itemized encounter form listing the provider's details, diagnosis codes, CPT codes, and charges for a visit. Practices use it internally to capture charges; out-of-network and cash-pay patients submit it to their insurer for direct reimbursement. A complete superbill needs NPI, tax ID, ICD-10, CPT, and fees at minimum.

What is a superbill and who actually uses it?
A superbill is the coded summary of an encounter, and it lives a double life. Inside an insurance-based practice it is the charge ticket: the provider circles or clicks the CPT and diagnosis codes, and the billing team turns that into a claim. In cash-pay and out-of-network practices, especially mental health, PT, and concierge medicine, the superbill goes home with the patient, who submits it to their insurer for reimbursement under out-of-network benefits.
Either way, the superbill is where charge capture succeeds or fails. If a service is not on the superbill, it never becomes revenue.
What information must a superbill include?
A payer-ready superbill needs everything an adjudication system would pull from a CMS-1500:
- Provider name, credentials, NPI (individual and group), and tax ID
- Practice address and phone (the physical service location, not a PO box)
- Patient name, date of birth, and date of service
- ICD-10 diagnosis codes, linked to each service line
- CPT/HCPCS codes with units and the fee charged per code
- Place of service code and amount the patient paid
Keep the fees synchronized with your chargemaster. A superbill showing $150 for a code your system bills at $175 creates reconciliation noise and, for OON patients, underpays them.
How do out-of-network patients use a superbill?
Worked example: a patient sees an out-of-network therapist weekly and pays $160 per session for 90837 (60-minute psychotherapy). Their PPO has a $1,000 out-of-network deductible, then pays 60% of a $130 allowed amount. The patient submits monthly superbills; after roughly six sessions ($780 applied to the deductible at the allowed rate, plus the gap) the deductible is met, and each later session returns about $78 (60% of $130). Over a 40-session year that is roughly $2,600 back, entirely dependent on the therapist handing over a properly coded superbill.
Tell patients to photograph and submit superbills monthly, and to watch the resulting EOB so denials get corrected inside the payer's member timely filing window, commonly 90 to 365 days (see the timely filing limits table).
Where do superbills go wrong?
The classic failure is the stale template. Practices print superbill templates once and let them fossilize: deleted CPT codes linger for years, new codes never get added, and providers default to whatever is on the sheet. That is how a practice ends up billing a deleted code all January or systematically missing a billable service that was added to CPT two years ago.
Frequently asked questions
No. A superbill is the source document; a claim is the standardized format (CMS-1500 or 837P) actually submitted to a payer. Internally, a biller translates the superbill into a claim. For out-of-network care, the patient submits the superbill with the payer's member claim form, and the payer adjudicates from it.
Provider name, NPI, tax ID (EIN), practice address, patient name and date of birth, date of service, ICD-10 diagnosis codes, CPT/HCPCS codes with charges per code, place of service, and proof of payment if the patient paid up front. Missing any of these is the top reason member-submitted claims get returned.
They are not federally required to unless the patient requests documentation, but most therapy, psychiatry, and concierge practices provide them routinely because patients use them for out-of-network benefits and HSA/FSA substantiation. If you opted out of Medicare, superbills to Medicare patients must reflect that Medicare cannot be billed.
Almost never. A credit card receipt lacks diagnosis and procedure codes, so the payer cannot adjudicate it. Payers routinely deny or pend member claims submitted with receipts alone and request a coded superbill, which delays reimbursement by 30 to 60 days.
