The superbill, with every field a plan’s claim system needs on it.
No law requires a superbill; an adjudication system does, field by field, and a missing one is a denial rather than a partial payment. Type the provider, the client, the diagnosis and one row per session, and print the receipt with the totals and the paid-in-full lines a refund depends on.
The fields →The fields
Provider, client, diagnosis.
The client’s name and date of birth must match the plan’s record exactly; a middle initial that differs is a real cause of denial. The diagnosis is a clinical act, not a billing convenience: a superbill needs one, and the honest choices are a diagnosis you can defend in the record or telling the client at intake that you do not produce superbills. The superbill page has the reasoning.
Why each field
The receipt has to survive a stranger’s system without you there.
Ten digits, free, from NPPES. A practice that never transmits a standard transaction is not required to have one; 45 CFR §162.410 says such a provider “may obtain, by application if necessary, an NPI.” Without it the superbill is unusable.
License type and number as the Board issued it; practice name, address and phone; your EIN, or SSN if you have no EIN. Plans verify the license.
Full name, date of birth and address matching the insurer’s record.
ICD-10-CM is the code set mandated under HIPAA; the FY 2026 edition took effect 1 October 2025. The CPT code is the minutes delivered, on the HHS-published ranges shown beside each code.
HHS: “POS 02 refers to telehealth provided other than in patient’s home and POS 10 refers to telehealth provided in patient’s home.” Modifier 95 for audio-video; HHS points to CPT modifier 93 for audio-only.
The charge per session and the total, and the amount paid with its date or an explicit “paid in full” per line.

Before you print one
Superbills, briefly.
What is a superbill?
A superbill is an itemized receipt formatted so that a client can send it to their own insurer and claim out-of-network reimbursement. It is not a claim: the client pays you, and the insurer reimburses the client. No law requires one, but a client with out-of-network benefits usually cannot be reimbursed without it.
What goes on a superbill?
The provider’s name, NPI and tax ID; the client; the diagnosis code; and, for each session, the date, the CPT code, the place-of-service code and any modifier, the fee, and what was paid. The generator above builds exactly that and prints it. The superbill and the good faith estimate, side by side →
