Group NPI vs Your Own NPI: Do You Own Your Insurance Contracts on Headway and Alma?

## **Group NPI vs individual NPI: what is the difference?** **A National Provider Identifier (NPI) is a unique 10-digit number issued through the NPPES system run by CMS, used to identify you in standard insurance claim transactions (CMS).** There are two kinds, and the distinction sits at the center of who owns your contracts. An individual NPI (Type 1) belongs to you, the clinician, for life. A group or organizational NPI (Type 2) belongs to a practice or company. When you bill insurance, the claim carries an NPI, and the payer contract that governs that claim is tied to whichever NPI was credentialed. On a platform that credentials you under its group NPI, your claims go out under the platform's Type 2 number. The in-network agreement is between the insurer and the platform. You are added as a rendering provider inside that agreement, not as the contract holder. Billing under your own NPI flips this. Your individual Type 1 NPI, paired with your own Tax ID, holds the payer contract directly. The agreement is between the insurer and your practice, so it stays with you regardless of which software or billing service you use. ### Why the NPI on the claim matters The NPI on a submitted claim is not a formality. It tells the payer which contract, and which negotiated rate, applies to that visit. Change the controlling NPI and you are operating under a different contract, often one you have to credential for from scratch.

## **How do platforms like Headway and Alma credential you?** Platforms like Headway and Alma typically credential you under their group NPI. You join the network, the platform handles the insurance side, and your sessions are billed through the platform's payer contracts rather than contracts held in your own name. This is a real convenience, especially early in private practice. The platform absorbs the credentialing paperwork, the claim submission, and much of the billing follow-up, and you start seeing insured clients sooner than solo credentialing usually allows. The trade-off is structural. Because the contracts live with the platform, the platform controls the relationship with the insurer, including the rate you are paid and the terms under which you are paid. ### Headway: how the model and cost work Headway does not charge therapists a separate stated fee. Its margin comes from the difference between what insurers pay and the per-session rate it pays the therapist, and that difference is not shown to the therapist as an itemized line. Rate visibility is limited, and the network is mental-health focused. That structure is worth understanding before you build a practice on it. You are not paying an invoice you can see, but the economics still run through a contract you do not hold and a spread you cannot inspect. ### Alma: what is publicly observable Alma operates as a mental-health membership platform that, like other group-NPI networks, credentials participating clinicians within its own insurance relationships. We keep this at the category level on purpose: specific Alma fee and contract mechanics are not something to assert without a cited source, so treat the group-NPI structure, not any one platform's terms, as the thing to evaluate. The point that holds across these platforms is the same. Verify who holds the contract before you rely on it for your income.

## **What do you keep if you leave a platform?** If you leave a platform that credentialed you under its group NPI, you generally keep your individual NPI and your license, but not the in-network contracts. Those agreements belong to the platform, so your in-network status with each insurer does not transfer, and you typically re-credential under your own NPI before billing those payers again. Here is what that means in practice across the three things clinicians worry about most. - **Your credentials and license:** Yours already. Your individual NPI and state license are never the platform's to keep. - **Your in-network contracts:** Usually the platform's. Leaving means you are out-of-network on those panels until you credential independently. - **Your clients:** Yours to contact, but their insurance coverage of your sessions can lapse the moment you are no longer in-network through the platform, which can force a mid-care conversation about cost. The re-credentialing gap is the hidden cost. Credentialing under your own NPI commonly takes 60 to 180 days depending on the payer (Verisys, 2026), and during that window insured clients may have no in-network way to keep seeing you.

## **Group NPI vs your own NPI: the ownership comparison** The clearest way to see the decision is side by side. The list below compares a platform that credentials you under its group NPI against billing under your own NPI, across the five things that determine ownership. - **Who holds the contract.** Platform (group NPI): the platform; you are a rendering provider inside its agreement with the insurer. Your own NPI: your practice, with the agreement between you (individual NPI plus your Tax ID) and the insurer. - **Rate visibility.** Platform: limited; on a network like Headway, the spread between insurer payment and your per-session rate is not itemized. Your own NPI: full; you see the payer's contracted allowed amount and your reimbursement directly. - **What you keep if you leave.** Platform: your license and individual NPI, but not the in-network contracts, which stay with the platform. Your own NPI: the contracts, the credentialing, and the in-network status, because they are in your name. - **Re-credentialing to switch.** Platform: usually required; you credential from the start under your own NPI before billing those payers again. Your own NPI: not triggered by switching software or billing services, because your existing contracts carry over. - **Scope.** Platform: network-defined; Headway is mental-health focused, so you bill within the platform's payer relationships. Your own NPI: you choose which payers to enroll with and bill them across the categories you are credentialed for. The pattern is consistent. The group-NPI model trades ownership for convenience. The own-NPI model keeps ownership, and the convenience can be added back through a billing service that works under your number.

## **How do you bill insurance under your own NPI?** To bill under your own NPI, you credential directly with each insurer using your individual NPI and Tax ID, then submit claims under that number, either yourself or through a billing service acting as your agent. The contracts stay in your name throughout. There are two routes, and they are not mutually exclusive. 1. **Do it yourself.** Get an individual NPI through NPPES, complete and attest your CAQH ProView profile, and apply to each payer you want to join. Then handle eligibility checks, claim submission, denials, and posting in-house. The full process is covered in our guide on [how to get credentialed with insurance companies](https://www.carepatron.com/blog/how-to-get-credentialed-with-insurance-companies/). 2. **Use a managed billing service under your NPI.** A full-service revenue cycle management provider can credential you and then run the day-to-day billing on your behalf, from claim submission through denials and patient statements, while the contracts remain in your name. You get the platform-style convenience without handing over ownership. The distinction that matters is the agency relationship. A service that bills under your own NPI is acting as your agent, so your contracts and credentialing belong to you. A platform that bills under its group NPI is the contract holder, and you are inside its agreement. **Carepatron bills under your own NPI and Tax ID, so your payer contracts and credentialing stay yours if you ever leave.** If you are weighing this against keeping billing in-house, our breakdown of [in-house vs outsourced medical billing](https://www.carepatron.com/blog/in-house-vs-outsourced-medical-billing/) lays out the cost and control trade-offs.

## **Frequently asked questions** ### Do you own your insurance contracts on Headway? On Headway, you generally do not own the insurance contracts. Headway credentials therapists within its own network, so the in-network agreement sits with the platform. You keep your individual NPI and license, but your in-network status on those contracts does not transfer if you leave. ### What happens to my insurance panels if I leave a platform? If you leave a platform that credentialed you under its group NPI, your in-network status on those payer contracts usually does not come with you. You keep your individual NPI and license, but you typically re-credential under your own NPI, which commonly takes 60 to 180 days per payer (Verisys, 2026). ### What is the difference between a group NPI and an individual NPI? An individual NPI (Type 1) identifies you, the clinician, and is yours for life. A group NPI (Type 2) identifies a practice or company. The payer contract follows whichever NPI was credentialed, so the controlling NPI on your claims determines who owns the insurance agreement. ### Can I move my insurance contracts from a platform to my own practice? You cannot transfer a contract held under a platform's group NPI into your own name. You credential separately under your own individual NPI and Tax ID, which creates a new agreement directly between you and each insurer. Once credentialed, that contract is yours and is not tied to any platform or software. ### Do I have to re-credential if I switch billing software or services? No. If your contracts are held under your own NPI and Tax ID, changing billing software or services does not trigger re-credentialing. A billing service acts as your agent and submits claims under your number, so your existing payer agreements stay intact through the switch. ### Is billing under my own NPI worth the extra credentialing time? It depends on how long you plan to practice. Credentialing under your own NPI takes 60 to 180 days per payer (Verisys, 2026), but the contracts then belong to you. Clinicians building a long-term practice often prefer owning the infrastructure over renting access through a platform.
