NPI Registration and NPPES Record Management
The National Provider Identifier is the first identifier every enrollment depends on. We obtain Type 1 NPIs for individual providers and Type 2 NPIs for your organization, choose the right taxonomy codes, and keep the NPPES record aligned with every other system.

Want us to run it?
Send your roster and target payers; we map the gaps at no cost.
Getting an NPI is easy. Getting it right is not. The taxonomy code you select, the practice address you list and the way an individual NPI is linked to a group NPI all feed into Medicare, Medicaid and CAQH. A mismatch anywhere produces enrollment rejections and claim denials that are hard to trace back to their source.
ClainetRCM registers NPIs through NPPES with the correct provider type and taxonomy, sets up Type 2 NPIs for groups and facilities, and audits existing NPPES records so they agree with your licenses, PECOS and CAQH.
Where this usually goes wrong
Wrong taxonomy
A nurse practitioner registered under the wrong taxonomy, or a group registered as a solo provider, triggers enrollment rejections that reference codes nobody on staff understands.
No Type 2 NPI for the group
Practices billing under a group Tax ID need an organizational NPI. Billing individual NPIs against a group Tax ID causes payer rejections.
Stale NPPES addresses
NPPES is public and payers compare it to their records. An old address in NPPES can stall CAQH and PECOS applications.
What ClainetRCM handles
One coordinator owns the file from intake to effective date, so you always know who to call and what is outstanding.
- Type 1 NPI applications for physicians, NPPs, therapists and other individual providers
- Type 2 NPI applications for groups, facilities, labs and subparts
- Taxonomy code selection matched to license, specialty and payer requirements
- NPPES record audit and correction for existing NPIs
- Individual to group NPI linkage confirmed in PECOS and payer records
- Ongoing NPPES updates for address, name and taxonomy changes
Type 1 versus Type 2 NPI
| Type 1 | Individual providers: physicians, NPs, PAs, therapists, psychologists, dentists, chiropractors. One per person, for life, regardless of employer. |
|---|---|
| Type 2 | Organizations: group practices, clinics, hospitals, labs, DME suppliers, home health agencies. Tied to a Tax ID. Large organizations may register subparts. |
| Taxonomy | A code describing the provider type and specialty. Must match the license and the specialty you enroll under with each payer. |
| Where it is used | Every claim, PECOS, CAQH, Medicaid portals and payer applications. |
NPI registration is part of the sequence covered on our healthcare business registrations page, alongside entity formation, EIN and CLIA.
How the work runs
The sequence is the same for every payer and provider type; what changes is which documents and portals each step touches.
- 1
Intake and gap review
Licenses, DEA, board certificates, malpractice, work history and NPI details are collected and compared against what each target payer asks for.
- 2
Profile setup
CAQH ProView, PECOS and payer portals are created or cleaned up, attested and linked to the correct Tax ID and locations.
- 3
Application submission
Every enrollment is filed in dependency order, with a tracking record for each payer, date and reference number.
- 4
Follow-up on a fixed cadence
Payers are contacted on a schedule. Requests for more information are answered the same business day.
- 5
Approval, contract and handoff
Effective dates, provider IDs and fee schedules are logged and loaded into your billing system.
Frequently asked questions
Online applications through NPPES are often approved within a few business days, sometimes the same day. Paper applications take several weeks. We file online.
If the practice bills under its own Tax ID, yes, it needs a Type 2 organizational NPI. Each provider also keeps their individual Type 1 NPI, which is listed as the rendering provider on claims.
Yes, through NPPES at any time. If the change affects the specialty you are enrolled under, payers and PECOS need to be updated too, which we coordinate. See PECOS enrollment.
The NPI identifies a provider or organization for healthcare transactions. The Tax ID identifies the entity for tax and payment purposes. Claims carry both, and payers link them during enrollment.
