Key takeaways
- NPI identifies you, CAQH feeds commercial payers, and PECOS holds your Medicare enrollment.
- Re attest CAQH every 120 days and authorize each payer to view the profile.
- Keep name, address, and taxonomy consistent across all three and your license.
New providers hear three acronyms in their first week: NPI, CAQH, and PECOS. They are separate systems run by different organizations, and payers check all of them. When they agree with each other, enrollment moves. When they do not, it stalls. This guide explains each one in plain terms.
NPI: your national identifier
The National Provider Identifier is a 10 digit number issued through NPPES, the federal system run on behalf of CMS. Every provider who bills electronically needs an individual NPI, often called Type 1. A group practice also needs an organizational NPI, called Type 2. The NPI never changes, but the information attached to it does, so update NPPES when you move, change your mailing address, or change your taxonomy.
- Type 1 NPI: the individual provider.
- Type 2 NPI: the practice or group that bills.
- Taxonomy code: the specialty recorded on the NPI. It should match how you plan to bill.
CAQH ProView: the profile commercial payers read
CAQH ProView is an online profile where providers enter their education, training, licenses, work history, malpractice coverage, and practice locations once. Most commercial payers and many Medicaid managed care plans pull credentialing data from it instead of asking for separate paper packets. Two things matter most:
- Authorize each payer to view the profile. If a payer is not authorized, it cannot see your data.
- Re attest every 120 days. CAQH asks providers to confirm the profile is current on that cycle, even when nothing changed. If the attestation lapses, payers cannot use the profile until it is renewed.
PECOS: Medicare enrollment
PECOS is the CMS online system for Medicare provider enrollment. Providers use it to enroll in Medicare, reassign benefits to a group, update practice information, and revalidate. Most providers revalidate their Medicare enrollment about every five years, and CMS can also request off cycle revalidation, so the record needs attention even after approval. A provider who orders or refers services for Medicare patients may also need an active PECOS record so those orders are accepted.
How the three fit together
Think of the NPI as the identifier, CAQH as the profile for commercial plans, and PECOS as the Medicare record. A payer reviewing an application may compare all three against the state license. The most common problems are simple: a different spelling of the name, an old practice address, or a taxonomy that does not match the specialty on the application.
A starter checklist for new providers
- Confirm your individual NPI and check that NPPES shows your current address and taxonomy.
- Get the group NPI and tax ID details from the practice you are joining.
- Create or update your CAQH profile, upload documents, authorize payers, and attest.
- Enroll in Medicare through PECOS or reassign benefits to the group, if the practice sees Medicare patients.
- Enroll with your state Medicaid program if the practice accepts Medicaid.
- Keep a calendar for CAQH attestation, license renewals, malpractice renewals, and Medicare revalidation.
Do not put patient information in emails or website forms when you share enrollment documents. Use a secure method agreed with your practice or billing partner.
Common mistakes to avoid
- Using a home address on NPPES that does not match the practice location on applications.
- Forgetting to authorize a new payer in CAQH after applying to it.
- Leaving gaps in work history without a short explanation.
- Letting a malpractice certificate or license expire in CAQH after renewing it in real life.
Where Afiable helps
Afiable sets up and maintains CAQH, supports NPI and PECOS updates, prepares Medicare, Medicaid, and commercial applications, and tracks expirations so nothing lapses quietly. If you are a new provider or adding one, book a free audit and we will check that all three records line up before you apply.
Questions practices ask
Do I need PECOS if I do not bill Medicare?
If you order or refer services for Medicare patients, such as labs, imaging, or therapy, you may still need an active PECOS record so those orders are accepted. Check with the practice before deciding.
What happens if my CAQH attestation expires?
Payers cannot use the profile until you attest again. Applications and re credentialing can stall in the meantime, so set a reminder before the 120 day mark.
