Credentialing & Payer Enrollment

Credentialing is the process of verifying a provider's background, licenses and training. Payer enrollment is the separate step of getting approved to bill a specific health plan. A provider usually cannot be paid by a plan until both are done, so delays here hold up revenue.

Outsourced credentialing services take the paperwork and follow-up off your team. Westmont Revenue Partners connects practices and facilities with vetted medical billing experts who handle applications, track status with each payer, and keep records current. A credentialing company can be especially helpful when a new provider joins or a group opens another location.

Who this is for

• New practices enrolling with payers for the first time
• Groups adding physicians, nurse practitioners, therapists or other clinicians
• Providers moving between practices or states
• Practices opening new locations or changing tax IDs
• Facilities that must keep many providers current for re-credentialing
• Practices with a payer application that has stalled

What's included

• Gathering licenses, certificates, work history and malpractice information
• Setting up and maintaining the provider's online profile with payers and shared data sources
• Medicare enrollment applications and updates
• Medicaid enrollment applications where applicable
• Commercial payer applications and contracting requests
• NPI record review and updates
• Tracking application status and following up with payers
• Re-credentialing and revalidation reminders
• Monitoring license, DEA and board certification expiration dates
• Updating practice location, group and billing details
• Keeping a record of effective dates and provider identifiers

How it works

1. You share your provider list, locations, tax IDs and the payers you want to join.
2. Westmont matches you with a credentialing specialist with experience in your specialty and region.
3. The specialist collects documents, fills in applications and submits them.
4. The specialist follows up with each payer and reports on status.
5. Once approved, effective dates and identifiers are recorded and shared with your billing team.
6. Renewal and update dates are tracked so enrollment does not lapse.

Common challenges

• Incomplete applications. Missing or mismatched details cause rejections and restarts. Experienced specialists check every field against source documents before submitting.
• Slow payer response. Payers may take a long time to act. Specialists keep a follow-up log and escalate through provider relations contacts.
• Effective date gaps. Services may not be payable before the effective date. Good specialists ask about retroactive options early and advise on scheduling plans.
• Data that does not match. Differences in name, address or taxonomy between records can stall approval. Specialists align records before applying.
• Missed re-credentialing. Deadlines slip by unnoticed. A tracking calendar with advance reminders prevents lapses.
• Group versus individual enrollment. Payers handle linking providers to groups differently. Specialists know to confirm that each provider is tied to the correct billing entity.
• Telehealth and multi-state licensing. Providers who see patients across state lines need coverage in each place. Specialists review requirements for each state and payer.

Metrics worth tracking

• Applications in progress by payer: shows where work is waiting
• Time to effective date: shows how long enrollments take in practice
• Application rejection rate: points to data quality problems
• Providers billing-ready: shows who can be scheduled for each payer
• Upcoming expirations: shows licenses and re-credentialing dates due soon
• Claims denied for enrollment reasons: shows gaps between credentialing and billing

Frequently asked questions

What is the difference between credentialing and payer enrollment?

Credentialing verifies a provider's qualifications, such as licenses, education and work history. Payer enrollment, sometimes called contracting or participation, is the approval to bill a health plan and be paid at its rates. Plans often require credentialing first. Both steps need tracking, and both affect when you can bill.

How long does credentialing take?

It varies by payer, state and how complete the application is. Some plans move faster than others, and delays are common. Plan ahead and begin early, ideally before the provider's start date. A credentialing company can give you a realistic view based on the payers you use.

Can a provider see patients before enrollment is approved?

That depends on the payer and the situation. Some plans pay for services only from the effective date, and out-of-network rules may apply. Ask each payer about its policy and plan the schedule with that in mind. A credentialing specialist can help you check before booking patients.

Do providers need to be re-credentialed?

Most payers require periodic re-credentialing, and Medicare requires revalidation on a schedule set by CMS. Dates differ by plan. Outsourced credentialing services track these dates so you do not lose participation by missing a deadline.

What information do I need to start?

Expect to provide licenses, board certifications, malpractice coverage, work history, NPI and tax ID details, and practice location information. Having these in one folder speeds things up. Your matched specialist will give you a checklist for each payer.
