Credentialing in Medical Billing: Process, Significance, and Best Practices
Credentialing of medical billing in today’s highly regulated medical health market is unavoidable and mandatory. As a solo practitioner or as an employee of a large practice, going credentialed ensures you’re certified to treat payers and patients for insurance for work done. Without the valuable process, delayed payments, denied claims, and non-compliance are threats to the financial success of a practice.
This guide will walk you through the provider credentialing process, explain why credentialing is so important to medical billing, and provide you with best practices in having your credentialing process done correctly and efficiently.
What is Credentialing in Medical Billing?
Credentialing is assurance that healthcare providers, physicians, nurse practitioners, or physician assistants are competent to practice medicine and receive reimbursement from insurance carriers. It involves verification of:
- Medical education and degrees
- Board certifications
- State licensure
- Work history
- Malpractice insurance
- DEA registration
- NPI number
Credentialing in revenue cycle management is important to ensure the provider is able to bill and receive payment for services. While some mix up enrollment with credentialing, they are not the same. Credentialing vs enrollment in healthcare is a two-part process that is separate but not unrelated: credentialing confirms qualifications, and enrollment formally places the provider on insurance providers’ lists so they can start billing.
Both processes are critical and must be handled with care and accuracy.
The Credentialing Process
The credentialing process cycle differs for every payer and provider type but typically ranges from 60 to 180 days. Delay at any stage can hinder a provider from bringing in revenue.
Step 1: Gather Documents Needed
Begin by stockpiling valuable content, such as:
- State medical licenses
- DEA certificate
- Malpractice insurance
- Board certifications and school transcripts
- Tax ID and NPI numbers
- Work history and peer references
These constitute the majority of the credentialing checklist for medical billing and must be correct and current.
Step 2: Submit Applications to Insurance Payers
Applications are submitted to Medicare, Medicaid, and commercial payers like Aetna, UnitedHealthcare, or Blue Cross Blue Shield. Accuracy here is paramount to avoid delay.
Step 3: Primary Source Verification
Insurance providers conduct a serious verification of all papers submitted directly with the source (e.g., medical schools, licensing commissions). Inconsistencies may prompt follow-up or denial.
Step 4: Committee Review
Credentialing committees review the provider’s credentials and decide on eligibility for inclusion in their network.
Step 5: Enrollment and Contracting
Approved, the provider is enrolled and signs on to a contractual agreement with the payer, legally authorizing them to bill for services provided.
Most practices utilize the medical billing and credentialing services in order to accomplish the task efficiently.

2. Utilize Credentialing Software
Invest in credentialing software in healthcare that will automate data gathering, monitor progress, and automatically remind for license renewals or expirations.
3. Maintain Centralized Credentialing File

4. Perform Internal Audits
Keep tabs periodically to ensure all provider files are current and compliant with credentialing requirements for healthcare providers.

Hiring medical billing and credentialing companies saves time and eliminates expensive mistakes, particularly for small or undermanned practices.
Most Frequent Issues and How to Avoid Them
Nursery-rhyme practices continue to face common credentialing challenges in healthcare. Below are how to avoid them:
1. Incomplete Applications
Solution: Utilize a comprehensive checklist and review each of them thoroughly before submitting them.
2. Failure to Follow Up
Solution: Appoint one staff person to monitor progress and follow up with payers from time to time.
3. Insurance Company Delays
Solution: Start early and make a record of all contacts.
4. Misunderstanding between Enrollment vs Credentialing
