Medical Credentialing for Group Practices: Common Pitfalls and How to Avoid Them

Medical credentialing is the backbone of every healthcare practice’s revenue cycle—but for group practices, the process can be significantly more complex. When you’re credentialing multiple providers across various locations, each with different specialties and payers, even small mistakes can result in delays, denials, compliance issues, and lost revenue.

Whether you're launching a new group practice, expanding your provider roster, or just trying to tighten your operations, understanding the common pitfalls of credentialing—and how to avoid them—is essential to keeping your organization efficient, compliant, and profitable.

Why Credentialing Matters More in Group Practices

Group practices depend on every provider being enrolled and in-network with key payers. If one provider is not properly credentialed:

  • Claims for that provider may be denied

  • Your practice might not get paid for months

  • Patients may lose access to in-network care

  • Your compliance risk increases

  • Your reputation with payers could be impacted

Unlike solo practices, group practices often deal with:

  • A higher volume of credentialing requests

  • Complex NPI and tax ID linkages

  • Frequent provider onboarding and turnover

  • Multi-state or multi-location logistics

This makes the risk of credentialing errors even greater—and the impact even more costly.

Common Credentialing Pitfalls for Group Practices

1. Starting the Credentialing Process Too Late

One of the most common and costly mistakes is waiting until after a provider is hired to start credentialing. Since it can take 60–120 days (or longer) to get fully credentialed with each payer, any delay in starting the process creates a significant revenue gap.

How to Avoid It: Start the credentialing process immediately after the provider signs their contract. Use a standard intake packet to collect all necessary documentation upfront, including:

  • NPI (Type 1)

  • Licenses and board certifications

  • DEA registration (if applicable)

  • Malpractice insurance

  • CV and work history

  • CAQH profile access

2. Confusing Group and Individual Enrollment

Many group practices mistakenly assume that credentialing the group alone is enough. In reality, both the practice (Type 2 NPI) and each individual provider (Type 1 NPI) must be enrolled and linked correctly with each payer.

How to Avoid It: Ensure that every payer has both your group NPI/tax ID and each provider enrolled and linked to your group contract. This is essential for claims to process correctly.

3. Missing or Mismatched Information

Credentialing is highly detail-oriented. Something as small as an address mismatch between your CAQH profile and a payer application can stall approval.

How to Avoid It: Create a centralized credentialing profile or master application with consistent data for all providers and locations. Always double-check that information is aligned across:

  • CAQH

  • PECOS (for Medicare)

  • Payer portals

  • Internal HR and billing systems

4. Ignoring Re-Credentialing and Expiration Dates

Credentialing isn’t a one-time task. Payers typically require re-credentialing every 2–3 years, and licenses, malpractice insurance, and DEA registrations must be renewed regularly.

If any of these lapse—even by a day—providers may be terminated from networks, and claims could be denied retroactively.

How to Avoid It: Use a credentialing tracker or software system to monitor key dates, including:

  • State license renewals

  • Malpractice expiration

  • DEA certificate renewals

  • CAQH attestations

  • Payer re-credentialing deadlines

Set automated reminders at least 60–90 days in advance.

5. Underestimating the Volume of Work

Credentialing for one provider is time-consuming. Doing it for 5, 10, or 50 providers requires dedicated resources. Many practices try to stretch administrative staff too thin, leading to bottlenecks and costly mistakes.

How to Avoid It: Assign credentialing to a dedicated team member, or outsource it to a credentialing service with group practice experience. This frees up your staff to focus on clinical and operational tasks.

6. Not Following Up with Payers

Just because you submitted a credentialing application doesn’t mean it’s progressing. Payers often require additional documentation or clarification—but won’t always notify you promptly.

How to Avoid It: Build a follow-up schedule for every credentialing application. Check in with payers at key intervals (e.g., 15, 30, 45 days) and document all interactions. Proactive follow-up can reduce your credentialing time by weeks.

7. Lack of Credentialing Workflow or Standard Operating Procedures

Without a standardized credentialing process, every new provider brings confusion, delays, and inconsistency. This is especially problematic when onboarding multiple providers at once.

How to Avoid It: Develop clear credentialing SOPs, including:

  • Provider onboarding packet checklist

  • Credentialing and enrollment timelines

  • Communication templates for payer outreach

  • Centralized document storage procedures

Make sure every team member involved in the process is trained on these standards.

8. Not Leveraging Technology

Manual tracking through spreadsheets or paper files can quickly become unmanageable for group practices. Errors, duplicate files, and missed deadlines are inevitable.

How to Avoid It: Invest in credentialing software that supports:

  • Document storage

  • Expiration alerts

  • Status dashboards

  • Bulk provider management

  • Integration with CAQH and payer systems

Credentialing platforms reduce human error and increase visibility across your provider roster.

Pro Tip: Perform Regular Internal Credentialing Audits

Even if your team is experienced, credentialing processes can drift over time. Conduct quarterly audits to verify:

  • All active providers are enrolled with all major payers

  • No re-credentialing or license renewals are overdue

  • Data across systems (EHR, billing, CAQH) is consistent

  • Payer directories list your providers correctly

This helps catch issues before they affect reimbursement or compliance.
