Medicare's contractors must process 95.0% of clean electronic enrollment applications within 15 calendar days, according to First Coast Service Options, a Medicare Administrative Contractor for CMS. Yet only 65.0% of medical groups report their provider credentialing files are current and on time, according to an MGMA Stat poll of 131 practice leaders published in November 2025. The gap between the government's own clock and what practices experience is where independent practices lose billing time on every new hire.

A physician who cannot bill is a physician generating clinical work the practice cannot yet collect on. The figures below track how fast the credentialing system is designed to move, how far practices fall behind that design, and what the industry is spending in 2026 to close the difference.

What CMS Actually Requires

CMS sets separate timeliness standards depending on how a provider applies and whether a site visit is required. For an initial enrollment or change-of-information application filed through the internet-based PECOS system with no site visit, First Coast Service Options reports that CMS requires 95.0% of applications processed within 15 calendar days and 100.0% within 50 calendar days. Applications that need a site visit or fingerprinting move slower: 95.0% within 50 calendar days and 100.0% within 85 calendar days.

Paper applications run on a longer clock. CMS requires 95.0% of paper initial enrollments without a site visit processed within 30 calendar days, and 95.0% of paper applications with a site visit processed within 65 calendar days, per First Coast's published standards. Revalidation applications, the periodic re-enrollment every enrolled provider must complete, carry an 80.0% threshold at the same day counts instead of 95.0%.

Where Practice-Level Credentialing Falls Behind

MGMA's November 2025 poll found 65.0% of medical groups keep credentialing files on time. Of the rest, 23.0% report some type of backlog, 3.0% cite delays from their credentialing verification organization, 6.0% expect to catch up by the first quarter, and 3.0% gave other reasons. The poll drew 131 applicable responses from leaders managing new-hire credentialing, payer recredentialing, and reappointments.

Respondents who stayed on schedule pointed to a specific combination: enough staff, a written checklist, some automation, and turnaround targets held against their credentialing verification organizations. Groups with delays named payer enrollment slowness, slow reference and board verifications, thin staffing, and missing documentation as the recurring causes, MGMA found.

The Push to Fix Credentialing Technology

The gap between Medicare's own timeline and the slower commercial-payer and internal-review process is pushing hospitals toward new credentialing software. Black Book Research reported on June 5, 2025 that 42.0% of hospitals nationwide are budgeting for or actively planning to replace outdated credentialing platforms within 18 months. The firm tied the shift to new compliance deadlines: updated Joint Commission standards, requiring automated auditing and traceable peer review documentation, took effect in January 2026, and CMS is moving credentialing systems toward API and FHIR-compliant data exchange by late 2026.

Black Book also projected four to six acquisitions or mergers among credentialing technology vendors in early 2026, naming MedTrainer, Verisys, Andros Health, and symplr among the platforms already active in the market.

How Much Data Moves Through Shared Platforms

Much of the underlying credentialing data now flows through a small number of shared systems instead of payer-by-payer paperwork. DataSpring, the company formerly known as CAQH, reports more than 2.5 million providers have confirmed their information within the past 120 days on its provider data portal, and more than 1.8 million confirmed provider profiles sit in its directory management solution alone. Fifty-three health plans currently participate in that directory management program, and DataSpring reports one national health plan reached 84.0% directory accuracy after adopting the tool.

The separate CAQH Index, drawing on more than 600 provider organizations and health plans covering 63.0% of the country's insured lives, is the closest thing the industry has to a shared measurement of how much provider data exchange still runs through manual channels rather than a direct electronic feed.

What This Means for Independent Practices

Medicare's 15-day standard covers only one payer. A new physician still needs commercial payer credentialing on top of it, and MGMA's data shows 23.0% of practices already carry a backlog even with staff assigned to the task full time. The practices in MGMA's poll that stayed on schedule relied on a written checklist, adequate staffing, some automation, and enforced turnaround targets on their credentialing verification organization, the same four factors that separated on-time groups from backlogged ones.

The technology shift Black Book Research documented targets hospitals first, with 42.0% already budgeting for new platforms. CMS's own late-2026 API and FHIR requirement will eventually reach the credentialing vendors that independent practices and billing companies use as well, on the same compliance calendar now driving hospital purchasing decisions.
