CMS 855I, 855B and 855R Explained: Medicare Enrollment Forms for Practices
Medicare enrollment has its own alphabet: the 855I for the individual, the 855B for the group, the 855R to connect them, and PECOS to hold it all. We explain which form does what, the order to file them, what triggers a rejection, and the maintenance rules that keep a practice from being deactivated.
A 2026 Credentialing Calendar: Revalidations, Re-Attestations and Renewals
Credentialing work that is missed does not announce itself until a claim denies or a payer terminates the provider. Here is the calendar we keep for every provider: the 120-day CAQH cycle, Medicare revalidation, payer recredentialing, licenses, DEA, CLIA and the 30-day NPPES rule.
Credentialing vs Contracting vs Enrollment: The Three Steps Practices Confuse
A new physician is not paid until three separate processes finish: credentialing verifies the person, contracting sets the terms, and enrollment loads the provider into the payer system. Here is what each step does, who runs it, how long each takes and where the handoffs fail.
Credentialing Before January: Network Checks, CAQH, Revalidation and New Plans
January brings new plans, terminated plans, new providers and payer contract changes at the same time. Here is the credentialing checklist we run in the last days of the year and the first days of January so that no provider is out of network or out of revalidation when the January claims go out.
Credentialing Timelines for Fall Hires: Counting Backward From the Start Date
A provider starting October 1 whose file opened in late August will not be enrolled with most commercial payers until winter. Here is the calendar math for fall hires, what can still be rescued, how to schedule around pending payers, and the billing rules that are not shortcuts.
Credentialing With Medicare Advantage Plans: What Differs From Original Medicare
A provider enrolled in PECOS can bill Medicare on day one and still be out of network with every Medicare Advantage plan in town. Here is how MA credentialing actually works, why the timelines differ, how the preclusion list fits in, and the sequence that gets a new provider paid by MA plans without a gap.
Credentialing a Provider Who Starts in Q1: A Plan When You Are Already Late
A physician starts April 1 and the enrollment file was opened last week. It happens every winter. Here is how we triage the payer list, what Medicare allows retroactively, how to schedule around pending plans, and the claim-holding discipline that keeps timely filing intact.
Credentialing Renewals, CAQH Attestations and Revalidations in December
Licenses, DEA registrations, CAQH attestations, Medicare revalidations and payer recredentialing all expire on their own calendars, and several cluster at year-end. Here is the December review we run, the intervals for each item, and the failures that stop payment for a whole provider without warning.
Credentialing a New Practice Location: What Payers Need and How Long It Takes
Opening a second office looks like a real estate problem until the first claims from the new address deny. Here is what each payer type requires when a group adds a location, the order to do it in, the forms involved, a dated example, and the claim holds that keep new-location claims from becoming write-offs.
