What “credentialed” means and why nothing pays before the effective date.

Owners say “credentialed” when they mean “we can bill now.” Payers use the word for one step inside a longer file. A practice can lose its first claims in the space between those two meanings.

Three approvals that sound like one.

Credentialing is the payer checking a provider's licenses and qualifications. Payer enrollment is the payer registering that provider, or the practice itself, so claims can be paid in-network. The effective date is the day the payer starts paying those claims.

All of it happens once per payer. A separate application goes to each payer for each provider.^A Approval from one commercial plan tells you nothing about the next one. A provider can be fully enrolled with Medicare and still be out-of-network with every commercial plan nearby, because Medicare enrolls through PECOS, its own system, separate from the CAQH profile the commercial plans read.

The practice has a file too.

A payer enrolls more than people. The practice itself can need its own application with each payer, apart from the provider's, and a provider joining an existing group has to be tied to that group in the payer's records. That is why we price the two separately: $350 for an organization application and $250 for each practitioner application. For a solo practice we file and charge one application per payer, at $350.

Where a payer allows it, one contract covering every provider in the practice gives the practice more weight with that payer than a string of individual contracts.^A Whether that door is open depends on the payer, and we ask before we file.

The date that matters.

The effective date is the date a payer starts paying a provider's claims. A claim for a visit before that date has no guarantee of payment. A phone call saying the file looks fine is not an effective date. Until the payer puts the date in writing, we treat it as unset, and the Friday board says so.

Owners often ask whether a payer will reach back and cover visits seen while the file was still open. That is each payer's decision, made in its own letter. We do not plan a practice's cash around it, and we would not ask you to.

Why the gap stays hidden.

A missing enrollment rarely announces itself. The provider believes they are in network, the front desk books the patient, the claim goes out, and the first sign of a problem is the denial.^C

In an MGMA Stat poll, 54% of medical groups said credentialing-related denials were rising.^B It was a single-question poll of 425 groups, and not a recent one, so read it as a direction rather than a measurement. Each of those denials says the same thing in payer language. On the date of service, this provider was not enrolled with this payer.

Waiting without turning patients away.

Timing is the part nobody controls. Commercial payers take months, Medicare is usually faster, and Medicaid varies by state.^A Two arrangements can help while the files are open. Neither one replaces enrollment.

A single-case agreement can cover one patient while a provider's credentialing is pending. The payer decides whether to grant it, usually when its network cannot serve that patient or when care is already under way. It covers that one patient's care. It does not put the provider on the panel.^D

Medicare's incident-to rule lets some visits by a provider who is not yet enrolled be billed under a supervising physician who is. The physician has to supervise on site, and the patient's plan of care has to be established already. Commercial payers set their own limits on it.^E Outside those conditions the rule does not apply, and we would not use it.

What to ask whoever is doing this work.

Whether enrollment sits with your office manager, a vendor or us, a few questions show where the practice stands. Which payers have an application in, and for which providers? Which of them has set an effective date, and where is it written down? Who follows up with a payer that has gone quiet, and on what day?

Our answer is the Friday board. It lists each payer, its status, the next action and the effective date once a payer commits to one. When the work is done, the enrollment file stays with the practice. None of that makes a slow payer faster. It does mean you always know which payer is the slow one. If we also run your billing, the claims go out under each date as it lands, and we follow every one until it is paid.
