Outsource Credentialing or Not: The Honest Sizing Guide

TL;DR: The outsource credentialing decision turns on load, not price. Operators report one payer application taking 30 to 40 minutes with everything in hand, and a full payer set running 10 to 16 hours per provider, spread across months of committee cadences and callbacks. Small, stable practices should usually keep it in-house. Multi-provider groups with turnover usually should not, provided the vendor answers the supervision problem.

Every administrator who has priced this decision has heard the same voice in their head: I could do this myself, faster, and know it was done right. That instinct deserves respect, because sometimes it is correct, and most content about whether to outsource credentialing is written by people selling it. The honest version starts with the hour counts nobody publishes, names the practices that should keep credentialing and contracting in-house, and prices the one cost both sides of the debate ignore: supervision.

A note on scope. Credentialing committee determinations, exclusion screening decisions, and payer network decisions remain the responsibility of the practice and the payer under federal and payer guidelines. A credentialing partner like HRG supports the surrounding workflow, meaning documentation, submission, tracking, payer follow-up, and file management. The practice retains authority over decisions that require its direct attestation and oversight.

The hour counts operators report, since nobody publishes a benchmark

Ask what credentialing costs in hours and you get a shrug, which is remarkable for a function that gates revenue. The nearest thing to a benchmark lives in operator threads, and the numbers are more useful than their spread suggests.

In AAPC's community, credentialers report a single payer application taking 30 to 40 minutes when every document is in hand, and a full payer set for one provider running far longer: one operator reports 14 payers taking about 10 hours, with others estimating 12 to 16 hours per provider across a typical commercial and government mix. For FQHCs, HRG's own reference benchmarks run higher still, 15 to 25 staff hours per provider for a fully manual process, against 2 to 5 hours of oversight when the workflow is supported.

The spread between 40 minutes and 16 hours is not sloppiness. The short number measures form-filling. The long number measures the job: gathering documents, chasing signatures, correcting a transposed NPI digit that would otherwise trigger a rejection, re-attesting DataSpring, waiting out committee calendars, and calling payers on their own schedules. The same operators are clear that accuracy beats speed, because one wrong digit costs more time than careful work ever takes.

The math that decides it, and the honest answer for small practices

Providers, times payers, times hours per payer set, times how often your roster changes. That product is the whole decision.

Run it with real numbers. A two-physician practice with a stable roster and twelve payers faces roughly 20 to 30 hours of credentialing work per recredentialing cycle, spread out over years. An administrator can absorb that between other duties, and the practice keeps full control. In that situation, keeping it in-house is the right call, and any vendor who tells you otherwise is selling. The forum consensus says exactly this, and it matches what we see: small offices with steady providers rarely need outside credentialing help.

The math flips with scale and motion. Ten providers across twenty payers is not five times the work of two providers, because turnover multiplies it: every departure and hire restarts the clock, and a group adding locations adds payer enrollments in batches. Somewhere in that growth, credentialing stops being a task and becomes a role, fragmented into fifteen-minute interruptions across every week. That fragmentation, not the raw hours, is what breaks in-house credentialing, because the work arrives on payer and committee schedules rather than yours. A 10-hour payer set consumes a quarter's worth of attention in slices too small to staff around.

The objection that decides more deals than price: supervision

The strongest argument against outsourcing does not come from vendors' competitors. It comes from operators who tried it. In the AAPC thread asking who outsources their credentialing, a practice manager at a large organization reports that managing the vendor took so much correspondence that the time saving evaporated: I could have just done it myself, and much quicker. Another describes switching vendors and waiting roughly six months while payers loaded the updated group TID, with claims denying as out of network the whole time.

Take that objection at face value and it defines what a credentialing vendor has to prove: that supervision is priced, visible, and capped. A vendor you have to chase is a second job. A vendor whose work you cannot see is a liability with a contract.

In-house, typical vendor, or HRG: the comparison that matters

The supervision row is the one to interrogate with any vendor, including us. What matters is the mechanism rather than the promise: a client-set hours budget converts supervision anxiety into a number you control, and invoices reviewed before charging mean the correspondence happens before the money moves, not after.

What outsourcing has to include before it is worth paying for

Anything less than this list is form-filling with a markup, and form-filling is the part your team can already do.

• Tracking through to the first clean paid claim, because the expensive failures happen after approval, when group linkage and payer loading lag the letter.
• DataSpring maintenance on a fixed cycle, not on reminder emails. HRG maintains profiles every 30 days, and since moving to 30-day maintenance has seen roughly 90 percent fewer A/R issues from outdated provider data, a Mellissa-confirmed track record.
• Payer sequencing, with the slowest payers started first, so your revenue-ready date is set deliberately rather than discovered.
• Recredentialing dates tracked as deadlines with lead time, because a lapse interrupts revenue that already exists.
• A transition plan measured in specifics when you switch, since operators report group TID loading alone taking months. Any vendor who cannot describe the transition window is planning to surprise you with it.

If a proposal cannot show you how each of these works, the hour counts above tell you what you would be paying for, and it is not much.

How HRG structures the engagement

HRG has run credentialing for over 26 years, and the model is built around the two findings that decide this: the work is fragmented, and the buyer's deepest fear is supervision. Credentialing is billed hourly, for time used. You set a monthly hours budget, we flag when the work approaches it, and you decide whether to add hours or defer. Invoices come to you for review before charging. The contract is one page, month to month, with no minimums, so the engagement survives on results rather than on lock-in. Behind it sits a 100 percent approval record on the hospital privilege applications we have managed, phrased carefully: a track record, not a guarantee, because final decisions rest with payers, hospitals, and your own committee.

And if the sizing math says keep it in-house, keep it in-house. The practices that outsource credentialing well are the ones that did the math first, which is why our guide to choosing a medical credentialing service starts with fit rather than features, and why provider credentialing done as revenue work reads differently from credentialing done as paperwork.

Ready to run your numbers

Count your providers, your payers, and your roster changes over the last two years, then put an honest hour figure against each. If the product looks like a role rather than a task, schedule a call with Mellissa and bring the numbers. Should the math say in-house, we will say so. Or call 913-937-2995.

Outsource credentialing questions, answered straight

How many hours does credentialing take after the initial enrollment is done?

The work never fully stops: DataSpring attestations come due every 120 days, licenses and DEA registrations expire on their own calendars, and commercial recredentialing returns every few years per payer. HRG runs that maintenance on a 30-day profile cycle so the recurring hours stay predictable instead of arriving as emergencies.

At what size does outsourcing credentialing make sense?

The forum consensus and our own experience agree: small practices with stable rosters should keep it in-house, and the case for outsourcing builds with provider count, payer count, locations, and turnover. HRG will run the sizing math with you before proposing anything, because a client who should not have outsourced becomes a former client quickly.

Is outsourced credentialing worth it if we still have to manage the vendor?

That objection is the best filter you have, and most vendors fail it. HRG answers it structurally: a monthly hours budget you set, a warning flag as it approaches, and invoices reviewed by you before charging, so supervision is a number rather than a correspondence pile.

What does switching credentialing vendors cost in downtime?

Operators report the painful version: roughly six months for payers to load an updated group TID, with claims denying as out of network throughout. HRG names the transition window and its dependencies up front, because a switch you can schedule around is an inconvenience and a switch you discover in denials is a crisis.

Can we outsource credentialing but keep contracting in-house?

Yes, the two engage independently. Many practices hand HRG the credentialing workflow and keep payer negotiations, and some do the reverse, since HRG also negotiates directly with payers with final terms resting with the payer and the client. The one-page month-to-month contract makes the split easy to adjust.

What should we ask a credentialing vendor before signing?

Ask how they track to the first clean paid claim, what their DataSpring maintenance cycle is, how they sequence payers, what the transition window looks like in weeks, and how supervision is capped. HRG publishes its answers, meaning 30-day maintenance, slowest-payer-first sequencing, an hours budget with a warning flag, and invoices reviewed before charging.

The decision, sized

Credentialing rewards honesty about scale. Under a certain load it is a task your team should own, and past that load it is a role that fragments across everyone and belongs with people who do nothing else. Run the numbers before anyone runs a pitch, and if they say outsource credentialing, hold the vendor to a supervision standard with a cap, a flag, and an invoice you see first.
