In-House Biller, Billing Company or Managed RCM? How to Choose When Your Biller Leaves

November 11, 2026

Athelas gives you two ways to answer this question. Athelas Air is an AI-native EHR and practice management suite with billing built in. Your own biller runs claims, posting, denials and statements in the same system as the schedule and the chart. Athelas RCM is a managed billing service: our team and software do the billing work for you. That includes claims, coverage checks, payment posting, denials, follow-up on unpaid claims and patient statements. You can add it onto Athelas Air or use it with the EHR you already have. Both run on the same Athelas billing platform.

When a biller gives notice, the real risk is not the empty seat. It is what leaves with them: payer history, open accounts receivable (AR) and the habit of chasing claims. In 44% of the practices we analyzed on recorded revenue-cycle calls, the practice described battles with payers: claims stuck, underpayments and aging AR. In 37%, the practice described building reports by hand, with no view of visits, collections or productivity. These are call observations from practices that spoke with us, not a representative survey.

Key takeaways

Start with ownership. Decide which billing work you want to run yourself before you compare vendors.
Handoffs lose money. Credentialing grids, NPI status and claim status are where work stalls.
Ask about old AR. Settle who works it while new claims keep moving.
Compare quotes line by line. Billing only, denials, statements and reports can be priced differently.
Pick the setup, not just the person. Keep billing in-house on Athelas Air, so payer rules live in the system instead of one biller's head. Or hand the work to Athelas RCM, on Air or on your current EHR.

How do we choose between an in-house biller, a billing company and a managed RCM service?

It depends on how much billing work you want to own.

You want your own biller, with less riding on one person: Athelas Air. Your biller works the whole revenue cycle in one EHR and practice management system. Rules, credentialing status and claim status live in the software, so a new hire inherits them. If you want to keep your EHR, Athelas practice management can run billing alongside it.
You want someone else to do the work: Athelas RCM or a billing company. Athelas RCM's billing team and software scrub and submit claims, check eligibility, post payments, work denials and send patient statements. It works with your current EHR, or you can add it onto Athelas Air.
Your team is strong and only needs a claims tool: a software-only vendor can fit.

Under every option, you keep credentialing, contracting and prior authorizations. Compare the options in the table below.

Which branch fits you? A decision tree

Work through these questions in order. The first "yes" usually points to your model.

Do you want to supervise billing staff day to day? If yes, keep billing in-house and hire a replacement. The tradeoff is that your results depend on one person's knowledge again. To reduce that risk, give the new biller a system that holds the knowledge. In Athelas Air, payer rules are written in plain English, every rule change is kept with a one-click rollback, and provider credentialing status sits in one place.
Is your team strong, and do you only need a claims tool? If yes, a software-only vendor can fit. The tradeoff is that your staff still work every denial and payer call.
Do you want a company to do the work but keep your own systems? A billing company or managed RCM service fits. Ask who is named on your account and who owns appeals.
Do you want the billing team to work inside your current EHR setup, with dashboards you can open yourself? Managed RCM with a software layer fits. Athelas RCM works alongside your EHR, so you do not have to switch.
Are you also unhappy with your EHR? Compare an integrated platform. Athelas Air is the EHR and practice management system. Your own biller can run billing in it, or Athelas RCM can be the billing service on top of it.

How do you replace a departing or retiring biller without losing collections or billing knowledge?

Bring in coverage before the last day, and move knowledge out of one person's head. Three things tend to break during a handoff.

Claim status. In one customer call, a rehab owner had heard nothing for about two weeks on whether claims were going out, and was worried about cash.
Credentialing and NPIs. One practice sent a credentialing grid by spreadsheet and had not heard back. A new therapist had no NPI yet, so the therapist was not on the roster.
Payer enrollment. A podiatry practice's billing side showed a provider's Medicare credentialing as complete, but the payer had given no timeline, and that provider's claims stayed held.

Before the biller leaves, ask them to document payer quirks, open appeals and enrollment status. Then ask any vendor who tracks enrollment and who chases the payer. In the Athelas billing platform (used by Athelas Air and Athelas RCM), much of that knowledge has a home:

Payer quirks become rules. Describe a rule in plain language and get a working draft. New rules stay inactive until someone turns them on, and every version is kept.
Enrollment has one place. Payer enrollment and credentialing status is tracked per provider. Athelas handles EDI and ERA enrollments with every payer at onboarding.
Claim status is visible. Each claim shows its status, stage and owner on the same row, and claims can be assigned so each biller works their own list.

What does each model cover?

The table below shows who does each task. Credentialing, contracting and prior authorizations stay with you in every model.

Task	In-house biller on your current systems	Software only	Athelas Air (your biller)	Athelas RCM (on Air or your EHR)
Eligibility checks	Your staff	Your staff	Automatic before each appointment; your staff call payers the clearinghouse can't reach	Athelas checks eligibility before visits
Claim scrubbing and submission	Your staff	Tool assists	Rules engine scrubs and submits; your biller fixes what the rules can't	Athelas scrubs and submits through the clearinghouse
Payment posting	Your staff	Your staff	Balanced remittances post automatically; your biller works the exceptions	Athelas posts payments and reconciles deposits
Denials and appeals	Your staff	Your staff	Your biller, with denials grouped by reason and payer for bulk resubmission	Athelas works denials and appeals
Aging AR follow-up	Your staff	Your staff	Your biller	Athelas follows up with payers on unpaid claims
Patient statements	Your staff	Tool assists	Recurring statements on your cadence, by text, email or mail	Athelas sends statements by text, email or paper
Credentialing, contracting, prior authorizations	You	You	You	You

A few specifics from the product documentation:

Claims. Each claim runs through a billing rules engine before it goes to the payer through the clearinghouse. Rejections, denials and remittances surface back on the claim.
Eligibility. Checks return results such as Active, Inactive or Inconclusive, with recommendations for copay, deductible and coinsurance.
Statements. You set frequency, balance thresholds and delivery by text, email or both. Paper goes to patients who opted out of digital delivery.
On Athelas Air, billing and the chart live in one system, so a signed note becomes a billable charge with nothing to sync.

One customer on Athelas RCM, a rehab biller, reported that Athelas AI resubmitted 18 claims in under 5 minutes. That is customer-reported on a call, not audited.

Payer follow-up deserves its own question. A chiropractic practice described med-pay claims unpaid for about six months, with no direct contact at the payer. Ask each option how long a stalled claim sits before someone calls.

Mixed setups can cost more. A behavioral health customer who split billing between Athelas and employed staff said the combined cost was too high. If you keep a biller and buy a service, define who does what. If you want your biller to own the work, Athelas Air gives that biller the same billing platform without splitting the work with a service.

How do owners keep visibility and own their reports?

You should be able to open claim status, AR and collections without asking anyone. Reporting fails owners whether billing is in-house or outsourced. One orthopedics leader described about 3 hours of digging before answering leadership's collections questions. A pain management CFO went two months without reliable denial and adjustment data from a billing company.

Athelas Air and Athelas RCM give you the same dashboards and reports:

KPI dashboards. First-pass rate, collection rate, days to paid and denial rate on one screen, each compared with the prior period. Every number opens to the claims behind it.
Denials Analysis. Shows denial metrics and revenue recovered through resubmission, so you can see how your practice and Athelas are working together.
Aging AR Report. Shows balances in buckets from 0 to 30 days up to 366+ days, grouped by claim type, provider, facility, billed insurance or EHR insurance.
Collections reports. Include a custom collections report and a posting log.

Customer-reported on calls: a revenue team said Athelas reports replaced manual report building within a couple of months. An accountant finally accepted a revenue report after about three years of mismatched numbers. Neither is audited.

The documentation does not state data ownership or export terms. Ask any vendor in writing what you can pull yourself, including facility-level collections.

How do you take over aging AR while current claims keep moving?

Plan on two tracks. Older AR is usually worked down in the previous system while new claims run on Athelas. A rehab owner who inherited a large backlog of old receivables from a prior billing vendor wanted that backlog worked, so ask each vendor whether it will chase legacy AR and on what terms.

If you are also moving your EHR to Athelas Air, billing keeps running throughout the migration, so collections do not pause for the cutover. Migrations can be done in 30 to 60 days based on your practice's complexity.

One rehab customer on Athelas RCM reported AR cut in half in the last month, about 12,000 reduced from the backlog. This is one customer's account from a call, not audited, and not a promise.

How are Athelas Air and Athelas RCM priced, and what should a like-for-like quote include?

Athelas Air is priced per provider, with EHR, practice management, billing software, Ambient AI, Athelas Assistant, clearinghouse and portal in one price. Front desk staff and billers are not charged as users.
Athelas RCM is a separate managed service, priced as a percentage of collections with a monthly minimum. Rates are not published. A free financial health analysis sizes what your practice could recover.

Book a demo for pricing scoped to your provider count, specialty and current setup.

In our conversations, price complaints are rare: 1% of analyzed practices on recorded revenue-cycle calls said managed billing seemed too high for the value. The more common ask is transparency. Prospects want the full fee structure and a cost breakdown per option, and some want everything bundled into one percentage.

Ask every vendor the same questions:

Scope. Does the price cover claims, denials, appeals, statements and reporting?
Fees. Are there separate charges for statements, reports, appeals, the clearinghouse or extra users?
Minimums. What is the monthly minimum, and when does it apply?
Old AR. Is legacy AR included or priced separately?
EHR. Is the EHR in the quote, or do you keep yours?
Your own costs. Include salary, benefits, clearinghouse fees and software you would keep.

Frequently asked questions

What is the difference between Athelas Air and Athelas RCM?

Athelas Air is an AI-native EHR and practice management suite with billing built in, so your own biller runs the revenue cycle in the same system as the schedule and the chart. Athelas RCM is a managed billing service: our team does the billing work for you. You can add Athelas RCM onto Athelas Air or use it with your current EHR.

Should we replace a departing biller or hire an RCM company?

Hire an in-house replacement if you want to supervise billing yourself. Putting that biller on Athelas Air keeps payer rules, enrollment status and claim status in the system rather than in one person's head. Choose Athelas RCM if you want a managed team working alongside your current EHR or Athelas Air, so one person's departure does not stall claims. Either way, document payer history, open appeals and enrollment status before the last day.

Do we have to switch EHRs?

Not for Athelas RCM. It works alongside your existing EHR, and how deep the integration goes varies by EHR, so ask about yours. Athelas Air replaces your EHR and practice management system. Migrations can be done in 30 to 60 days based on your practice's complexity; book time with our team to plan yours.

What work does the practice still do under managed RCM?

You keep credentialing, payer contracting and prior authorizations. You also provide a daily point of contact for questions from the billing team. Athelas handles eligibility, claims, posting, denials, payer follow-up and statements.

How are Athelas Air and Athelas RCM priced?

Athelas Air is one per-provider price for the platform, including EHR, practice management, billing software, Ambient AI, Athelas Assistant and clearinghouse. Athelas RCM is a separate service, priced as a percentage of collections with a monthly minimum; rates are not published. Book a demo for pricing scoped to your practice.

Can we see billing performance without asking the billing team?

Yes, with Athelas Air or Athelas RCM. Dashboards and reports show claim status, AR and collections, including a Denials Analysis page and an Aging AR report grouped by provider or facility.

What happens to old AR when we switch?

Older AR is usually worked down in the previous system while new claims run on Athelas. If you also move to Athelas Air, billing keeps running through the migration. Ask any vendor in advance whether it will work legacy AR and how.
