Gastroenterology Billing Services: 7 Companies Compared by Fees, Software and Scope

A gastroenterology billing service does the work of getting your GI practice paid. It codes your visits and procedures, sends the claims, posts the payments, chases denials and bills patients. A quote may charge a percentage of collections or a flat amount.

We read seven companies' relevant GI and billing pages. AdvancedMD lists a typical 4–8% of practice collections for its general managed-billing service, with its practice-management and EHR software included. That is not a GI-specific quote. CureMD illustrates a 5% fee in a GI return-on-investment example, but does not present it as a firm rate. Get a written proposal for your practice.

So you can't choose on price alone. Check three things before you sign:

1. Does the company cover every bill your practice sends?
2. Can you keep your current software?
3. What does the quote cost after minimums and extras?

The table below shows what each company says. The Quote Check turns percentage or flat-fee quotes into monthly and first-year dollar figures, and flags missing terms.

Compare 7 gastroenterology billing companies

Companies are listed A to Z. This is not a ranking. Everything in the table comes from each company's own website.

"Not posted" and "not stated" mean we did not find it on the pages we read. It is a question to ask. It does not mean the company can't offer it.

We did not establish a complete set of minimums, contract lengths and exit fees from the pages reviewed. AdvancedMD advertises no long-term agreements. Ask all seven for the actual terms in writing.

Where to start

These are starting points based on what each company publishes. They are our reading, not test results.

• You use ModMed's gGastro. Start with ModMed. Its billing service runs on ModMed software.
• You want billing and software from one company, with a price range you can see. Start with AdvancedMD.
• You already use AdvancedMD, or you're open to it. Compare AdvancedMD's own service with Practolytics, which is an AdvancedMD partner.
• You own your endoscopy center, or you bill anesthesia or pathology. Ask CureMD about its stated anesthesia, pathology and surgery-center scope. Ask MedCare MSO about its stated facility/physician claim coordination. Get each billing entity named in the proposal.
• You want to keep the system you have. BSI, CureMD, MedCare MSO, PGM Billing and Practolytics describe outside-system connections. Get your exact system and the work the interface handles named in the proposal.
• You're solo or small. MedCare MSO and Practolytics both say they take solo practices. Ask about the monthly minimum first. It matters most when collections are low.

Ask Practolytics for a quote

Before you write to anyone, grab the proposal request further down. It makes every company answer the same questions.

Treat the big numbers with care

Some of these pages show impressive results. MedCare MSO shows a 96% collection ratio and a 98.5% first-pass clean claims rate. Practolytics says it has served 1,400+ GI practices. CureMD's page title promises "35%+ ROI."

These are the companies' own numbers, not comparable test results. Before using a number to choose a company, ask what time period and group of practices it covers, and how it was counted. Then ask for two GI practices you can call.

One more thing to know: Practolytics' contact form includes consent to recurring text messages, and MedCare MSO's form also includes SMS consent. Read the contact choices before submitting.

What a GI billing service has to cover

"GI billing" can cover several billing streams. What you need depends on which entities send the claims and which work your practice controls.

Take one colonoscopy. Depending on the setting and services, there may be separate charges for the doctor's work, the facility, anesthesia and pathology. Some services are included in another payment, and some charges come from separate businesses. Medicare distinguishes surgery-center facility services from physician and anesthesia services. Ask which claims your proposal covers.

Use this table to mark what's yours.

If the hospital bills its own facility fee, that claim isn't yours to hand off.

Then mark the daily work. For each task, the proposal should say included, costs extra, or stays with your staff.

• Checking insurance eligibility
• Prior authorizations, including renewals
• Coding
• Entering charges and sending claims
• Posting payments
• Working denials and appeals
• Patient statements and patient phone calls
• Credentialing and payer enrollment
• Collecting old unpaid claims

A company can have software that supports facility billing and still not do your facility billing. Those are two different promises. Get the one you need in writing.

What do gastroenterology billing services cost?

AdvancedMD publishes a typical 4–8% of practice collections for its general managed-billing service, with practice-management and EHR software included. Implementation and optional features can add fees. CureMD's GI ROI illustration uses 5%; it is not a firm GI quote. Ask each company for your rate, fee basis and complete charges.

You'll see other ranges online. One billing company's blog says GI billing runs 4–8% of net collections. Another says 3–10% of monthly collections. Both are sellers describing their own market. Neither documents how its market-wide range was measured. We don't treat either as an average.

The percentage is only half the price

The other half is what the percentage is of. Some companies charge on every dollar the practice collects. Others charge only on insurance payments. The same practice gets two very different bills.

Here is a made-up example. These are not prices from the companies above. A practice collects $180,000 a month. Of that, $150,000 comes from insurers and $30,000 from patients.

Quote B has the higher percentage and costs $350 less each month. Even with its $3,000 setup fee, it costs $1,200 less over the first year.

That is a fee comparison only. It assumes the same work and practice collections, with all required charges included. First-year costs repeat that same month for 12 months, then add the one-time setup fee.

Watch the monthly minimum

A monthly minimum can put a floor under the percentage fee. In the examples and tool here, you pay the higher of that minimum or the percentage fee, then add other monthly charges. Check that your proposal uses the same rule.

Say a quote is 5% with a $2,500 minimum, applies to all collections, and has no extras. You collect $40,000 in a slow month. Five percent would be $2,000. The minimum is higher, so you pay $2,500. That is 6.25% of what you collected. At $50,000 in fee-eligible collections, the percentage fee equals the minimum; above that, the percentage controls.

Check this at a new or solo practice's expected collection volume, including a slow month.

If you give infusions, ask about drug payments

Infusion drug payments also have to cover buying the drug; they are not pure profit. A percentage charged on drug payments can cost a lot.

Another made-up example. A practice collects $300,000 a month, and $150,000 of it is drug payments.

• 4% on everything, drugs included: $12,000 a month.
• 5.5% on the $150,000 that isn't drugs, plus a flat $1,000 for infusion billing and $500 for software: $9,750 a month.

The second quote has the higher rate and costs $2,250 less each month, assuming the same work and no other charges. Ask every company whether drug payments count toward its fee and, if excluded, how infusion work is priced.

Check your own quotes

Type in the terms from two written quotes. The tool shows the monthly cost, the real rate and the first-year cost for each. The calculation runs in your browser. Press "Load the worked example" to see Quote A and Quote B from the table above.

Leave a box blank if you don't know the answer yet. The tool treats a blank as unknown, not zero. It will tell you what to go back and ask.

Use the same month's practice collections for both quotes. Only mark the scope as the same after checking every billing stream and task. Annual figures assume the same month repeats for 12 months, with unchanged collections and fees; they are not a revenue forecast. The tool supports a percentage fee with a minimum, or a flat monthly fee, plus extras. A tiered, per-claim or per-provider quote needs to be reduced to an agreed monthly amount for that volume before you can use the flat-fee option.

Want to see how a real company's minimum plays out? Our homepage cost example uses Recoup's published mental-health billing terms. It illustrates the minimum calculation, not GI pricing.

5 questions that show whether a company knows GI

Anyone can put "colonoscopy" on a web page. Ask each company how it would bill these five cases. These Original Medicare examples let you check its answers against public rules.

Use them to compare companies. The actual procedure record and current payer rules control how a real claim is coded and processed.

If a company fumbles these, ask for its coding lead before you go further.

Private insurance has its own rules. Some plans require modifier 33 and specific diagnosis coding when a preventive screening becomes diagnostic or therapeutic. For example, Point32Health's instructions effective October 1, 2026 apply to Harvard Pilgrim Health Care Commercial and Tufts Health Direct. Missing or incorrect information can affect how the claim is processed. Ask how the company checks each plan's current instructions.

If you give infusions, ask the company to walk you through one drug, from prior authorization to a paid claim. Ask who tracks renewals.

Two dates to ask about

• January 1, 2027. The applicable Original Medicare coinsurance when a screening colonoscopy includes tissue removal drops from 15% to 10%. It goes to zero in 2030 (CMS coinsurance schedule). Ask who updates your patient estimates and statements.
• 2026 Medicare rates. CMS applied a −2.5% efficiency adjustment to work relative value units and the corresponding intraservice physician time for applicable non-time-based services. Evaluation and management services are among the exemptions. This is not a flat 2.5% cut to every payment: other rate-setting changes also matter. Ask each company to check the current allowed amounts for your most common procedure codes.

Use these questions in my proposal request

Can you keep your current software?

Decide this before you compare prices. Moving systems can add cost and staff work.

• ModMed's billing service runs on ModMed's practice-management system. It fits best if you're on ModMed or ready to move.
• AdvancedMD includes its practice-management and EHR software in the fee. Implementation and optional features can add fees. Ask if you can keep a different EHR and which system your claims would use.
• BSI says its billing software can interface with multiple systems. Confirm your exact EHR and who maintains the connection.
• Practolytics is an AdvancedMD partner and says it works with other systems too. Ask which system your claims would live in.
• CureMD and MedCare MSO each have their own software and say they connect with yours. Ask how, and what data moves.
• PGM Billing says it connects outside EHRs to its own billing platform. Confirm the interface, data flow and fees for your system.

Three questions for every company:

1. Which system will my claims live in?
2. Can I log in and see my own claims any time?
3. If I leave, how do I get my data, in what format, and what does it cost?

What to get in writing before you sign

The public pages do not provide complete contract terms. Get each of these in your proposal and agreement.

Money

1. The rate, and exactly which payments it applies to.
2. The monthly minimum.
3. Setup, software, statement and card-processing charges.
4. The fee for collecting your old unpaid claims. This may be priced apart from day-to-day billing.

Work

5. Which bills are covered: physician, facility, anesthesia, pathology, infusion.
6. Who handles prior authorizations and patient phone calls.
7. Who works denials, and how fast.

Reports

8. A sample monthly report. Ask how each number is counted. "Denial rate" can mean a share of claims or a share of dollars, and the two can look very different.

Leaving

9. Contract length and how it renews.
10. Notice needed to cancel, and any exit fee.
11. Who finishes your open claims after you leave, and at what fee.
12. How you get your data back.

Privacy. An outside billing company that handles protected health information on behalf of a HIPAA-covered practice is a business associate. Have a written business associate agreement in place before giving it that information or access. "HIPAA compliant" on a website is the company's own claim. Ask about safeguards, incident reporting, subcontractors and where the work is done.

Switching without losing claims

1. List what's open. Unpaid claims, pending authorizations, payments not yet posted.
2. Take a dated snapshot of everything unpaid. Agree in writing who works the old claims.
3. Test before go-live. Ask the new company to run sample claim workflows end to end in a test environment.
4. Pick a cutover date. Agree who works claims on each side of that date, including late charges and payments on older claims. Reconcile the handoff so claims aren't missed or sent twice.
5. Meet weekly at first. Review what's stuck and who owns it.

A public onboarding estimate isn't your practice's schedule. Practolytics says most GI practices switch within weeks. Ask for a plan with dates.

If you're replacing a billing company, read your current contract first. Look for the notice period and what happens to open claims.

Gastroenterology billing services: common questions

Which gastroenterology billing company is best?

There isn't one best company for everyone. A solo doctor who only needs physician billing has different needs than a group with its own endoscopy center. Start with the two or three companies whose software and scope match yours. Then compare their written answers.

Do I need a company that only does GI?

No. These companies serve other specialties too. What matters is proof: GI practices you can call, and right answers to the five questions.

Will a new company collect my old unpaid claims?

Maybe, and it may cost a separate fee. MedCare MSO and Practolytics both list recovery of old balances as a service. Neither says on its GI page whether it's part of the regular percentage. Ask for the fee and how far back they'll go.

We have a good billing team. Do we need a service at all?

Maybe not. If your team is doing the work well, better software or a coding audit may be enough. A service makes sense when you can't staff the work or can't see where the money is going. Use the Quote Check's flat-fee option for your monthly in-house cost (pay, benefits, software and training), counting each cost once, before you decide.

I'm a patient with a question about a colonoscopy bill. Can you help?

We can't look at your account. Call the number on your bill and ask which provider sent each charge. Then check the explanation of benefits from your insurer. If you have Original Medicare, the Medicare colonoscopy page explains its coverage and cost-sharing rules.

Does MedicalBillingSelect do the billing?

No. We compare what billing companies publish. The company you choose does the work, and you contact it directly.

How we checked

We read each company's relevant GI and billing pages, including AdvancedMD's GI software, managed-billing and pricing pages, on October 5, 2026. We chose companies that publish relevant GI information and say enough to compare. We left out companies whose pages we could not read in full. A company that isn't listed is not a bad company.

We did not request quotes, test any billing company's service or measure its results. Company claims are labeled as the company's own. Medicare rules link to CMS, Medicare.gov or a Medicare contractor; the private-insurance example links to the payer. The dollar examples are made up and labeled that way. We recalculated them and tested the supplied Quote Check separately.

Companies do not have to pay to be considered for an editorial comparison. If a price or term has changed, tell us and send a link to the source. Read how we compare companies.
