Marathon

Dental insurance billing

Get your dentalclaims to thefinish line.

Marathon runs every claim the whole distance. When a visit ends it builds the claim, attaches the X-rays, perio chart and narrative, and checks it. After your team presses send, it follows the claim through the clearinghouse and the payer and updates it at every step, until it is paid.

$1,000 per location a month. Nothing charged today. Billed at the end of each month. Cancel anytime; service runs to the end of that month.

Ready when the visit ends. Evidence already attached.

No re-keying and no hunting through the imaging system. Each claim arrives with the X-ray, perio chart and narrative the payer asks for, and it is never marked ready while anything is missing.

Procedure
D4910 Periodontal maintenance

Patient presents for periodontal maintenance following scaling and root planing (D4341) in all four quadrants. Today's charting shows Stage II, Grade B periodontitis, now stable, with probing depths of 2 to 4 mm and a residual 5 mm pocket on tooth #2 with bleeding on probing. The panoramic image shows horizontal bone loss consistent with the prior diagnosis. Periodontal maintenance at a three month interval is needed to keep the results stable and prevent recurrence. Perio chart and panoramic image attached.

Tracked the whole distance

Caught before the payer sees it. Followed until it is paid.

Every claim is checked before it goes out, and anything unclear waits for your team with a plain explanation. After it is sent, Marathon watches every clearinghouse and payer response and updates the claim at each step, so your team always knows where it stands. If a payer rejects it, you see why in plain words, fix it and send it again.

Questions

Questions offices ask

Something else? Write to contact@marathonclaims.com or book a call.

What does Marathon do?

Marathon is dental insurance billing software that builds each claim from your practice software, attaches X-rays, perio charts and narratives, checks it before it is sent, and follows it at every step until it is paid. Your team reviews and sends.

How much does Marathon cost?

$1,000 per location per month for the software, with unlimited claims. Groups with 5 or more locations get volume pricing, and full service, where our team runs your billing, is priced to your office. Talk to us for either.

When is my card charged?

At the end of each month, for that month. Your card is saved when you sign up and nothing is charged that day. There is no contract. You can cancel anytime, and service runs to the end of that month.

Which practice software does Marathon work with?

Marathon connects to your practice management software, including OpenDental and Dentrix, and we keep adding systems. Using something else? Talk to us about yours.

Can my team review claims before they are sent?

Yes. Ready claims are grouped so your team can send them together, and claims that need attention say exactly what is missing. Nothing is sent until someone on your team presses send.

What does Marathon track after a claim is sent?

Every step to the finish line. Marathon records when the clearinghouse receives the claim, when the payer accepts or rejects it, and when it is paid, all on one timeline for each claim, so your team always knows where every claim stands.

What happens if a claim is rejected?

You see the payer's reason on the claim's timeline, in plain words, so your team knows what to fix before sending it again.

We use a billing company today. Can we switch?

Yes. Your team can run billing on Marathon yourselves, or our team can take it over with full service. Either way, you see every claim on your own dashboard.

Does Marathon check insurance eligibility?

Yes. Marathon checks coverage for upcoming visits, so your front desk knows what a plan covers before the patient sits down.

Does Marathon work for dental groups and DSOs?

Yes. Each location keeps its own data, and one sign-in can see every location it is allowed to, side by side. Groups with 5 or more locations get volume pricing.

How is patient data protected?

We sign a Business Associate Agreement with every office. Data is encrypted in transit and at rest, each office's data is kept separate from every other office, and only people your office invites can see it.
