Specialty billing · Ambulance & EMS
The claim is built in the field, mid-emergency, by a crew who will never see the remittance.
247 Medical Billing Services turns more of your transports into first-pass payments with ambulance billing services built for ground EMS, non-emergency, air-medical, and interfacility runs across Medicare, Medicaid, commercial, and auto payers. A dedicated account manager owns your account, a free 360° reporting dashboard shows every claim, and every run is handled under HIPAA and SOC 2 Type II safeguards — specialist EMS billing since 2005.
Payment is a base rate plus loaded mileage off the national Ambulance Fee Schedule, priced by an A-code level of service, and stamped with a two-character origin/destination modifier where the first letter is where the run started and the second is where it ended.
BLS, BLS-Emergency, ALS1, ALS1-Emergency, ALS2, Specialty Care Transport, and Paramedic Intercept — the correct level read from the crew narrative, with ALS assessment and intervention documentation defended against downcoding.
Ground mileage per loaded statute mile, and fixed- or rotary-wing air mileage. Loaded miles only, reconciled to the CAD record and reported to the nearest tenth.
First character origin, second character destination — RH, SH, NH, RG and the rest. The correct pairing on every line, with non-covered destinations caught before submission.
Covered only when other means of transport were contraindicated, with the nearest-appropriate-facility rule limiting payable mileage — documented from the run report, not from "bed-confined" alone.
We manage every element of the transport claim so each run is paid to its true value — the correct level, the right modifier, and every loaded mile captured:
| Claim element | What it is | What we manage |
|---|---|---|
| Level of service (A-codes) | BLS (A0428), BLS-Emergency (A0429), ALS1 (A0426), ALS1-Emergency (A0427), ALS2 (A0433), Specialty Care Transport (A0434), Paramedic Intercept (A0432) | The correct level read from the crew narrative, with ALS assessment and intervention documentation defended against downcoding |
| Loaded mileage | Ground mileage per loaded statute mile (A0425); air mileage FW (A0435) / RW (A0436) | Loaded miles only, reconciled to the CAD record, reported to the nearest tenth |
| Origin/destination modifier | A paired two-character modifier — first char origin, second char destination (e.g., RH residence to hospital, SH scene to hospital, NH SNF to hospital, RG residence to hospital-based dialysis) | The correct pairing on every line, with non-covered destinations caught before submission |
| Medical necessity | Covered only when other means of transport were contraindicated; nearest-appropriate-facility rule limits payable mileage | Necessity documented from the run report, not from "bed-confined" alone |
| PCS / prior authorization | Physician Certification Statement for non-emergency transport; RSNAT prior authorization for repetitive scheduled non-emergent runs | Timely PCS capture and RSNAT authorization secured before the run is billed |
| Air transport | Fixed-Wing (A0430) and Rotary-Wing (A0431) base rates set directly, plus air mileage | Documented ground-was-contraindicated necessity, and out-of-network disputes routed through the correct process |
A transport claim looks nothing like the line items most billing companies are built to process, because the payment is assembled from a coding stack found nowhere else in medicine — and each input is a place to win or lose the run:
Payment is base rate plus mileage, off a national fee schedule. Reimbursement is a level-of-service base rate (RVU-weighted, geographically adjusted) plus a separate per-loaded-mile amount. Only patient-loaded miles are payable — response and deadhead miles are not — and mileage is reported to the nearest tenth. Bill flat charges and you leave the mileage math, and the rural add-ons, on the table.
The level of service is a documentation fight, not a checkbox. BLS versus ALS1 turns on whether an ALS assessment or intervention was warranted; ALS1 versus ALS2 turns on the intervention count. Payers downcode ALS to BLS the moment the crew narrative doesn't substantiate it, and that downcode is pure margin lost.
Every line needs a paired origin/destination modifier. The two-character modifier — first character origin, second character destination — has to match the actual trip, and the wrong pairing or a non-covered destination is an automatic rejection.
Medical necessity has its own standard. Coverage exists only when transport by any other means was contraindicated. "Bed-confined" is one factor, not a free pass — documenting only bed-confinement is a classic denial trigger.
The Patient Care Report is the entire clinical and billing record, and the beneficiary often can't sign at the scene.
The biller frequently starts with a name and a pickup address
Downstream beneficiary and representative signature workflows, run after the transport rather than abandoned at the scene.
Receiving-facility face-sheet retrieval turns a name and an address into a complete, billable claim.
Recovering those transports is operational work a general biller simply doesn't do — so it becomes a write-off instead of revenue.
Every one of those variables is where an EMS agency quietly loses revenue — and every one is exactly what professional ambulance billing services are set up to close.
Ambulance is one of the hardest revenue cycles to run in-house, because the billing rules live nowhere near the crew that generates the claim. A dispatcher, a paramedic, and a station chief are not fee-schedule experts, yet every payable dollar depends on a level of service, a paired origin/destination modifier, a loaded-mile count, and a medical-necessity narrative being right the first time.
Ambulance runs on thin margins, a heavy Medicare and self-pay mix, and constant program-integrity scrutiny — one missing Physician Certification Statement or one unloaded mile can surface as a recoupment months after the run.
A specialist ambulance billing services company absorbs that risk on a fee tied to what we actually collect, so your cost scales with revenue instead of sitting fixed while denials pile up. When you outsource to a team that does only this, the fee schedule, the A-codes, and the PCS and RSNAT rules stop being a part-time burden on people who should be running calls.
Everything it takes to move a transport from the run report to paid, run by one certified team rather than split across vendors:
The A-code base matched to the documented ALS assessment, intervention count, or SCT criteria, paired with the correct origin/destination modifier and loaded mileage only.
The run-report narrative reviewed for the "other transport contraindicated" standard, the Physician Certification Statement captured on non-emergency transports, and RSNAT prior authorization secured for repetitive dialysis and wound-care runs before the third round trip becomes unbillable.
Downstream beneficiary/representative signature workflows and receiving-facility face-sheet retrieval that recover transports a generalist writes off as unbillable.
Coverage, network status, and payer confirmed before or immediately after the run, including auto/PIP and workers'-comp first-party coverage that often pays above Medicare.
From ALS-to-BLS downcodes to medical-necessity and modifier rejections, with air-ambulance out-of-network disputes handled through the No Surprises Act arbitration process.
Old claims pursued relentlessly across Medicare, Medicaid, commercial, auto, and a high self-pay share, with a compliant patient-collections workflow on the balances.
Enrollment and revalidation kept current so nothing rejects on supplier eligibility or an expired enrollment.
Coders sitting beside your billers, so the A-code, the modifier, and the necessity narrative stay aligned instead of being handed between companies.
Prefer ambulance billing and coding services under one roof? That's exactly the model — certified coders and billers sharing the same run report, instead of routing your claims between vendors.

Bringing us on isn't hiring a general biller who happens to accept transport claims. It's hiring a dedicated ambulance billing company that already knows where EMS revenue leaks and how to stop it:
Cycle after cycle, not just the quarter after you switch:
A generalist learns ambulance on your claims. We show up already fluent in the fee schedule, the A-codes, and the modifier system — and the difference shows up on the remittance:
Most ambulance losses trace back to the same handful of failure points — and ambulance is a top program-integrity target, so several of them carry audit exposure, not just a denial. We close each one at the front end, before it becomes a takeback:
Necessity documented only as "bed-confined"
Medical-necessity denial ("could have gone by other means") — the #1 recurring denial
We document why other transport was contraindicated, from the run report, on every claim
Missing or late Physician Certification Statement
Non-emergency transport denial and False Claims Act exposure
We capture a valid PCS dated within the required window before the run is billed
Repetitive transport billed without RSNAT prior authorization
Prepayment review and denial after the third round trip in 30 days
We secure RSNAT authorization for dialysis and wound-care runs before billing stops
Wrong or missing origin/destination modifier
Automatic rejection — every line requires the paired modifier (e.g., NH, RH, HN)
We apply the correct two-character modifier and catch non-covered destinations pre-submission
ALS billed without documented assessment or intervention
ALS-to-BLS downcode and lost margin
We defend the level with the documented ALS assessment, intervention count, or SCT criteria
Unloaded or inflated mileage (A0425)
Mileage denial or overpayment/recoupment
We bill loaded miles only, reconciled to CAD, reported to the nearest tenth
Every one of these is preventable before submission rather than argued after the fact. Request a revenue review and we'll show you which of them is hitting your remits right now.
The rules shift with the operator and the setting, and we bill each one to the detail it demands:
Public, private, and fire-based services where high-volume emergency responses live or die on clean first-pass level-of-service coding.
What decides the moneyFirst-pass level-of-service coding
Scheduled dialysis, wound-care, and discharge runs where the PCS, RSNAT prior authorization, and medical-necessity narrative decide whether the transport is payable at all.
What decides the moneyWhether it is payable at all
Interfacility movement of critically ill patients requiring care beyond paramedic scope, where documentation has to substantiate the higher level.
What decides the moneyDocumentation for the higher level
Fixed-wing and rotary-wing services where base rates are set directly and out-of-network balance billing runs through federal No Surprises Act arbitration.
What decides the moneyThe arbitration, worked not accepted
Transport programs that need billing integrated with the receiving facility's face sheet and demographics.

Changing billers shouldn't cost you a cycle of cash, and here it doesn't.
We work inside your existing ePCR and ambulance billing platform, so nobody has to relearn a system.
Credentialing and payer-enrollment review run in parallel while your claims keep going out the door, and a named account manager leads the transition from day one.
Most agencies are fully live within a few weeks.
The denial drop and the faster A/R show up in the first cycles — not a quarter later.
More of your transports pay on the first pass.
The level defended, the paired modifier correct, every loaded mile captured. We run the whole transport revenue cycle: eligibility on a name and an address, the A-code read from the run report, loaded miles reconciled to the dispatch record, the origin/destination pairing checked, and the medical-necessity narrative built to the standard payers actually apply. Because transport claims are all we do, the fee schedule and the certification workflow are routine rather than a scramble that pulls crews off calls. Agencies that move their medical billing to us typically see denials fall by up to 40%, clean claims near 99%, net collections near 99%, and days in A/R under 25 — with recoupment risk kept off the books.
