Professional Anesthesia Billing Services
Anesthesia medical billing is specialty billing and revenue cycle work built for anesthesiologists, CRNAs, and anesthesia groups where a case with the wrong provider modifier, a start-and-stop time that doesn't tie out to the record, or a MAC case coded like general anesthesia is the difference between a paid claim and an underpayment nobody ever catches.
EverCure Billing handles the complete revenue cycle for anesthesia providers across the United States: eligibility and benefit checks, prior authorizations, anesthesia coding, unit calculation, claim submission, denial appeals, and aged A/R recovery. Your team runs the case. We make sure the base units, time units, qualifying circumstances, and provider modifiers you already earned actually get paid and hold up if a payer looks.
What Is Anesthesia Medical Billing?
Anesthesia medical billing covers every financial step between a case being scheduled and that money landing in your practice account.
For an anesthesia practice specifically, that includes verifying the patient's benefits and surgical coverage, obtaining prior authorization where the payer requires it, assigning the correct anesthesia CPT and matching it to the surgical procedure, capturing anesthesia start and stop time, calculating base units plus time units plus any qualifying-circumstance units, applying the right provider modifier for who did the work and how it was supervised, submitting a clean claim, posting the payment against the payer's conversion factor, appealing when the payer underpays or denies, and chasing the balance until it clears.
General medical billing bills a flat procedure. Anesthesia billing runs on a formula (base units + time units + qualifying circumstance units) × conversion factor and every input in that formula has to be documented and defensible. That makes anesthesia one of the easiest specialties to underbill without ever noticing, because the money leaks a few units at a time.
Why Do Anesthesia Practices Lose More Revenue Than They Should?
Because anesthesia pays on units and modifiers, not on a fixed fee and a small error in time capture, provider modifier, or physical-status reporting quietly shaves dollars off every case. These are the specific leaks we see when we run audits on anesthesia practices:
Time-unit capture errors
Anesthesia time runs from when you begin preparing the patient to when you hand off care. When start-and-stop times aren't recorded cleanly, or rounding is done inconsistently, the practice under-collects on long cases and can't defend the time on audit. Over a year of cases, those missing minutes add up to real money.
Wrong or missing provider modifier
AA, QK, QY, QZ, QX, and QS each tell the payer exactly who performed the anesthesia and how it was supervised and each pays differently. Bill medical direction as personally performed, or miss the supervision modifier entirely, and the claim either denies or pays at the wrong rate.
MAC cases coded like general anesthesia
Monitored anesthesia care has its own modifier and documentation expectations. Code a MAC case without the QS modifier and the supporting note, and the claim gets scrutinized or downpaid.
Missed qualifying circumstances
Extreme age, emergency conditions, unusual positioning, and hypothermia carry extra units but only if they're coded and documented. Most practices simply never capture them, leaving earned units on the table on every qualifying case.
Physical-status reporting gaps
ASA physical status (P1–P6) affects reimbursement for many payers. When the status isn't documented and reported, higher-acuity cases get paid like routine ones.
Base-unit and surgical-crosswalk mismatches
Every anesthesia CPT carries a base unit that reflects the complexity of the surgery. Cross the case to the wrong anesthesia code and the base units and the whole claim come out wrong.
We build the workflow around these six failure points, because they are where anesthesia revenue actually disappears.
What Anesthesia Billing Services Does
EverCure Billing Provide?
Insurance eligibility and benefits verification
We verify active coverage, plan type, deductible status, coinsurance, and surgical benefit before the case, so anesthesia isn't delivered on a claim that was never going to pay.
Prior authorization support
We prepare and submit authorization requests where the payer requires them for the surgical case or MAC service, attach the clinical documentation, and follow up with the payer until a decision is issued.
Anesthesia coding and unit calculation
Our coders cross the surgical procedure to the correct anesthesia CPT, assign base units, calculate time units from documented start-and-stop time, add qualifying-circumstance units where supported, and apply the correct provider and physical-status modifiers. Coding and billing are handled together, so unit and modifier errors are caught before the claim goes out, not after it's audited.
Charge entry and claim scrubbing
Every claim runs through a pre-submission check for base-unit accuracy, time-unit math, provider-modifier logic, physical-status reporting, and payer-specific edits before it leaves our office.
Claim submission and clearinghouse management
Electronic submission, rejection handling at the clearinghouse level, and same-day correction and resubmission on front-end rejects.
Payment posting and reconciliation
ERA and manual EOB posting, conversion-factor verification, and underpayment identification because anesthesia is one of the easiest specialties for a payer to underpay on units, and most practices never catch it.
Denial management and appeals
Every denial is categorized by root cause, corrected, and appealed with the documentation the payer is actually asking for. We also feed denial patterns back into coding so the same denial stops repeating.
Accounts receivable follow-up and recovery
Structured follow-up on aged claims by bucket (30 / 60 / 90 / 120+ days), with priority given to high-unit and high-dollar cases and anything approaching a timely filing deadline.
Patient billing and support
Clear patient statements, balance explanations, and a support line so your front desk isn't fielding coverage questions all day.
Provider credentialing and payer enrollment
New provider enrollment, re-credentialing, CAQH maintenance, and Medicare enrollment through PECOS so a new anesthesiologist or CRNA isn't sitting idle waiting on a panel.
Billing audits and compliance review
Periodic internal review of time documentation, modifier usage, and medical necessity to reduce audit exposure before a payer finds it first.
Financial reporting
Monthly reporting on collections, clean claim rate, denial rate by reason, days in A/R, and payer performance in plain language, not a data dump.
Which Anesthesia Services
Do You Bill?
General anesthesia full anesthesia for major surgical procedures, crossed to the correct anesthesia CPT with accurate base units and time.
Regional anesthesia spinals, epidurals, and peripheral nerve blocks, coded with the correct provider modifier and, where separately billable, the block itself.
Monitored anesthesia care (MAC) sedation cases coded with the QS modifier and physical-status reporting so they pay correctly and survive review.
Local anesthesia and procedural sedation coded and documented for the setting and provider so the service is reimbursed rather than absorbed.
Obstetric anesthesia labor epidurals and cesarean anesthesia, with the time and unit rules that obstetric cases require.
Pain management procedures where your anesthesiologists perform interventional pain services, billed with the correct procedure and modifier logic alongside the anesthesia work.
Qualifying-circumstance cases extreme age, emergency, and unusual-condition cases coded to capture the extra units the case actually earned.
Which Anesthesia CPT and ICD-10 Codes
Do You Work With?
| Code / Range | What It Covers |
|---|---|
| 00100–01999 | Anesthesia procedure codes, crossed from the surgical CPT |
| 00300 | Anesthesia for procedures on the neck / integumentary |
| 00400 | Anesthesia for procedures on the anterior abdominal wall |
| 00790 | Anesthesia for upper-abdomen intraperitoneal procedures |
| 01112 | Anesthesia for lower-leg / knee procedures |
| 01967–01969 | Neuraxial labor and cesarean anesthesia |
| 99100 | Qualifying circumstance extreme age |
| 99116 | Qualifying circumstance total body hypothermia |
| 99135 | Qualifying circumstance controlled hypotension |
| 99140 | Qualifying circumstance emergency conditions |
| 62320–62327 | Epidural / subarachnoid injections (where separately billable) |
| 64400–64489 | Peripheral nerve blocks (where separately billable) |
Base units, the annual anesthesia conversion factor, and payer supervision rules all update over time. Keeping current on all three is part of the service, not an extra.
Which Modifiers and Codes Actually Decide
Whether an Anesthesia Claim Gets Paid?
More than any other specialty, the provider modifier decides the payment in anesthesia because it tells the payer who did the work and how it was supervised.
Anesthesia personally performed by the anesthesiologist. Highest allowance; has to match the record.
Medical direction of two, three, or four concurrent cases by the anesthesiologist. The concurrency has to be documented.
Medical direction of one CRNA by an anesthesiologist.
CRNA service with medical direction by a physician.
CRNA service without medical direction. Common, and paid differently so it has to be correct.
Monitored anesthesia care. Flags a MAC case and pairs with the physical-status and documentation.
ASA physical status. Reports the patient's acuity; drives extra units for many payers on higher-status cases.
MAC for deep complex, or MAC for a patient with a history of severe cardiopulmonary condition, where the case supports it.
The theme in anesthesia is that provider-modifier accuracy, clean time capture, and physical-status reporting decide payment far more than the anesthesia CPT itself. That's exactly what we scrub before submission.
How Does Compliance Work in Anesthesia Billing?
Time documentation
Time units are only defensible when the anesthesia record supports the start-and-stop time billed. We build clean time capture into the workflow so time units stand up to review.
Medical-direction discipline
Medical-direction modifiers (QK, QY, QX) require the anesthesiologist's presence and the "seven steps" to be documented. We hold the modifier logic to the documentation standard so concurrent cases are billed correctly and survive scrutiny.
MAC and physical-status accuracy
MAC cases and higher physical-status levels are reviewed patterns. We tie the QS modifier and the P-status to the note so they're supported.
Medical necessity
Qualifying circumstances and physical status carry medical-necessity expectations. We link the case facts to the documentation so units aren't submitted unsupported.
HIPAA and data security
Every EverCure Billing team member works under signed HIPAA agreements with role-based access to PHI, secure data transfer, and no PHI on personal devices or unsecured channels.

What Does Anesthesia Billing Cost?
Our anesthesia billing services are priced as a percentage of monthly collections so our revenue only grows when yours does. Your exact rate depends on case volume, payer mix, supervision model, and which parts of the cycle you want us to handle.
There are no setup fees and no long-term lock-in contracts. If you want a specific number, the Business Assessment is the fastest way to get one that's accurate rather than generic.
Why Choose EverCure Billing for Anesthesia Billing?
We code and bill together.
In anesthesia, most lost revenue is a coding decision a missed qualifying circumstance, the wrong provider modifier, sloppy time capture. Handling coding and billing in one workflow means those errors are caught before the claim drops, not surfaced later in an audit.
We handle the unit math, not just the claim.
Base units, time units, qualifying circumstances, and conversion-factor verification take real attention. That's the work we don't round it off and move on.
You get a named account manager, not a ticket queue.
One person who knows your practice, your facilities, and your payers, reachable directly.
Direct access to leadership.
When something goes wrong, you're not escalating through four layers to get an answer.
Denial data goes back into coding.
Every denial reason is tracked and fed back upstream so the same error stops repeating.
Transparent reporting.
You see clean claim rate, denial rate by reason, days in A/R, and collections every month, explained clearly.
No long-term contracts.
We keep your business by performing, not by locking you in.
Is Your Anesthesia Practice Leaving Money on the Table?
Most anesthesia practices don't know how many qualifying-circumstance units they're missing, how often their provider modifiers are wrong, or how much of their aged A/R is still collectible until someone actually looks.
That's what the Business Assessment is for. We review your recent cases, denials, and A/R and give you a written breakdown of what's recoverable and what's causing the leak. No cost, no obligation.
