Anesthesia billing services are the coding, unit calculation, claim submission and payment recovery work that turn every anesthetic you deliver into fully paid revenue. Nevada Medical Billing provides them for anesthesiologists, CRNAs and anesthesia groups in Las Vegas, Henderson, Reno and statewide, with a 98% first-pass clean claim rate.
Every minute documented. Every unit counted. Every modifier defensible under audit.
We review 90 days of cases, units and remittances and show you exactly where revenue is slipping. No contract. No obligation.
Your anesthesiologists and CRNAs deliver precise, high-stakes care in every room. Then a few missing minutes, one wrong modifier or a forgotten nerve block erases part of the payment. These seven leaks surface in almost every anesthesia billing audit we perform.
Anesthesia time begins when the provider starts preparing the patient, not at induction, and it ends when the provider leaves personal attendance. Start the clock late, round down or drop discontinuous time, and you surrender units on every case.
AA pays 100% of the allowable amount; QK, QX and QY pay 50% each. When medical direction is not fully documented, payers reclassify the case as supervision (AD), which pays just 3 base units.
Many commercial payers pay extra units for physical status P3 to P5 and for qualifying circumstances such as emergencies and extreme age. If the claim does not ask for them, the payer will not volunteer them.
Postoperative pain blocks, arterial lines, central lines and TEE are separately payable when documented correctly. Generic billers miss them because they code the anesthetic alone.
Without daily reconciliation against the OR schedule, endoscopy logs and labor and delivery records, cases slip through and never get billed at all.
Each payer pays a different dollar amount per unit. When nobody checks remittances against contracted conversion factors, short payments become permanent losses.
Care team cases generate a physician claim and a CRNA claim. Patients assume they were double billed, call your office and delay payment.

Anesthesia is paid by units, not by a flat procedure fee. Every claim is built from three parts and multiplied by the payer's conversion factor.
(Base units + Time units + Modifying units) × Conversion factor = Payment
Base units reflect the complexity of the anesthesia service. Each surgical CPT code crosswalks to an anesthesia code (00100 to 01999) with a base value from the ASA Relative Value Guide.
Time units come from documented anesthesia minutes. Medicare divides total minutes by 15, while many commercial payers count 15-minute units.
Modifying units are added for physical status and qualifying circumstances by payers that recognize them. Medicare does not.
The conversion factor is the dollar value of one unit. It differs by Medicare locality, Medicaid program and commercial contract.
Worked example: A P3 patient undergoes a procedure with 5 base units and 90 minutes of anesthesia time. With a commercial payer paying $75 per unit, the claim carries 5 base units + 6 time units + 1 physical status unit = 12 units, or $900. Miss 8 minutes and the P3 modifier, and the same case pays less. That gap repeats on every case.
Nevada Medical Billing manages the entire anesthesia revenue cycle or the stages your group wants to hand off. Every workflow is designed for unit-based reimbursement, not borrowed from office billing.
We match every anesthesia record against the OR schedule, endoscopy logs and birthing logs each day, so no case goes unbilled.
We verify coverage, network status and patient responsibility before scheduled cases, and complete self-pay estimates for elective and cosmetic procedures.
Certified anesthesia coders crosswalk each surgical procedure, validate base units, calculate time to the minute and apply every modifier the record supports.
Claims are submitted within 24 to 48 hours of the case after passing payer-specific edits for time, modifiers, concurrency and medical necessity.
We post every remittance line and audit it against your contracted conversion factor, time increments and modifier rules. Underpayments go straight to appeal.
We trace every denial to its root cause, whether time, modifiers, medical direction or medical necessity, then appeal with the anesthesia record and fix the upstream process.
Plain-language statements explain why patients receive physician and CRNA charges, online payment is offered, and a dedicated billing line answers questions in your group's name.
We enroll anesthesiologists, CRNAs and anesthesiologist assistants with Medicare, Nevada Medicaid and commercial plans, and track revalidation dates so no claim denies for enrollment.
Monthly reports on time capture, attestation gaps and units per case give each provider short, specific guidance that lifts revenue without adding charting time.
Anesthesia billing leaves no margin for error. Our coders read the full anesthesia record, including times, attestations, drugs and monitoring, before a claim leaves our hands.
We map each surgical CPT code to the correct anesthesia code and confirm the base value against the current ASA Relative Value Guide, including when a more specific code pays more.
We count from the start of patient preparation to the end of personal attendance, add discontinuous blocks of time and convert minutes the way each payer requires.
| Modifier | Meaning | Payment effect |
|---|---|---|
| AA | Anesthesiologist personally performed | 100% of the allowable amount |
| QY | Anesthesiologist directs one CRNA | 50% to each provider |
| QK | Anesthesiologist directs 2 to 4 concurrent cases | 50% to the physician |
| QX | CRNA or AA with medical direction | 50% to the CRNA or AA |
| QZ | CRNA without medical direction | 100% of the CRNA allowable amount |
| AD | Supervision of more than 4 concurrent cases | 3 base units, plus 1 with induction presence |
| QS | Monitored anesthesia care | Requires documented medical necessity |
| G8 / G9 | MAC for complex procedures or severe cardiopulmonary history | Supports medical necessity for MAC |
| GC | Teaching anesthesiologist with residents | Full payment for 1 or 2 concurrent resident cases |
| 23 / 47 | Unusual anesthesia / anesthesia by surgeon | Payer-specific |
For every QK and QY case, we confirm the 7 TEFRA steps: the pre-anesthetic exam, the anesthesia plan, personal participation in the most demanding parts including induction and emergence, qualified staff for the remaining parts, frequent monitoring, immediate physical availability and post-anesthesia care. A missing step turns a directed case into supervision, so we catch it before the payer does.
We apply P1 to P6 on every claim and bill qualifying circumstance codes 99100, 99116, 99135 and 99140 to payers that pay them, while keeping Medicare claims clean of units it does not pay.
The anesthetic is only part of the story. These services pay on their own when documented correctly.
Peripheral nerve blocks (64415 to 64448), fascial plane blocks such as erector spinae, quadratus lumborum and iPACK, continuous catheters and epidurals (62320 to 62327), billed with 59 or XU when the surgeon requests them for postoperative pain and they are not the primary anesthetic. Daily catheter management is billed with 01996.
Arterial lines (36620), central venous catheters (36556), transesophageal echocardiography (93312 to 93318) and ultrasound guidance (76937, 76942), each supported by its own documentation.
Labor epidurals (01967), cesarean add-ons (01968) and cesarean hysterectomy (01969), with payer-specific rules for counting labor time and daily reconciliation against birthing logs.
When a case is cancelled after the pre-anesthesia evaluation but before induction, we bill the evaluation as an E/M service so the work is still paid.
Main OR, labor and delivery, cardiac and EP labs, interventional radiology and other non-operating-room sites, with stipend and coverage reporting for hospital contract talks.
High-volume, fast-turnover orthopedic, ophthalmology, GI and pain cases, reconciled daily against the surgery center schedule.
MAC and deep sedation for colonoscopy and EGD (00811 to 00813), with correct screening coding so patients keep their zero cost share and claims do not deny.
Plastic surgery, oral surgery and office-based procedures, with self-pay estimates, prepayment collection and clean documentation for any insured portion.
Your staffing model decides your modifiers, your documentation and your payment. We bill each model the way payers expect.
Personally performed cases (AA) with time and units maximized and teaching cases billed with GC.
Anesthesiologist and CRNA or AA claims billed in pairs (QK or QY with QX), with concurrency tracked across rooms and attestations checked case by case.
CRNA services billed with QZ where state law, Medicare supervision rules and facility bylaws allow it. We confirm the supervision requirement at each Nevada facility before the first claim.
One set of rules across hospitals, ASCs and offices, with dashboards by site, provider and payer.
Anesthesia at an in-network facility is protected by the federal No Surprises Act, so patients cannot be balance billed. We dispute low initial payments through 30-business-day open negotiation and independent dispute resolution, with evidence that challenges the payer's qualifying payment amount.
We benchmark your conversion factors, time increments and modifier recognition by payer, then hand your leadership the data needed to negotiate better terms.
Before you staff a new hospital or surgery center, we project collections from its payer mix and case volume, so you know whether to ask for a stipend.
We capture quality data from your anesthesia records and report anesthesia measures such as perioperative temperature management, PONV prevention, multimodal pain management and smoking abstinence, protecting your Medicare payments from MIPS penalties.
We bill Medicare Part B through Noridian (Jurisdiction F), Medicare Advantage plans, Nevada Medicaid fee-for-service and managed care plans, and commercial payers including Anthem Blue Cross Blue Shield, UnitedHealthcare and Health Plan of Nevada, Aetna, Cigna, Humana, Hometown Health and Prominence Health Plan. We also handle TRICARE West, VA Community Care and Nevada workers' compensation claims.
Las Vegas, Henderson, North Las Vegas, Summerlin, Spring Valley and Enterprise hospitals, surgery centers and office-based practices, where high case volume and tight payer contracts reward fast, accurate billing.
Reno, Sparks, Carson City, Minden and Fallon, where regional health plans and a growing Medicare Advantage population make payer-specific rules critical.
Elko, Winnemucca, Ely and Pahrump, including CRNA pass-through eligibility for qualifying low-volume rural hospitals.

Anesthesia billing services cover the revenue cycle for anesthesia providers: case capture, crosswalk coding, time and unit calculation, modifiers, claim submission, payment posting, denial management and patient billing.
Payment equals base units plus time units plus any modifying units, multiplied by the payer's conversion factor. Base units come from the ASA Relative Value Guide, and time units come from documented anesthesia minutes.
Anesthesia time starts when the provider begins preparing the patient for anesthesia and ends when the provider is no longer in personal attendance, usually at the safe transfer of care to recovery.
Medical direction means an anesthesiologist directs up to 4 concurrent cases and completes all 7 TEFRA steps for each one. Supervision covers more than 4 concurrent cases, or cases where the steps are not met, and pays far less.
No. Medicare pays no extra units for P1 to P6 or qualifying circumstances, although the physical status modifier still belongs on the claim. Many commercial payers do pay them, which is why we bill them wherever the contract allows.
Yes, when the block is for postoperative pain, requested by the surgeon and not the primary anesthetic. It is billed with its own CPT code and modifier 59 or XU.
CRNA services are billed with QX when medically directed and QZ when the CRNA works without medical direction. In a directed case, the physician and the CRNA each receive 50% of the allowable amount.
In care team cases, the anesthesiologist and the CRNA each submit a claim. Together they equal roughly what a single provider would be paid, and our patient statements explain this clearly.
Most groups pay a percentage of net collections, typically 4% to 8% across the industry. We quote after the free audit, based on your case volume and payer mix.
Most groups go live in about 30 days, including system access, payer setup and a two-week parallel launch.
