Billing for anesthesiology is unlike any other medical specialty. Unlike other providers who bill based on procedure codes alone, anesthesiologists must consider base units, time units, modifiers, and qualifying circumstances — all of which can significantly impact reimbursement.
Anesthesiology Medical Billing Services
At Smart RCM Solutions, we specialize in handling the complexities of anesthesia billing. Our goal is to ensure every minute, modifier, and unit is billed accurately — so your practice receives full and timely reimbursement.
Why Anesthesia Billing Is So Complex
Anesthesiology billing combines multiple layers of data:
- Base Units: Assigned based on the surgical procedure
- Time Units: Calculated from anesthesia start to end time
- Modifiers: Indicate type of provider (AA, QX, QZ, etc.)
- Qualifying Circumstances: Add-on codes for special conditions (extreme age, emergency, etc.)
- Physical Status Modifiers: Reflect patient’s health condition (P1–P6)
Missing or incorrect information in any of these categories can result in underpayment or denial — which is why anesthesiology billing demands expert handling.
Our Anesthesia Billing Services Include:
✅ Accurate Base & Time Unit Calculation
We use your anesthesia records to compute the exact anesthesia time, apply the correct base units (per CPT), and factor in conversion rates.
✅ Modifier Application & Compliance
We apply the correct modifiers (AA, QX, QK, QZ, AD) depending on whether services were personally performed, medically directed, or supervised.
✅ Claims Submission & Follow-Up

FAQs About Anesthesia Billing
Q: How are anesthesia services billed?
Anesthesia is billed based on base units (per ASA/CPT code), time units (start to end), and modifying units (status, circumstances, complexity). These are multiplied by a conversion factor set by payers.
Q: What is the AA modifier?
AA indicates that anesthesia services were personally performed by the anesthesiologist. It typically results in full reimbursement.
Q: Can a CRNA bill without supervision?
Yes, in some states CRNAs can bill independently using the QZ modifier. However, rules vary by payer and state regulations.
Q: What causes most anesthesia claim denials?
Top reasons include missing start/end times, wrong modifier usage, lack of documentation for qualifying circumstances, and failure to follow payer-specific guidelines.
Q: Do you work with hospitals and surgery centers?
Yes — we provide customized anesthesia billing for hospitals, ASCs, and large group practices with both physicians and CRNAs.
