Billing That Accounts for Every Minute in the Operating Room

The foundation of every anesthesia claim is the correct calculation of base units and time units. Base units are assigned to the surgical procedure being supported, while time units are calculated based on the total minutes of anesthesia care provided. An error in either calculation, whether it is the wrong base unit value or an inaccurate time recording, directly reduces reimbursement on every affected case. At Medisure, we verify base unit values against current anesthesia crosswalk tables for every procedure and calculate time units based on accurate start and stop times documented in the anesthesia record, ensuring that every case pays exactly what it should.

Beyond base and time units, anesthesia reimbursement is also affected by physical status modifiers that reflect the complexity of the patient's condition and qualifying circumstance codes that account for factors like extreme age, emergency conditions, and controlled hypotension. These modifiers add units to the claim and increase reimbursement, but they are frequently missed or incorrectly applied. At Medisure, we review every anesthesia record for applicable physical status and qualifying circumstance modifiers and apply them correctly on every claim, capturing additional reimbursement that many practices routinely leave behind.

Anesthesiology practices that employ Certified Registered Nurse Anesthetists face an additional layer of billing complexity around medical direction and supervision rules. The distinction between personally performed anesthesia, medically directed CRNA cases, and medically supervised cases determines which modifiers apply and what percentage of the fee schedule is reimbursable. Getting this wrong is both a revenue issue and a compliance risk. Medisure handles CRNA and medical direction billing with full compliance awareness, applying the correct modifiers based on the actual supervision model used for each case and ensuring that your practice collects correctly without exposing itself to audit risk.

Anesthesia claims are denied for reasons that are unique to this specialty, including time discrepancies between the anesthesia record and the operative report, incorrect base unit values, missing physical status modifiers, and payer-specific anesthesia fee schedule disputes. At Medisure, we address these issues proactively through detailed pre-submission audits that cross-reference anesthesia records with operative reports and verify all claim components before submission. When denials do occur, our team responds immediately with the documentation and appeal needed to resolve them quickly.

Anesthesiology practices need financial reporting that reflects the unique structure of anesthesia billing, breaking down performance by procedure type, case complexity, physical status distribution, and payer mix. At Medisure, we provide detailed monthly revenue cycle reports that give anesthesiologists and practice administrators full visibility into their financial performance. We monitor AR closely, follow up on every outstanding case, and work proactively to keep your revenue cycle running at peak efficiency so your anesthesiologists can stay focused on keeping patients safe in the operating room.
