This is a heading to set the tone for the block

At nimble, we understand surgical care starts at a physician’s clinic before surgeons and anesthesiologists see patients in the operating room. Our Total RCM solution serves ambulatory surgery centers, surgical clinics, surgical hospitals, and anesthesia groups.

This is a heading to set the tone for the block

As back-office support of an ASC or surgical hospital operating room is so closely linked to the back-office support of affiliated surgical clinics and anesthesia groups, we strive to identify and unlock efficiencies throughout the revenue cycle process by leveraging our fully integrated, tech-enabled RCM workflow tools.

Surgical RCM Designed to Maximize Cash Per Case

Revenue Leakage

As a highly trained specialist, you operate in a world with a complex claims system. Highest dollar claims are important, but is there leakage in your process that’s resulting in lost revenue?

Claims Matching

If your patient is diagnosed at your clinic before seeing you and your affiliated anesthesiologist in the operating room, shouldn’t patient, billing, and coding information across those claims all match?

Staffing Challenges

Workforce challenges are no secret in today’s marketplace. Access a team of surgical RCM experts to eliminate the never-ending process of recruiting, hiring, and training personnel.

Complex Processes

Combinations of changing personnel, homegrown technology, and third-party resources can result in suboptimal workflows leading to inefficient billing and revenue leakage.

Frequently Asked Questions

Anesthesia billing is calculated using a unit-based methodology that includes base units assigned to the anesthesia CPT code, time units derived from documented anesthesia start and stop times, and applicable modifying units. Total units are multiplied by a conversion factor that varies by payer.

Anesthesia claims are frequently denied due to time documentation issues, incorrect modifier selection, missing medical direction records, or payer-specific billing rules. Because anesthesia reimbursement depends on multiple variables, even small documentation or coding errors can trigger denials or underpayment.

Medical direction modifiers require clear documentation of the anesthesiologist’s involvement, including pre-anesthesia evaluation, presence during induction and emergence, monitoring at frequent intervals, and availability throughout the procedure. Concurrency limits must also be supported by the record.

Before managing anesthesia billing internally, organizations should assess whether they have access to anesthesia-certified coders, ongoing education resources, auditing capabilities, and processes to manage payer rule variation. Without these, in-house billing can introduce revenue loss and compliance risk rather than savings.
