Anesthesia billing is one of the most complex areas of medical billing—driven by time, patient condition, and procedure complexity. At Mastermind Healthcare, our anesthesia billing specialists help practices recover up to 28% more revenue through accurate unit calculation, modifier use, and ASA coding.
What Is Anesthesia Billing?
Anesthesia billing involves submitting claims for anesthesia services during surgeries using a unique formula: Total Units = Base Units + Time Units + Modifiers. Payers like Medicare and commercial insurers require precise documentation of start/end times, ASA physical status, and qualifying circumstances.
Key Components
- Time-Based Units: 1 unit = 15 minutes of anesthesia time (e.g., 60 minutes = 4 units).
- Base Units: Predefined by ASA for each CPT code (e.g., 00840 = 10 base units for knee surgery).
- ASA Physical Status Modifiers: P1–P6 indicate patient risk (P3 = severe systemic disease).
- Qualifying Circumstances: Add-on codes like 99100 (extreme age) or 99140 (emergency) boost reimbursement.
Common Challenges & Solutions
- ❌ Inaccurate Time Tracking: → We sync with your EHR to auto-capture anesthesia start/end times.
- ❌ Missing Modifiers: → Our team applies P1–P6 and qualifying circumstance codes correctly.
- ❌ Undercoded Base Units: → We audit CPT-to-base-unit mapping to prevent revenue leakage.
Why Specialized Expertise Matters
A single undercoded case (e.g., missing 2 time units) can cost $120–$200 in lost revenue. Over a month, that’s thousands. Our team ensures every unit is captured—so you get paid what you’re owed.
