Anesthesia medical billing services

Anesthesia billing uses its own system — base units plus time units plus modifiers — that has nothing in common with surgical coding. Getting paid depends on accurate anesthesia time, correct physical status and medical direction modifiers, and the CRNA and supervision rules that vary by payer.

What makes anesthesia billing different

General billers treat every specialty the same. These are the rules, code families and payer habits that decide whether anesthesia claims pay the first time.

  • Anesthesia codes (00100–01999) carry base units; time units are calculated from documented start and stop times in 15-minute increments or by payer rule.
  • Medical direction modifiers (AA, QK, QY, QX, QZ) depend on who provided and who supervised, and the number of concurrent cases.
  • Physical status modifiers (P1–P6) add units with many commercial payers but not Medicare.
  • Qualifying circumstances and monitored anesthesia care (QS, G8, G9) have specific documentation requirements.

Denials we see most in anesthesia

Every denial gets a root cause, a fix and a feedback loop, so the same denial stops coming back.

Time calculation disputes

Claims underpaid for time rounding or missing start/stop documentation. We bill from documented times under each payer's rules.

Modifier errors

Medical direction denied for wrong modifier or concurrency. We verify staffing per case.

Physical status unpaid

P modifiers omitted. Applied where the payer recognizes them.

Anesthesia billing questions

How is anesthesia billed differently from surgery?

By base units for the procedure plus time units from documented anesthesia time, modified by who provided and supervised the care. It is a separate system entirely.

What are medical direction modifiers?

Modifiers that describe whether an anesthesiologist personally performed, directed CRNAs, or a CRNA worked independently, and how many cases ran concurrently. Payment depends on them.

Do you bill for CRNA groups?

Yes, under the modifier and supervision rules each payer and state applies.
