Read the first 7 Anesthesia Coding flashcards as text

  1. Which formula is used to calculate anesthesia reimbursement?

    Answer: (Base units + Time units + Modifying units) × Conversion factor

    The standard anesthesia payment formula is (B + T + M) × CF, where B=base units, T=time units, M=modifying units, and CF=the payer's conversion factor.

  2. How are anesthesia time units typically calculated by most payers?

    Answer: One unit per 15 minutes of anesthesia time

    Most payers, including Medicare, use one time unit per 15 minutes, counting from anesthesia induction until the patient is safely transferred to post-anesthesia care.

  3. What does anesthesia physical status modifier P3 indicate about the patient?

    Answer: A patient with severe systemic disease

    P3 designates a patient with severe systemic disease that is not incapacitating, adding one modifying unit to the anesthesia calculation.

  4. Which CPT code range covers anesthesia services?

    Answer: 00100–01999

    Anesthesia CPT codes are found in the range 00100–01999, organized by anatomical site of the surgical procedure.

  5. Monitored Anesthesia Care (MAC) is best described as:

    Answer: Sedation monitoring by an anesthesiologist with ability to convert to general anesthesia if needed

    MAC involves an anesthesia provider monitoring the patient and administering sedation while remaining ready and able to convert to general anesthesia if required.

  6. A patient classified as anesthesia physical status P5 is best described as:

    Answer: A moribund patient not expected to survive without the operation

    P5 designates a moribund patient who is not expected to survive without the operation, adding 3 modifying units to the anesthesia billing formula.

  7. Anesthesia qualifying circumstance code 99100 is reported when anesthesia is provided to:

    Answer: A patient under 1 year or over 70 years of age

    Code 99100 is reported for extreme age patients (under 1 year or over 70 years), reflecting the increased complexity of anesthesia for these populations.
