What is the standard formula used by most payers to determine the total units for anesthesia services, and what does each component represent?
Show answer →Formula: (B + T + M). B = Base Units: Assigned by the ASA based on complexity (includes pre-op and post-op visits). T = Time units: Calculated from when the anesthesiologist begins to prepare the patient until the patient is no longer under their professional care. M = Modifying units: Includes Physical Status modifiers (P1-P6) and Qualifying Circumstances (e.g., extreme age, hypothermia). CCS Exam Tip: Note that the Conversion Factor (CF) is applied after units are summed to determine dollar reimbursement. AHIMA often tests the definition of Base units specifically.
A 1-year-old infant (age 14 months) undergoes a procedure under general anesthesia. Can the Qualifying Circumstances code +99100 be reported in addition to the anesthesia code?
Show answer →No. CPT +99100 (Anesthesia for patient of extreme age, under 1 year and over 70) is only for patients under 1 year of age OR over 70. Since the infant is 14 months, they do not meet the criteria. CCS Tip: Always check the specific age requirements for +99100. Also, remember that if the primary anesthesia code already includes age in its descriptor (e.g., 00326), you cannot report +99100 separately.
Anesthesia is induced for a planned total hip arthroplasty, but the surgeon cancels the procedure due to an equipment failure before the incision. How is this reported?
Show answer →Report the anesthesia code (01214) with modifier -53 (Discontinued Procedure). Documentation must show that anesthesia was started. Units: Report the actual time spent with the patient until the procedure was terminated. CCS Strategy: If the procedure is canceled PRIOR to induction of anesthesia, do not report an anesthesia code; instead, a pre-operative evaluation (E/M) might be appropriate. Modifier -53 is used for the physician's professional component.
A patient with a history of COPD and a BMI of 42 presents for surgery. Documentation indicates the patient has substantive functional limitations due to these conditions. Assign the correct modifier.
Show answer →P3. Rationale: P3 is for patients with severe systemic disease and substantive functional limitations. This includes BMI >40, poorly controlled DM or HTN, COPD, or history (>3 months) of MI, CVA, or TIA. Key for CCS: BMI over 40 automatically moves a patient to P3 in current standards.
A patient who suffered an acute myocardial infarction 2 months ago requires urgent gallbladder surgery. Which physical status modifier is most appropriate for the anesthesia coding?
Show answer →P4. Rationale: P4 is for severe systemic disease that is a constant threat to life. This includes a recent (<3 months) MI, CVA, TIA, or CAD/stents. If the MI was >3 months ago, the patient would likely be P3 (provided they are stable). CCS Strategy: Pay close attention to the 3-month threshold for cardiac events.
