T41.1X5S — Adverse effect of intravenous anesthetics, sequela
ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- The medical record must contain documentation fully supporting medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
- Each echocardiography service requires a formal written report with interpretation retained in the record and copies of image documentation (paper or electronic) available for review.
- A complete study must include M-mode and/or 2D measurements of LV end-diastolic diameter, LV end-systolic diameter, LV wall thickness, left atrial diameter, aortic valve excursion, and a qualitative description of LV function, or valid substitutes such as LV volumes, ejection fraction, and mass.
- Doppler interrogation must state the modes used and provide both qualitative and quantitative information.
Key Coverage Criteria
- Transthoracic echocardiography (TTE) is covered when the patient's medical record documents medical necessity consistent with the LCD indications for TTE.
- Contrast (contrast-enhanced) echocardiography is covered when conventional echocardiographic studies were inconclusive and contrast enhancement is needed to complete diagnostic evaluation.
- Repeat echocardiographic studies are covered to monitor changes in cardiac structure or function when there is a change in clinical status or when disease progression is suspected.
- RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
- Monitored Anesthesia Care (MAC) is medically necessary when the patient has one or more documented diagnoses listed as supporting medical necessity (e.g., F91.9, G97.81, T81.9XXA, T88.8XXA, F79) and the diagnosis is matched to the anesthesia/CPT/HCPCS procedure performed.
- Use G9 anesthesia modifier to indicate need for MAC due to a history of severe or advanced cardiopulmonary disease when the proceduralist determines additional monitoring is required.
