Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- For services that require a referring/ordering physician, the referring/ordering physician's name and NPI must be reported on the claim.
- The claim must include a valid ICD-10-CM diagnosis code that best describes the patient's condition for which the urine drug test was performed.
- For diagnostic urine drug tests, report the test result if known; if the result is not known, report the symptoms that prompted the performance of the test.

Key Coverage Criteria
- Ambulatory continuous EEG is covered only if a prior routine “resting” EEG was performed before the ambulatory EEG.
- Routine EEGs covered under this policy are those described by CPT codes 95812, 95813, 95816, 95819, or 95822.
- A routine EEG is defined as a recording of less than a 24-hour continuous duration.
- 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.
