NCDs and coverage provisions in interpretive manuals are not subject to the Local Coverage Determination (LCD) Review Process (42 CFR 405.860[b] and 42 CFR 426 [Subpart D]). In addition, an administrative law judge may not review an NCD. See Section 1869(f)(1)(A)(i) of the Social Security Act.Unless otherwise specified, italicized text represents quotation from one or more of the following CMS sources:Title XVIII of the Social Security Act (SSA):Section 1862(a)(1)(A) excludes expenses incurred for items or services which are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member.Section 1862(a)(7) excludes routine physical examinations, unless otherwise covered by statute.Section 1833(e) prohibits Medicare payment for any claim which lacks the necessary information to process the claim.Code of Federal Regulations:42 CFR, Section 410.32, indicates that diagnostic tests may only be ordered by the treating physician (or other treating practitioner acting within the scope of his or her license and Medicare requirements) who furnishes a consultation or treats a beneficiary for a specific medical problem and who uses the results in the management of the beneficiary's specific medical problem. Tests not ordered by the physician (or other qualified non-physician provider) who is treating the beneficiary are not reasonable and necessary (see Sec. 411.15(k)(1) of this chapter).Article TextThis article contains coding and other guidelines that complement the Local Coverage Determination (LCD) forEEG -Ambulatory Monitoring.Coding Information:Procedure codes may be subject to National Correct Coding Initiative (NCCI) edits or OPPS packaging edits. Refer to NCCI and OPPS requirements prior to billing Medicare.For services requiring a referring/ordering physician, the name and NPI of the referring/ordering physician must be reported on the claim.A claim submitted without a valid ICD-10-CM diagnosis code will be returned to the provider as an incomplete claim under Section 1833(e) of the Social Security Act.The diagnosis code(s) must best describe the patient's condition for which the service was performed. For diagnostic tests, report the result of the test if known; otherwise the symptoms prompting the performance of the test should be reported.Documentation Requirements:The patient's medical record must contain documentation that fully supports the medical necessity for services included within the LCD. (See "Indications and Limitations of Coverage.") This documentation includes, but is not limited to, relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.Monitoring beyond 72 hours must be supported by written documentation for each additional 24 hours of monitoring and be made available to Medicare upon request.Utilization Guidelines:The following represent the number of 24-hour segments of recordings for testing:For diagnostic testing  Two or three days is usually sufficient when looking for seizures or interictal activityFor pre-surgical evaluation  Seven to ten days may be required to capture at least three or four seizures in order to be sure of seizure onset location reliability. Two to three days is usually sufficient for follow-up.
