This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
Billing and coding for immunizations must follow the coverage indications, limitations, and medical necessity criteria set forth in the associated Local Coverage Determination LCD L34596 (Immunizations).
Medical records must include history and physical notes, laboratory results, and documentation of signs and symptoms that warrant the head/neck diagnostic imaging.
Accurate HCPCS/CPT coding must be submitted to differentiate CT and MRI scans from other radiology services and to support coverage determinations.

CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
Preventive immunizations are covered for pneumococcal, hepatitis B, and influenza vaccines.
When the patient has not been previously immunized for rabies, coverage includes RIG (half IM and half wound on day 0) plus HDCV on days 0, 3, 7, 14, and 28.
Vaccinations are covered only when directly related to treatment of an injury or direct exposure to a disease/condition listed in this policy.
Tdap or Td vaccines are covered when given for an acute injury in a person who is incompletely immunized for tetanus.
