CPT 70450 (Computed tomography, head or brain; without contrast material) is one of the most frequently billed imaging codes in emergency medicine and neurology.
With vs Without Contrast
It is critical to select the correct CT code based on contrast usage:
- 70450: Without contrast.
- 70460: With contrast.
- 70470: Without contrast, followed by contrast and further sections.
Medical Necessity & Trauma
70450 is the gold standard for ruling out intracranial hemorrhage following head trauma. Ensure your ICD-10 codes match the symptoms, such as S06.0X0A (Concussion without loss of consciousness, initial encounter) or R51.9 (Headache, unspecified).
NCCI Edits
If you bill a CTA (CT Angiography) of the head (70496), the standard CT head (70450) is typically bundled into it unless performed at entirely separate, medically necessary encounters.
