• D. S06.0X0A, 70250, 70491, 70550

Answer: (A)

In concussion coding, the diagnosis should reflect the initial encounter for the brain injury, and the imaging codes should follow the actual sequence of tests performed. Start with the concussion diagnosis coded as an initial-encounter, unspecified severity, which aligns with a first ED evaluation for a concussion. Then code the imaging in the exact order the studies are done: a skull radiograph to quickly assess for fracture, a head CT to evaluate acute intracranial injury, and finally an MRI of the brain to assess more subtle or occult injury. This creates a clear, stepwise representation of the workup: X-ray of the skull (to screen for fracture), CT of the head (to identify hemorrhage or other acute findings), and MRI of the brain (to evaluate soft tissue and diffuse injuries that CT may miss). The chosen sequence reflects that approach and uses imaging codes that correspond to the specified modalities in the order performed. The other options mix a different initial-encounter code or alter the imaging codes to reflect a different protocol or step order, which would not match the described concussion workup.
