Final answer:
Skull fractures that are not specified as base fractures should be coded as non-base fractures.
Step-by-step explanation:
All skull fractures, unless specified as base fractures, should be coded as Non-base fractures. There are different types of skull fractures, including linear fractures, comminuted fractures, depressed fractures, and contrecoup fractures. Fractures of the occipital bone at the base of the skull are known as basilar fractures and can be life-threatening, as they can damage the artery that passes through the carotid canal.
