Other nondisplaced fracture of second cervical vertebra, initial encounter for closed fracture

📋Clinical Description

This code signifies a fracture of the second cervical vertebra (C2), specifically one that is not displaced and is not further specified as a hangman's or odontoid fracture. It indicates that the patient is receiving initial treatment for this closed fracture.

🎯When to Use

Apply this code when documentation confirms a non-displaced C2 fracture, excluding odontoid or hangman's fractures, and the patient is in the acute phase of treatment. This is typically used for patients presenting to the emergency department or admitted for initial management of the injury.

💡Coding Tips

Ensure documentation specifies "nondisplaced" and "closed fracture" for initial encounter.
Distinguish carefully from odontoid (S12.11-) and hangman's (S12.12-) fractures of C2.
Do not use for subsequent encounters or for open fractures; different seventh characters apply.
