Nondisplaced Type II dens fracture, init for clos fx

This code signifies a fracture of the odontoid process (dens) of the C2 vertebra, specifically a Type II fracture according to the Anderson and D'Alonzo classification. "Nondisplaced" indicates that the bone fragments are in their anatomical alignment, and "closed" means the skin over the fracture is intact.

Apply this code for a patient presenting with a newly diagnosed, nondisplaced Type II dens fracture, where the skin is not broken, and this is the initial encounter for treatment. Documentation should clearly state the fracture type (Type II), lack of displacement, and closed nature, typically confirmed by imaging studies like X-rays or CT scans.

• Ensure documentation specifies "Type II" dens fracture; other types (I or III) have different codes.
• Verify "nondisplaced" and "closed" are explicitly stated or clearly implied by the clinical context.
• The "A" suffix indicates an initial encounter for active treatment; use subsequent encounter codes for follow-up care.
