Other disp fx of fourth cervical vertebra, sequela

This code indicates a long-term complication or late effect stemming from a previously sustained displaced fracture of the fourth cervical vertebra. It signifies that the initial injury has healed, but residual issues directly attributable to that fracture are now being addressed. This could include chronic pain, nerve damage, or functional limitations.

Use this code when documenting a patient encounter for a condition that is a direct consequence of a healed, displaced C4 vertebral fracture. The medical record should clearly link the current symptoms or condition to the past fracture. This code is appropriate for follow-up care addressing chronic issues, not for the initial acute injury or its immediate healing phase.

• Requires a seventh character "S" to indicate sequela, meaning the initial injury has healed and the current condition is a late effect.
• Do not use for initial or subsequent encounters for the acute fracture; those require different seventh characters (A, B, D, G, K, P).
• Always code the specific sequela (e.g., chronic pain, myelopathy) first, followed by this code to indicate the etiology.
