Subluxation of C3/C4 cervical vertebrae, subs encntr

This code signifies a partial dislocation or misalignment of the C3 and C4 vertebrae in the neck, specifically when the patient is receiving follow-up care for this injury. This condition can lead to neck pain, stiffness, and neurological symptoms if nerve roots are compressed.

Apply this code for patients presenting for ongoing treatment, such as physical therapy, chiropractic adjustments, or follow-up imaging, for a previously diagnosed C3/C4 subluxation. Documentation should clearly indicate the encounter is not for the initial injury but for subsequent management.

• Ensure documentation specifies "subluxation" and not a complete "dislocation" (which would be a different code series).
• Verify the specific vertebral levels (C3/C4) are clearly documented.
• The "D" seventh character indicates a subsequent encounter; do not use for initial treatment or sequelae.
