Dislocation of C7/T1 cervical vertebrae, initial encounter

This code signifies a complete displacement of the C7 vertebra from the T1 vertebra, indicating a loss of normal anatomical alignment at this specific cervicothoracic junction. This injury can involve damage to ligaments, joint capsules, and potentially the spinal cord.

Apply this code for a patient presenting with a newly diagnosed dislocation between the seventh cervical and first thoracic vertebrae. Documentation must clearly state "dislocation" and specify the C7/T1 level, along with an indication that this is the initial treatment encounter for the injury.

• Ensure documentation specifies "dislocation" versus "subluxation" (S13.19XA for unspecified cervical dislocation).
• Verify the specific vertebral level is C7/T1; other cervical dislocations have different codes.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
