Subluxation of T8/T9 thoracic vertebra, subsequent encounter

This diagnosis code indicates a partial dislocation or misalignment of the eighth and ninth thoracic vertebrae (T8 and T9) that is being addressed during a subsequent visit. This condition can result in localized pain, muscle spasms, and restricted range of motion in the mid-back region. It signifies that the initial treatment or evaluation for this subluxation has already occurred.

This code is appropriate for follow-up appointments where a patient is receiving ongoing care for a previously diagnosed T8/T9 thoracic subluxation. This includes visits for physical therapy, chiropractic adjustments, medication management, or re-evaluation of symptoms after the initial injury or diagnosis. It should be used when the patient is no longer in the acute phase of treatment.

• Ensure documentation clearly states "subsequent encounter" or indicates ongoing treatment for the subluxation.
• Verify the specific vertebral levels (T8/T9) are documented to support this precise code.
• Do not use for initial encounters or for sequelae (late effects) of the subluxation.
