Subluxation of unspecified thoracic vertebra, init encntr

This code signifies a partial dislocation or misalignment of a thoracic vertebra, where the joint surfaces remain in partial contact. It indicates that the specific thoracic vertebra involved is not documented, and this is the first time the patient is being treated for this condition.

This code is appropriate for initial encounters when a patient presents with symptoms such as back pain, muscle spasms, or limited range of motion in the thoracic spine, and a subluxation is diagnosed but the exact vertebral level is not specified. It is used when the provider's documentation confirms a thoracic subluxation without identifying a specific T-level (e.g., "thoracic subluxation").

• Only use this code when the specific thoracic vertebral level is truly unknown or not documented.
• Ensure the documentation clearly states "initial encounter" for the condition.
• If a specific thoracic vertebra (e.g., T4, T7) is identified, a more specific code from the S23.11-S23.19 series should be used.
