Subluxation of T11/T12 thoracic vertebra, initial encounter

This code signifies a partial dislocation or misalignment of the eleventh and twelfth thoracic vertebrae. This condition involves the vertebral bodies or their articulating facets losing their normal anatomical relationship, but remaining in partial contact. It typically results in localized pain, muscle spasms, and potentially neurological symptoms if nerve roots are compressed.

This code is appropriate for the initial encounter of a patient presenting with a diagnosed subluxation of the T11/T12 vertebral segment. This includes cases resulting from trauma, sudden movements, or degenerative changes. It should be used when the patient is receiving active treatment for the injury.

• Ensure documentation clearly specifies "subluxation" and not a complete "dislocation" for this code.
• Verify the specific vertebral level (T11/T12) is documented to support this precise code.
• The "A" seventh character indicates an initial encounter for active treatment; subsequent encounters will require different seventh characters.
