Subluxation of unspecified lumbar vertebra, init encntr

This code signifies a partial dislocation or misalignment of an unknown lumbar vertebra, where the joint surfaces are still in contact but improperly aligned. It indicates the very first time a patient is receiving active treatment for this specific injury.

Apply this code for new injuries involving a subluxation of the lumbar spine when the specific vertebral level (e.g., L1, L2) is not documented. This is appropriate for initial evaluations and treatments of such an injury.

• Ensure documentation clearly states "subluxation" and "lumbar spine" without specifying a vertebral level.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Do not use if the specific lumbar vertebral level is identified; instead, use a more specific code from the S33.11-S33.19 series.
