Subluxation of L2/L3 lumbar vertebra, subsequent encounter

This code signifies a partial dislocation or misalignment of the second and third lumbar vertebrae (L2/L3) that is being addressed during a follow-up visit. The subluxation indicates that the joint surfaces are still in partial contact, differentiating it from a complete dislocation. This condition can lead to localized pain, muscle spasms, and restricted range of motion in the lower back.

Use this code for encounters where a patient is receiving ongoing treatment, follow-up care, or rehabilitation for a previously diagnosed subluxation of the L2/L3 lumbar vertebra. This includes visits for physical therapy, chiropractic adjustments, medication management, or re-evaluation after the initial injury. It is appropriate when the patient is no longer in the acute phase of injury.

• Ensure documentation clearly specifies "subluxation" and not "dislocation" for L2/L3.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always confirm the specific vertebral level (L2/L3) is documented to support this precise code.
