Dislocation of L4/L5 lumbar vertebra, initial encounter

This code signifies a complete displacement of the fourth lumbar vertebra from the fifth lumbar vertebra, specifically referring to the initial treatment for this injury. This type of spinal injury can result in significant pain, neurological deficits, and instability of the lower back.

This code is appropriate for documenting the initial encounter for a patient presenting with a newly diagnosed dislocation between the L4 and L5 vertebrae. This includes situations where the patient is undergoing initial evaluation, treatment, or surgical intervention for this specific injury.

• Ensure documentation clearly specifies the L4/L5 level of dislocation.
• Verify this is the patient's first time receiving active treatment for this particular injury to use the "A" (initial encounter) seventh character.
• Always code any associated neurological deficits or other injuries separately.
