Subluxation of L4/L5 lumbar vertebra, subsequent encounter

This code signifies a partial dislocation or misalignment of the fourth and fifth lumbar vertebrae (L4/L5) in the spine. It indicates that the patient is receiving follow-up care for this specific spinal instability, rather than the initial treatment.

Use this code for patients presenting for ongoing management, physical therapy, or follow-up appointments related to a previously diagnosed L4/L5 subluxation. This includes situations where the patient is recovering from the initial injury or undergoing conservative treatment.

• Ensure documentation clearly specifies "subluxation" and not a complete dislocation.
• Verify the encounter is for subsequent care, not the initial injury or acute treatment.
• Confirm the specific vertebral level (L4/L5) is documented to support this precise code.
