Sprain of ligaments of lumbar spine, subsequent encounter

This code signifies a sprain or tear of the connective tissues (ligaments) supporting the lower back, occurring during a follow-up visit. It indicates that the patient is receiving ongoing care for an injury to the lumbar spine ligaments, rather than presenting for the initial diagnosis.

Apply this code when a patient is seen for continued treatment, rehabilitation, or evaluation of a previously diagnosed lumbar ligament sprain. This includes visits for physical therapy, medication management, or re-assessment of recovery progress after the initial injury.

• Ensure documentation clearly states this is a subsequent encounter for a lumbar ligament sprain.
• Distinguish from initial encounters (A) or sequela (S) encounters.
• Always code with an external cause code if the mechanism of injury is known and relevant.
