Strain of muscle, fascia and tendon of lower back, init

This code signifies an injury to the soft tissues of the lower back, specifically involving the muscles, fascia, or tendons, resulting from overstretching or tearing. It indicates the initial presentation or active treatment phase of such an injury.

Apply this code for patients presenting with acute low back pain following an event like heavy lifting, sudden twisting, or a fall, where a strain of the musculature or connective tissue is diagnosed. This is appropriate for the first encounter for this specific injury.

• Ensure documentation clearly specifies the lower back as the affected anatomical region.
• Confirm the encounter is for the initial treatment of the strain, not a follow-up or sequela.
• Distinguish from sprains (ligamentous injury) or other types of back pain.
