Strain of muscle, fascia and tendon at neck level, init

This code signifies a non-traumatic injury to the muscles, fascia, or tendons in the cervical region, resulting in overstretching or tearing of these soft tissues. It represents an acute, initial presentation of such an injury, often characterized by pain, stiffness, and limited range of motion in the neck.

Use this code for patients presenting with a newly diagnosed neck strain, such as from sudden movements, poor posture, or minor exertion. Documentation should clearly state "neck strain," "cervical muscle strain," or similar, and confirm that this is the first time the patient is being treated for this specific injury.

• Ensure documentation specifies "initial encounter" for this specific injury to justify the "A" seventh character.
• Differentiate from sprains (ligamentous injury) and contusions; this code is exclusively for muscle, fascia, or tendon strain.
• Consider additional codes for external causes (e.g., W00-Y38) if the strain resulted from an accident or injury.
