Sprain of thyroid region

This code describes a sprain or strain injury affecting the soft tissues, ligaments, or muscles in the region of the thyroid gland. This typically involves the anterior neck structures, such as the sternocleidomastoid muscle or associated cervical ligaments, without evidence of fracture or dislocation.

Use this code for patients presenting with pain, tenderness, or limited range of motion in the anterior neck following trauma, where clinical assessment indicates a sprain or strain in the thyroid region. Documentation should clearly specify a sprain or strain and localize the injury to the neck area overlying the thyroid.

• Differentiate from cervical spine sprains (847.x) which involve the bony vertebral structures.
• Ensure documentation specifies "sprain" or "strain" and not just "neck pain" to support this code.
• Consider an E-code to identify the cause of the injury if known (e.g., fall, motor vehicle accident).
