Segmental and somatic dysfunction of head region

This code signifies a biomechanical impairment or altered function within the joints, muscles, or connective tissues of the head region. It indicates a disturbance in the normal range of motion, tissue texture, or physiological function, often associated with pain or restricted movement. This dysfunction is not due to a fracture, dislocation, or other specific injury, but rather a functional problem.

Use this code when documentation specifies a diagnosis of segmental or somatic dysfunction affecting the head, such as the temporomandibular joint (TMJ), cranial sutures, or cervical-occipital junction. This is commonly seen in osteopathic manipulative treatment (OMT) or chiropractic care. Supporting documentation should clearly describe the location and nature of the dysfunction.

• Ensure documentation specifies "segmental and somatic dysfunction" and clearly identifies the "head region."
• Do not use this code for specific injuries, inflammatory conditions, or neurological disorders of the head; use more specific codes for those conditions.
• This code is often a primary diagnosis for OMT or chiropractic services, but may also be a secondary diagnosis if another condition is the primary reason for the encounter.
