  • Use Q18.0 for Sinus, fistula and cyst of branchial cleft - BILLABLE CODE

  • Use Q18.1 for Preauricular sinus and cyst - BILLABLE CODE

  • Use Q18.2 for Other branchial cleft malformations - BILLABLE CODE

  • Use Q18.3 for Webbing of neck - BILLABLE CODE

  • Use Q18.4 for Macrostomia - BILLABLE CODE

  • Use Q18.5 for Microstomia - BILLABLE CODE

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • cleft lip and cleft palate Q35 Q37
  • conditions classified to Q67.0 Q67.4
  • congenital malformations of skull and face bones Q75
  • cyclopia Q87.0

Patient Education


Craniofacial Abnormalities

Craniofacial is a medical term that relates to the bones of the skull and face. Craniofacial abnormalities are birth defects of the face or head. Some, like cleft lip and palate, are among the most common of all birth defects. Others are very rare. Most of them affect how a person's face or head looks. These conditions may also affect other parts of the body.

Treatment depends on the type of problem. Plastic and reconstructive surgery may help the person's appearance.

Neck Injuries and Disorders

Any part of your neck - muscles, bones, joints, tendons, ligaments, or nerves - can cause neck problems. Neck pain is very common. Pain may also come from your shoulder, jaw, head, or upper arms.

Muscle strain or tension often causes neck pain. The problem is usually overuse, such as from sitting at a computer for too long. Sometimes you can strain your neck muscles from sleeping in an awkward position or overdoing it during exercise. Falls or accidents, including car accidents, are another common cause of neck pain. Whiplash, a soft tissue injury to the neck, is also called neck sprain or strain.

Treatment depends on the cause, but may include applying ice, taking pain relievers, getting physical therapy or wearing a cervical collar. You rarely need surgery.
