  3. A simple appliance on the baby teeth gently opens up that room over months
  4. With more room, the adult tooth comes in on its own path
  5. Once all the adult teeth are through, a second phase of braces may follow

D8060. Phase one treatment while a child has both baby and adult teeth; the common early code.

Interceptive treatment for a young child while baby teeth are still present, used to guide jaw growth or make room so later treatment is shorter. Codes differ by whether the child has only baby teeth or a mix of baby and adult teeth.

Early treatment happens while a child still has baby teeth or a mix of baby and adult teeth, and it aims to guide growth and make room rather than to finish straightening. A second course once all the adult teeth are through is common. The two codes split by which stage of teeth the child is at. Most plans file this as Major. What they actually pay varies by plan.
