Children’s Services Handbook : 4 Texas Health Steps (THSteps) Dental : 4.2 Services, Benefits, Limitations, and Prior Authorization : 4.2.27 Orthodontic Services (THSteps)

Orthodontic services are a benefit for THSteps clients who are 13 years of age and older who have either permanent dentition and a severe handicapping malocclusion or one of the following special medical conditions:
A severe handicapping malocclusion is defined by Texas Medicaid as dysfunctional masticatory (chewing) capacity as a result of the existing relationship between the maxillary (upper) and mandibular (lower) dental arches or teeth that without correction will result in damage to the temporomandibular joint (s) (TMJ) or other supporting oral structures (e.g., bone, tissues, intra- or extra-oral muscles, etc.).
Exception to the age restriction may be considered for clients who are 12 years of age and younger if medical necessity has been verified by the dental director for one of the following:
Dental services that are not covered by THSteps Dental Services but are medically necessary and allowable may be a benefit under CCP according to federal Medicaid guidelines and TAC.
As required by the Texas Human Resources Code, if the client is 14 years of age and younger and services are not provided by an exempt entity, THSteps dental providers shall require the client to be accompanied to THSteps dental appointments by a parent, guardian, or other adult who is authorized by the parent or guardian.
Exempt entities (school health clinics, Head Start program, or childcare facilities) that provide services must as a condition of reimbursement:
The following definitions of dentition established by the ADA’s Current Dental Terminology (CDT) manual are recognized by Texas Medicaid:
Transitional Dentition: The final phase of the transition from primary to adult teeth, in which the deciduous molars and canines are in the process of shedding and the permanent successors are emerging.
The American Association of Orthodontists classification of occlusion or malocclusion is as follows:
Class I: A Class I occlusion exists with the teeth in a normal relationship when the mesialbuccal cusp of the maxillary first permanent molar coincides with the buccal groove of the mandibular first molar.
Class II: A Class II malocclusion occurs when the mandibular teeth are distal or behind the normal relationship with the maxillary teeth. This can be due to a deficiency of the lower jaw or an excess of the upper jaw and therefore, presents two types:
Division II exists when the mandibular teeth are behind the upper teeth, with a retrusion of the maxillary front teeth. Both of these malocclusions have a tendency toward a deep bite because of the uncontrolled migration of the lower front teeth upwards.
Class III: A Class III malocclusion occurs when the lower dental arch is in front of (mesial to) the upper dental arch. People with this type of occlusion usually have a strong or protrusive chin, which can be due to either horizontal mandibular excess or horizontal maxillary deficiency. Commonly referred to as an underbite.
