Diagnosis: Anterior cross bite.

Treatment: Braces.

The insurer denied coverage for braces.

The denial is overturned.

Upon review of the submitted documentation including lateral cephalometric radio graph, panoramic radio graph, montage of extraoral and intraoral clinical images, as well as insurer correspondence, it appears that this patient presented for orthodontic care. The orthodontist recommended comprehensive orthodontics due to anterior crossbite with gingival attachment loss (teeth #10 (lateral incisor upper left) and #23 (lateral incisor)) in addition to other clinical findings. The orthodontist has completed the HLD (Handicapping Labio-Lingual Deviation Index) Report index as required and has chosen the automatically qualifying condition of cross bite of individual anterior teeth when clinical attachment loss and recession of the gingival margin are present. The insurer has denied coverage for orthodontic treatment as not medically necessary as the clinical circumstance does not meet the required handicapping malocclusion medical necessity requirements attaining a score of 6 points on the HLD index where 26 points is required.

Upon review of the submitted documentation, (study models were not provided for review), it is evident that the patient exhibits a malocclusion. However, to assess for severity of the malocclusion and therefore medical/dental necessity for orthodontic care, New York State requires the use of an orthodontic Index, the Handicapping Labio-Lingual Deviation Index Report (HLD, New York State Medicaid program1) modeled after Handicapping Labiolingual Deviation Index. This index provides six specific conditions that automatically qualify for orthodontic care. Additional criteria are used utilizing a point system if none of these initial qualifying conditions are met or selected. For these other secondary criteria to qualify for orthodontic care a total score of 26 points is necessary.

In this case, the treating orthodontist claims an automatic qualifying condition of crossbite of individual anterior teeth when clinical attachment loss and recession of the gingival margin are present. This reviewer finds that this automatically qualifying condition criterion is met and does support comprehensive orthodontic care. In this case, the clinical circumstance does meet insurer and plan criteria to justify orthodontic care.

Regarding the validity of the Handicapping Labiolingual Index, it has been shown through scientific scrutiny in peer reviewed journals that this methodology for assessing orthodontic need is a valid approach. Each of these peer reviewed articles concludes that this index is a valid and reliable determinant of need for orthodontic care. As this is an accepted methodology, this has been determined to represent an appropriate approach for assessing orthodontic need.


The health plan did not act reasonably with sound medical judgment in the best interest of the patient.

The insurer's denial of coverage for the insertion of braces is overturned. Medical Necessity is substantiated.
