Appeal type: Medical necessity
Decision: Overturned

Diagnosis: anterior crossbite.

Treatment is braces and monthly visits services.

The insurer denied coverage for braces and monthly visits services.

The denial is overturned.

Upon review of the submitted documentation including lateral cephalometric radiograph, panoramic radiograph, montage of extraoral and intraoral clinical images, dental treatment note, three-dimensional representation of study models, as well as insurer correspondence, it appears that this patient presented for evaluation for orthodontic care. The orthodontists identified anterior crossbite (right maxillary lateral incisor) among other findings. The orthodontist has completed the Handicapping Labio-Lingual Deviations (HLD) index as required and has chosen the automatically qualifying condition of crossbite 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 requirements of the HLD index attaining 8 points by internal reviewers when 26 points are required for approval. The patient's mother is appealing on behalf of the patient.

Upon review of the submitted documentation, it is evident that the patient exhibits a significant malocclusion. However, to assess for severity of the malocclusion and therefore medical/dental necessity for orthodontic care, New York State requires, as of September 1, 2012, the use of an orthodontic Index, the Handicapping Labio-Lingual Deviation Index Report (HLD, New York State Medicaid program) 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 as there appears to be gingival recession and attachment loss 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. 

Braces and monthly visits are considered medically necessary for this patient.

Based on the above, the insurer's denial must be overturned. The health care plan did not act reasonably and with sound medical judgment and in the best interest of the patient. The medical necessity for braces and monthly visits services is substantiated.
