Appeal type: Medical necessity
Decision: Upheld

Diagnosis: Skeletal class II, Class II canines, retruded mandible, excessive overjet, maxillary and mandibular spacing, and deep impinging overbite

Treatment: D8080 braces and D8670 orthodontic visits

The insurer denied coverage for D8080 braces and D8670 orthodontic visits.

The denial is upheld.

Upon review of the submitted documentation including lateral cephalometric radiograph, panoramic radiograph, montage of extraoral and intraoral clinical images, treatment records, as well as insurer correspondence, it appears that this patient presented for evaluation for orthodontic care.  The Orthodontist recommended comprehensive orthodontics due to skeletal class II, Class II canines, retruded mandible, excessive overjet, maxillary and mandibular spacing, and deep impinging overbite.  The Orthodontist has completed the Handicapping labio-lingual (HLD) index as required and has chosen the automatically qualifying condition of deep impinging overbite with severe soft tissue damage to support orthodontic necessity.  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 on the HLD index attaining 14 points on review by internal reviewers.  

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, a Handicapping Labiolingual Deviation Index (HLD) is utilized.  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 deep impinging overbite with severe soft tissue damage.  This reviewer finds that this automatically qualifying condition criterion is not met as there is no evidence of soft tissue damage, and does not support comprehensive orthodontic care.  This reviewer concurs with the HLD index of the insurer attaining 14 points (8 points overjet, 5 points overbite, and 1 point labiolingual spread.

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.  This is confirmed by several studies. 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 healthcare plan acted reasonably and with sound medical judgment in the best interest of the patient. D8080 braces and D8670 orthodontic visits are not considered medically necessary for this patient.
The insurer's denial of coverage for D8080 braces and D8670 orthodontic visits is upheld. Medical Necessity is not substantiated.
