Number: 012 Subject: Osseous Surgery Date: November 28, 2007 Important Note This Clinical Policy Bulletin expresses Aetna's determination of whether certain services or supplies are medically necessary. We have reached these conclusions based on a review of currently available clinical information (including clinical outcome studies in the peer-reviewed published medical and dental literature, regulatory status of the technology, evidence-based guidelines of public health and health research agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians and dentists practicing in relevant clinical areas, and other relevant factors). We expressly reserve the right to revise these conclusions as clinical information changes, and welcome further relevant information.Each benefits plan defines which services are covered, which are excluded and which are subject to dollar caps or other limits. Members and their dentists will need to consult the member's benefits plan to determine if there are any exclusions or other benefits limitations applicable to this service or supply. The conclusion that a particular service or supply is medically necessary does not constitute a representation or warranty that this service or supply is covered (that is, will be paid for by Aetna) for a particular member. The member's benefits plan determines coverage. Some plans exclude coverage for services or supplies that Aetna considers medically necessary. If there is a discrepancy between this policy and a member's plan of benefits, the benefits plan will govern. In addition, coverage may be mandated by applicable legal requirements of a state, the federal government or CMS for Medicare and Medicaid members. Policy Aetna considers this surgical procedure to be dental-in-nature (DIN) oral surgery. Coverage may be available for DIN oral surgery procedures under either medical or dental plans.Background Periodontal disease is a disease process that negatively affects the alveolar bone that supports the teeth. It is associated with increased clinical probing depths and demonstrated radiographic evidence of horizontal and/or vertical osseous defects. To prevent progression of the disease process, treatment is directed toward improving home care, plaque/biofilm reduction, treatment of local factors such as defective restorations, systemic health review including consultation with medical providers to modify medications and /or dental treatment as necessary and removal of associated calculus buildup (scaling and root planing to remove plaque and calculus from periodontal pockets and to smooth the tooth root to remove bacterial toxins). When scaling and root planing of the teeth cannot halt progression of the disease process, it becomes necessary to address these defects surgically, defined as osseous surgery.Osseous surgery is a minor dentoalveolar surgical procedure that may be necessary for isolated defects of supporting bone or for more generalized regions that involve an entire quadrant. A quadrant is defined as one of the four equal sections into which the dental arches can be divided. It begins at the midline of the arch and extends distally to the last tooth.1 The surgical procedure requires development of a full mucoperiosteal flap reflection of the gingiva (gums), underlying connective tissue and periosteum for access to the osseous defects and root surfaces of teeth. The procedure modifies the bony support of the teeth by reshaping the alveolar process to achieve a more physiologic form. This may include the removal of minor amounts of affected, supporting bone and/or nonsupporting bone. Osseous surgery is one of the most common periodontal procedures performed for surgical correction of osseous defects. In addition, dependent on the severity of the bone defects, a bone graft and membrane may be necessary. The necessity of the surgical procedure/s will be determined by a detailed clinical examination, dental history review, medical history review, oral hygiene review, necessary diagnostic tests, consultations with other health care professionals, and diagnostic procedures such as radiographs and periodontal charting. Refer to CPB #13 -- Bone Replacement Grafts. Codes2 D4260 -- Osseous surgery (including flap entry and closure) -- four or more contiguous teeth or bounded teeth spaces per quadrantD4261 -- Osseous surgery (including flap entry and closure) -- one to three contiguous teeth or bounded teeth spaces per quadrant Revision Dates Original: November 22, 2005Updated: November 28, 2007 Revised: November 20, 2006 The above policy is based on the following references: 1American Dental Association.
