Important note
This Clinical Policy Bulletin expresses Aetna's determination of whether certain services or supplies are medically necessary, experimental and investigational, or cosmetic. Aetna has reached these conclusions based upon a review of currently available clinical information (including clinical outcome studies in the peer-reviewed published medical 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 practicing in relevant clinical areas, and other relevant factors).
Aetna makes no representations and accepts no liability with respect to the content of any external information cited or relied upon in this Bulletin. The discussion, analysis, conclusions and positions reflected in this Bulletin, including any reference to a specific provider, product, process or service by name, trademark, manufacturer, constitute Aetna’s opinion and are made without any intent to defame.
Aetna expressly reserves the right to revise these conclusions as clinical information changes, and welcomes further relevant information including correction of any factual error. CPBs include references to standard HIPAA compliant code sets to assist with search functions and to facilitate billing and payment for covered services. New and revised codes are added to the CPBs as they are updated. When billing, you must use the most appropriate code as of the effective date of the submission. Unlisted, unspecified and nonspecific codes should be avoided.
Each benefit plan defines which services are covered, which are excluded, and which are subject to dollar caps or other limits. Members and their providers will need to consult the member's benefit plan to determine if there are any exclusions or other benefit 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 (for example, will be paid for by Aetna) for a particular member. The member's benefit 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. CMS's Coverage Database can be found on the following website: http://www.cms.hhs.gov/center/coverage.asp.
Policy
We consider 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, treatment is directed toward
- Improving home care
- Reducing plaque/biofilm
- Treating of local factors such as defective restorations
- Reviewing systemic health, including consultation with medical providers to modify medications and /or dental treatment as necessary
- Removing associated calculus buildup (scaling and root planing to remove plaque and calculus from periodontal pockets and to smooth the tooth roots to remove bacterial toxins)
When scaling and root planing of the teeth cannot halt progression of the disease it is necessary to address these defects surgically. This is defined as osseous surgery.
Osseous surgery is a 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.
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 must include the removal of supporting bone (ostectomy) and/or non-supporting bone (osteoplasty).1
Osseous surgery is one of the most common periodontal procedures performed for surgical correction of osseous defects. In addition, if bone defects are severe enough, a bone graft and/or 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.
Since osseous surgery requires a full mucoperiosteal flap and bone removal, the LANAP procedure is not considered osseous surgery. When it meets established clinical guidelines for necessity, LANAP will be benefited at the level of scaling and root planing, D4341/D4342, Periodontal Scaling and Root Planing.1
Refer to CPB #13 -- Bone Replacement Grafts.
