Provider Actions & Documentation Requirements

Documentation Required

Document indication and donor-site suitability

Document the specific clinical indication for the graft and, for autogenous grafts, document donor-site suitability. Indications to note include unresolved sensitivity in areas of recession, progressive recession or chronic inflammation, and areas with less than 2 mm of attached gingiva. For autogenous grafts, document that the palatal donor site is suitable (not broad/shallow) and does not have excessively glandular or fatty submucosal tissue or roots covered with thin bony plates.

Unresolved sensitivity in areas of recession
Progressive recession or chronic inflammation
Areas with less than 2 mm of attached gingiva
Donor-site suitability: not a broad, shallow palatal donor site
Donor-site suitability: not excessively glandular or fatty submucosal tissue
Donor-site suitability: no roots covered with thin bony plates

Documentation Required

Document contraindications/medical status

Document patient medical conditions and current medications that may impair healing and ensure these conditions are addressed or managed prior to surgery. Examples of medications and conditions to record include immunosuppressive agents, corticosteroids, anticoagulants, NSAIDs, and nicotine use, as well as unmanaged medical conditions (metabolic, cardiovascular, autoimmune/inflammatory, or genetic conditions that affect collagen synthesis).

Medications: immunosuppressants, corticosteroids, anticoagulants, NSAIDs, nicotine
Medical conditions: unmanaged metabolic, cardiovascular, autoimmune/inflammatory, or genetic conditions affecting collagen synthesis

Billing Rule

Use listed CDT codes

Report the applicable CDT procedure codes when submitting claims. The listed CDT codes are provided for reference only; inclusion in this policy does not guarantee coverage or payment — the member-specific benefit plan governs coverage determinations.

Clinical Background, Evidence, and Definitions

Background: Mucogingival conditions are deviations from the normal anatomic relationship between the gingival margin and the mucogingival junction. Surgical grafting procedures are described as the gold standard to correct localized gingival defects and provide a functionally adequate zone of attached gingiva.

Factors affecting success: Success of these procedures is highly dependent on individual patient considerations such as level of oral hygiene, smoking status, and overall health. The policy also notes situations where procedures may not be indicated (for example unmanaged medical conditions, medications that impair healing) and specific donor‑site limitations for autogenous grafts.

Evidence — Cochrane review (2018): The Cochrane systematic review evaluated 48 randomized controlled trials and found that subepithelial connective tissue grafts plus coronally advanced flap showed greater reduction in gingival recession versus guided tissue regeneration with resorbable membranes plus CAF; overall risk of bias and evidence quality were variable.

Evidence — Zucchelli et al. (2014): A randomized trial of CAF versus CAF + CTG for multiple adjacent recessions showed no significant difference at 6 months and 1 year, but at 5 years the CAF + CTG group demonstrated statistically greater recession reduction, higher probability of complete root coverage, greater increase in buccal keratinized tissue height, and better contour evaluation.

Evidence — Kuis et al. (2013): A 5‑year split‑mouth randomized trial comparing CAF alone versus CAF + CTG for single defects found both procedures effective, but CAF + CTG provided significantly better results across evaluated clinical parameters and better long‑term outcomes (60 months) than CAF alone.

Term	Definition
Autogenous Graft	Tissue taken from one site of a patient's body and transferred to another site of the same patient.
Graft	A piece of living tissue placed in contact with injured tissue to repair a defect or supply deficiency; tissue used for implantation or transplantation; to induce union between normally separate tissues.
Recession	Migration of the marginal soft tissue to a point apical to the cemento-enamel junction or implant platform; includes Miller Class I-IV descriptions.
