INSURANCE NARRATIVE FOR SCALING AND ROOT PLANING Re: Treatment Authorization Request — Scaling and Root Planing, Four Quadrants Patient: [Name] Date of Service: [Date] Provider: [Name, License] CDT Codes Submitted: D4341 (SRP—four or more teeth per quadrant), D4342 (SRP—four or more teeth per quadrant) CLINICAL JUSTIFICATION: This patient presents with generalized moderate chronic periodontitis meeting clinical necessity for non-surgical periodontal therapy. Clinical examination and radiographic findings document active periodontal disease warranting four-quadrant scaling and root planing under local anesthesia. CLINICAL FINDINGS: Probing depth measurements reveal generalized pocketing of 4–6 mm on posterior sextants bilaterally with localized pockets of 7 mm at #3 MB, #14 DB, and #30 ML, consistent with advanced attachment loss and active disease. Bleeding on probing is present at 68% of all probing sites, indicating active gingival inflammation and subgingival biofilm colonization. Clinical attachment loss of 3–4 mm is documented in posterior sextants. Generalized moderate subgingival calculus deposits are palpable, with heavy deposits noted on mandibular anteriors. Furcation involvement is classified as Class I at tooth #3 and #30, indicating early furcation disease requiring intervention. Tooth mobility screening is negative, ruling out advanced mobility concerns at this stage. RADIOGRAPHIC EVIDENCE: Full-mouth radiographic series (18 films) taken 03/10/2025 confirms generalized horizontal alveolar bone loss of 15–25% in posterior regions bilaterally. Vertical bone loss is evident at furcation areas of #3 and #30, measured at approximately 3–4 mm apical to expected levels. Interproximal calculus is visible on all posterior teeth, consistent with heavy subgingival deposits. No periapical pathology is identified. These findings support the diagnosis of generalized moderate chronic periodontitis with localized advanced involvement. PREVIOUS TREATMENT HISTORY: Patient last received routine prophylaxis on 01/2024 (14 months prior to current presentation). No prior scaling and root planing is documented. Home care compliance is described as fair; patient reports brushing once daily with occasional flossing. Tobacco history: Former smoker, quit 2 years ago. No active tobacco use at present. CLINICAL NECESSITY: Scaling and root planing is the evidence-based standard of care for generalized moderate chronic periodontitis and is supported by consensus guidelines [verify guideline source: AAP Clinical Practice Guidelines, ADA Standards of Care, or institutional protocol]. The combination of probing depths exceeding 4 mm, 68% bleeding on probing, clinical attachment loss, and radiographic evidence of bone loss constitutes medical necessity for active intervention. Non-surgical mechanical therapy is first-line treatment to disrupt subgingival biofilm, eliminate calculus, and arrest disease progression. Deferral of treatment poses risk of continued attachment loss, further bone resorption, and potential tooth loss. Four-quadrant therapy in a single or staged series is indicated to address the generalized nature of the disease. Post-operative re-evaluation will be scheduled 4–6 weeks following treatment to assess clinical response, determine the need for adjunctive therapy (antimicrobial, laser, or topical agents), or referral for surgical intervention. CDT CODE CORRELATION: D4341 and D4342 (Four or more teeth per quadrant, scaling and root planing, initial/active therapy) are appropriate codes for this comprehensive four-quadrant treatment under local anesthesia targeting subgingival biofilm and calculus removal in a patient with generalized moderate chronic periodontitis.

D4341/D4342 (Scaling and Root Planing — Four or more teeth per quadrant): — Indicates: Probing depths of 4–6 mm, localized 7 mm pockets at #3, #14, #30 meet clinical threshold for SRP (pockets consistently ≥4 mm) — Indicates: Clinical attachment loss of 3–4 mm in posterior sextants — loss exceeding 2–3 mm supports active periodontal therapy — Indicates: Bleeding on probing at 68% of sites demonstrates active subgingival inflammation and biofilm burden — Indicates: Radiographic bone loss of 15–25% and vertical defects at #3, #30 confirm structural periodontal destruction — Indicates: Subgingival calculus deposits confirmed on palpation and radiographs — mechanical removal is therapeutic necessity — Code frequency: Delta Dental PPO allows once per 24 months per quadrant [verify payer policy]; patient has not received SRP in past 14 months, satisfying frequency criteria — Justification: Non-surgical SRP is first-line, evidence-based treatment for generalized moderate chronic periodontitis; medical necessity is established by objective findings

• Probing depths: Generalized 4–6 mm posterior regions, localized 7 mm at #3 MB, #14 DB, #30 ML (exceeds 4 mm threshold for SRP necessity) • Bleeding on probing: 68% of all sites positive (consistent with active disease; normal is <10%) • Clinical attachment loss: 3–4 mm measured in posterior sextants (indicates need for subgingival intervention) • Subgingival calculus: Heavy deposits visible on radiographs and palpable on clinical exam, particularly interproximally • Radiographic bone loss: 15–25% horizontal loss in posterior regions; vertical defects 3–4 mm at #3 and #30 (confirms structural disease progression) • Furcation involvement: Class I at #3 and #30 (early furcation disease requiring non-surgical intervention) • Disease duration and progression: Untreated generalized periodontitis for 14 months since last prophylaxis (increased disease burden and treatment urgency) • Home care status: Fair compliance with brushing once daily and occasional flossing (non-surgical therapy indicated before surgical intervention) • Tobacco history: Former smoker, quit 2 years ago (current non-smoker status — reduced wound-healing complications) • Standard of care: [Verify source] SRP is first-line, evidence-based treatment for Stage II/Grade B generalized moderate chronic periodontitis per ADA/AAP standards
