Clinical Coverage Criteria

Medical necessity indication

Scaling and root planing is eligible for benefit-payment consideration when all required clinical findings are present for each involved tooth.

Primary clinical indication

Required findings
- Radiographic bone loss: Radiographic evidence of alveolar bone loss on the involved tooth.
- Attachment loss: Interdental clinical periodontal attachment loss.at least 1-2 mm
- Probing depth: Periodontal probing depth.4 mm or greater

Code and quadrant criteria

The submitted code and quadrant must correspond to the number of qualifying teeth.

Code selection by qualifying teeth

D4341: Periodontal scaling and root planing for four or more qualifying teeth in the same quadrant.4 or more teeth per quadrant
D4342: Periodontal scaling and root planing for one to three qualifying teeth in the same quadrant.1-3 teeth per quadrant

General quadrant criteria

For quadrant-based periodontal procedures, the treatment must address a clinically appropriate periodontal condition.

Quadrant treatment criteria

Abnormal pocket depths: Periodontal charting indicates abnormal pocket depths at multiple sites.
Radiographic support
- Root calculus: Radiographic evidence of root-surface calculus.
- Bone support loss: Radiographic evidence of noticeable loss of bone support.

Not medically necessary or clinically inappropriate conditions

The following conditions generally support disapproval as not medically necessary or not clinically appropriate.

Inappropriate indications or deficient treatment

Gingivitis without attachment loss: Gingivitis without loss of attachment.
Calculus without attachment loss: Supragingival and subgingival calculus without loss of attachment.
Non-periodontal attachment loss: Loss of attachment due to vertical root fracture, dental caries, extraction or malposition of teeth, or draining endodontic lesions.
Advanced disease monotherapy: Scaling and root planing used as monotherapy for severe or advanced periodontitis.

More than two quadrants in one appointment

More than two quadrants on the same date requires additional justification.

Single-appointment treatment beyond two quadrants

Medical necessity: Credible evidence supports single-appointment, full-mouth therapy based on the patient's condition.
Pain control: Adequate pain control is provided.
Treatment time: Adequate time is spent to provide therapeutically effective treatment for all involved quadrants.

Repeat treatment

Repeat or site-specific scaling and root planing may be considered when progression is documented.

Retreatment or site-specific repetition

Progression findings
- Attachment instability: Lack of stability of clinical attachment.
- Persistent inflammation: Unresolved gingival tissue inflammation.
- Increasing probing depths.
- Elevated plaque levels: Plaque levels inconsistent with periodontal tissue health.

Scaling and root planing is generally not eligible for benefit payment when the condition is gingivitis without attachment loss or supragingival or subgingival calculus without attachment loss. Disapproval may also apply when attachment loss results from non-periodontal causes, including vertical root fracture, dental caries, extraction or malposition of teeth, or a draining endodontic lesion. Other exclusions include scaling and root planing used as monotherapy for severe or advanced periodontitis, treatment of teeth with a hopeless periodontal, endodontic, or structural prognosis, incomplete or inadequate treatment, failure to treat all teeth requiring periodontal care, and inadequate or incorrect documentation.

No payment is made when scaling and root planing is performed in conjunction with oral prophylaxis, gingivectomy, or gingivoplasty.

Scaling and root planing is generally not medically necessary or clinically appropriate for gingivitis or calculus without attachment loss. These conditions do not establish the periodontal disease-related attachment loss required to support therapeutic nonsurgical periodontal treatment.

Authorization and Documentation Requirements

Prior Authorization

Prior Authorization Required

Obtain prior authorization when required before performing or submitting scaling and root planing. Submit the required clinical and radiographic documentation with the request.

Current radiographs and a completed Evaluation Form to Scaling and Root Planing.
Complete periodontal charting with AAP Case Type.
Periodontal treatment plan and periodontal history.

Documentation Required

Preoperative Periodontal Charting

Document preoperative six-point periodontal charting performed within 12 months of treatment, including clinical attachment loss and other relevant periodontal findings.

Chart all six surfaces for each involved tooth.

Procedure Background

Scaling and root planing is a therapeutic, nonsurgical periodontal procedure, not a preventive oral prophylaxis. It removes supragingival and subgingival plaque and calculus and smooths contaminated root surfaces. The procedure may serve as definitive treatment for earlier periodontitis or as a presurgical treatment for more advanced disease; local anesthesia is commonly needed.

Procedure Definitions

Scaling and root planing

Supragingival instrumentationInstrumentation of crown surfaces to remove microbial plaque and calculus

Subgingival instrumentationInstrumentation of root surfaces to remove microbial plaque and calculus

Root planingSmoothing dentin and cementum and removing contamination from toxins and microorganisms

Closed subgingival scaling and root planing

Procedure approachPerformed without direct vision

Diagnostic basisPreoperative radiographs and documented comprehensive periodontal examination findings

Radiographic crestal bone

Minimum crestal boneAt least 3 mm

Required radiographCurrent bitewing radiographs

PurposeRequired for prior authorization

Radiograph timing

Preoperative periodontal chartingPerformed within 12 months of treatment

Isolated-tooth periapical radiographsCurrent radiographs dated within 6 months of the prior-authorization request

Radiographic requirementsRadiographs must be diagnostic quality, properly angulated, and demonstrate root-surface calculus or periodontal bone loss where applicable.

Scaling and root planing may be denied when the required periodontal attachment loss and supporting clinical findings are not demonstrated for each involved tooth.

Document radiographic alveolar bone loss on each involved tooth.
Document interdental clinical periodontal attachment loss of at least 1–2 mm on each involved tooth.
Document periodontal probing depths of 4 mm or greater on each involved tooth.

Billing Rule

Correct Code for Qualifying Teeth

Use the procedure code that matches the number of qualifying teeth in the quadrant. Incorrect coding may result in disapproval for benefit payment.

D4341: four or more qualifying teeth in the same quadrant.
D4342: one to three qualifying teeth in the same quadrant.
Do not submit D4341 when only one to three teeth in the quadrant qualify; submit D4342 instead.

Denial Risk

Clinically Inappropriate Treatment

Avoid scaling and root planing when the condition or treatment does not establish medically necessary periodontal therapy or is clinically deficient.

Gingivitis, calculus without attachment loss, or attachment loss from non-periodontal causes such as fractures, caries, extraction or malposition, or draining endodontic lesions.
Scaling and root planing as monotherapy for severe or advanced periodontitis.
Hopeless periodontal, endodontic, or structural prognosis; incomplete treatment of previously treated teeth; or failure to treat teeth requiring therapy.
Inadequate or incorrect documentation may support denial.

Denial Risk

More Than Two Quadrants on One Date

More than two quadrants of scaling and root planing on the same date of service is generally not clinically appropriate unless the record credibly supports single-appointment full-mouth therapy.

Document medical necessity based on the patient's condition.
Document adequate pain control.
Document sufficient time to provide therapeutically effective treatment for every quadrant treated.

Denial Risk

Pain-Control and Treatment Documentation

Claims may be denied or scrutinized when anesthesia and the extent and quality of treatment are not adequately documented. Local anesthesia is generally expected for properly performed scaling and root planing.

Document the anesthetic used and the patient's pain control.
Document adequate treatment time and the procedures completed for all quadrants involved.
Consistent performance without anesthetic documentation may prompt review for inadequate thoroughness.

Denial Risk

Missing Clinical Documentation

Submit complete clinical documentation supporting medical necessity and clinical appropriateness. If required information cannot be provided, benefit payment may be disapproved.

Preoperative six-point charting within 12 months, including attachment loss and relevant findings.
Diagnostic-quality full-mouth radiographs with bitewings and applicable isolated-tooth periapicals.
AAP diagnosis, prognosis, treatment plan, periodontal history, and relevant risk factors.
Delta Dental of Ohio may request additional clinical information needed to make a coverage decision.
