Documentation requirements

Because D4346 sits between prophy and SRP, the chart note has to affirmatively answer two carrier questions: (1) why is this not D1110, and (2) why is this not D4341/D4342. The note that survives audit documents inflammation extent, severity, and the absence of attachment loss / bone loss — all three. A defensible D4346 chart note includes:

• Updated medical history and vitals — RMH reviewed, medications, allergies, ASA status, BP/pulse. Diabetes, smoking, immunosuppression, pregnancy, and certain medications (calcium channel blockers, cyclosporine, anticonvulsants) all influence gingival inflammation and should be noted as risk contributors when present.
• Diagnosis — explicit "generalized moderate gingivitis" or "generalized severe gingivitis" (per the 2017 World Workshop classification of dental plaque-induced gingivitis on an intact periodontium). Phrasing matters: a chart that says only "gingivitis" without "generalized moderate/severe" leaves the carrier to guess whether D1110 or D4346 was the right code.
• Bleeding on probing extent — quantified percentage of sites with BOP, ideally ≥30% to satisfy the ADA "generalized" threshold. If your software produces a BOP score, attach it; if not, document the percentage in the note ("BOP at 38% of sites, generalized; moderate marginal erythema and edema in all six sextants").
• Inflammation severity — moderate vs severe, with descriptors (edema, erythema, spontaneous bleeding, exudate, loss of stippling). A gingival index grade (Loe-Silness GI 2 = moderate, GI 3 = severe) is the cleanest way to document.
• Probing depths — full-mouth probing depths (or at minimum spot probing across all sextants) demonstrating the absence of true periodontal pockets. Pseudo-pocketing from gingival edema (probing 4 mm with no attachment loss) is permitted under D4346; true 4 mm+ pockets with attachment loss push the case into D4341/D4342 territory.
• Clinical attachment level / recession — explicit statement of no CAL or, if recession is present, that recession is not consistent with periodontitis-driven attachment loss. "No clinical attachment loss" or "CAL = 0 mm at all sites probed" is the language carriers want.
• Radiographic interpretation — review of current bitewings and/or PAs, with an explicit statement that there is no radiographic interproximal bone loss (or that bone levels are within 2 mm of the CEJ). If radiographs are not current, note when they were last taken and your clinical reasoning. The 2017 ADA Coding Education guidance treats radiographic confirmation of intact bone as one of the defining features of D4346.
• Calculus burden / extent — supragingival and subgingival calculus deposits, distribution, and tenacity. D4346 implies more deposits than a typical prophy; a chart note describing "light supragingival deposits, no subgingival calculus" reads more like D1110.
• Procedure detail — supragingival and subgingival scaling completed, instrumentation used (ultrasonic, hand instruments, both), areas treated (full mouth), and time spent. Full-mouth scaling for inflammation is a longer appointment than a routine prophy; documenting the time supports the code.
• Patient education / OHI — brushing technique, flossing or interdental aids, plaque-control coaching tied to the patient's specific deposit pattern. Generalized gingivitis is reversible with hygiene; the OHI line is part of the clinical narrative.
• Re-evaluation plan — D4346 is most defensible when followed by a re-evaluation at 4–6 weeks to confirm tissue response. State the plan ("re-evaluate at 4–6 week post-scaling visit; if resolved, transition to D1110 recall; if pockets persist or CAL declares itself, plan SRP") — that language ties the visit to definitive perio diagnosis and demonstrates that D4346 was the correct first step.
• Same-day exclusion check — explicit acknowledgment that D4346 is not being billed alongside D1110, D4341, D4342, or D4355 on the same date. Many EHR templates auto-flag this; documenting it in the note avoids the same-DOS bundling denial.
• Patient tolerance, complications, NV — standard close, plus follow-up timing.

Patterns to avoid in a D4346 chart note: (a) silence on BOP percentage and inflammation distribution — the two most diagnostic data points; (b) "generalized periodontitis" or "deep pockets" anywhere in the note — those phrases support D4341/D4342, not D4346; (c) auto-populated default-normal findings ("WNL" gingiva) that contradict the diagnosis; (d) D4346 billed as a "prophy plus" upgrade for routine recall patients with mild marginal gingivitis — a known audit pattern flagged by Medicaid MCO recoupment programs.

Common denial reasons

The most frequent reasons D4346 is denied, downgraded, or recouped:

• Chart lacks BOP percentage / inflammation extent — the single most common D4346 denial pattern. The ADA descriptor requires "generalized" inflammation, defined by the 2017 ADA Coding Education guidance as ≥30% of sites with moderate-to-severe inflammation. A chart that says only "gingivitis" without quantifying extent is downgraded to D1110.
• Radiographic bone loss visible on submitted images — when bitewings show interproximal bone loss greater than 2 mm from the CEJ, the carrier reads the case as periodontitis and recoups D4346 on the rationale that D4341/D4342 was the appropriate code. Submitting current radiographs with the claim is usually required; submitting radiographs that contradict the code is worse than submitting none.
• CAL or true pockets documented in periodontal chart — clinical attachment loss or probing depths consistent with periodontal pockets push the case into the SRP pathway. D4346 is for inflammation on an intact periodontium.
• D4346 billed on a recall patient with mild gingivitis — the "prophy plus" misuse. Routine recall patients with mild marginal redness should be coded D1110, not D4346.
• Frequency violation — prior D4346 in carrier history — most plans treat D4346 as once-per-lifetime per provider per patient. A second D4346 typically denies; the patient's next visit should be D1110 (resolved) or D4341/D4342 (if perio declares itself).
• Same-day conflict with D1110, D4341, D4342, or D4355 — bundling edits zero-pay D4346 when reported alongside any of these on the same DOS.
• Localized inflammation pattern — a chart describing inflammation in only two sextants does not satisfy "generalized." Carriers reviewing the periodontal chart will recoup D4346 in favor of D1110 + targeted D4342 in the affected sextants.
• No comprehensive or periodic evaluation on file before D4346 — the descriptor specifies "after oral evaluation," and many carriers require an evaluation (D0120/D0150/D0180) on file within a recent window. A D4346 billed with no recent eval triggers manual review.
• Inadequate radiographic imaging — claims submitted without current bitewings (or with bitewings older than the carrier's lookback) are commonly held for documentation. Bitewings should be current within 12–24 months for most carriers.
• Duplicate scaling code on same DOS — billing D4346 on the same date as another scaling code (rare, usually a software error) triggers automatic denial.
• Default-normal templating — chart notes with identical phrasing across patients and no patient-specific BOP %, GI grade, or deposit pattern are flagged as template-fingerprint records on Medicaid MCO audits.
• Pediatric patient under carrier's age threshold — D4346 billed on a patient younger than 13 (or whatever the plan's age floor is) often denies as not a covered benefit at that age.
• Misuse for SRP indications — the most common audit finding. A patient with periodontitis billed as D4346 to avoid the higher patient out-of-pocket of SRP is a recurring fraud-and-abuse pattern that several state Medicaid OIGs have specifically called out.
