SDF Dental Code (D1354): Silver Diamine Fluoride Billing

What D1354 covers

D1354 reports the topical application of a caries-arresting medicament to a tooth that has an active, non-symptomatic carious lesion. The medicament is painted onto the lesion to stop or slow the decay, without drilling out tooth structure and without placing a restoration. The most common medicament is silver diamine fluoride (SDF), though the code is written around the clinical action, not the specific product.

Two things define the code: purpose and scope. The purpose is arrest. There is an existing, active cavity, and the medicament halts it. The scope is one tooth. D1354 is reported per tooth, so a visit where several teeth are treated produces several units of D1354.

The code is for the medicament application itself. The exam that found the decay, any radiographs, and any restoration placed later are separate procedures with their own codes.

What D1354 is not

• A caries-preventive medicament (D1355). This is the most common miscode. D1355 is preventive, applied to a sound surface for primary prevention or remineralization. D1354 treats decay that already exists. Same product can be involved. The intent on the tooth is what separates them.
• A topical fluoride treatment. D1206 (fluoride varnish) and D1208 (other topical fluoride, excluding varnish) are whole-mouth preventive applications reported once per visit. They are not per-tooth lesion treatments. SDF applied to arrest a specific cavity is D1354, not a fluoride code, even though SDF contains fluoride.
• A definitive restoration. SDF arrests the lesion. It does not fill or rebuild the tooth. If a restoration is placed, that restoration has its own code. The “interim” in the code name is the tell: it is a holding measure, not the final fix.
• Enamel regeneration (D2991). D2991 reports a scaffold-based application that guides hydroxyapatite regeneration on an early lesion. It is classified as restorative, and it is a different clinical action than arresting an active cavity in place.

D1354 vs. D1355: the distinction that drives the code

This is where the code gets miscoded, so be precise. D1354 and D1355 are both per-tooth medicament codes, both can use SDF, and the products can be physically identical. They do not overlap in clinical intent, and the code follows the intent.

D1354 is for arrest. There is an active carious lesion on the tooth, and the medicament is applied to stop it from progressing. D1355 is for prevention. The surface is sound or at risk, and the medicament is applied to prevent decay or support remineralization in a high-caries-risk patient. One treats a cavity that already exists. The other protects a tooth before a cavity forms.

Per tooth, not per visit

D1354 is reported per tooth. Each tooth treated is its own unit, tied to its own tooth number and its own chart entry.

This trips up offices that are used to the topical fluoride codes, which work the opposite way. D1206 and D1208 are reported once per visit no matter how many teeth get coated, because they are whole-mouth applications. D1354 is a lesion-specific treatment, so the unit is the tooth.

The practical consequences:

• A visit where SDF is applied to four active lesions on four teeth supports four units of D1354, each documented separately, not one line for the visit.
• Posting a single D1354 for a multi-tooth SDF appointment underbills the work that was actually done.
• Each unit needs its own tooth number on the claim and a chart note that names the lesion on that tooth. A claim with one tooth number and a quantity of four, or four lines with no per-tooth findings, is harder to defend on review.

Coverage reality: Medicaid-first, commercial uneven

SDF coverage grew out of public health programs, and the coverage map still reflects that.

• Medicaid and CHIP. Many state Medicaid and CHIP programs cover D1354. A common structure is a per-tooth lifetime cap (two applications per tooth shows up frequently) and sometimes an age limit. The exact rules are set state by state, so the program’s own policy is what governs.
• Commercial plans. Coverage is uneven. Some commercial plans cover D1354 as a preventive benefit, some cover it only for children, some apply frequency or age limits, and some exclude it. There is no single commercial-market rule to assume.
• Patient-pay. When a plan excludes D1354, it is usually a low-cost procedure relative to a restoration, which is part of why patients accept it. But low fee does not mean charge-by-default: on participating Medicaid plans, confirm the patient-billable rules before charging, because balance-billing limits may apply.

When to bill D1354

Bill D1354 when a caries-arresting medicament, usually SDF, is applied to a tooth with an active, non-symptomatic carious lesion to stop the decay without restoring the tooth. Common situations:

• A pediatric patient with active decay who cannot yet tolerate, or whose family wants to defer, conventional restorative treatment.
• A geriatric or special-needs patient where drilling and restoration are difficult, and arresting the lesion is the practical goal.
• An active lesion the office is stabilizing while the patient waits for a restorative appointment.
• Root-surface or other lesions on patients at high risk where arrest is the clinical plan.

Do not bill D1354 for:

• A preventive application to a sound or at-risk surface. That is D1355.
• A whole-mouth fluoride treatment for prevention. That is D1206 or D1208.
• The restoration that later fills the tooth. That has its own code.
• A symptomatic tooth being treated for pain or infection. D1354 is scoped to non-symptomatic lesions. Symptomatic teeth point toward different diagnostic and treatment codes.

Documentation that supports the claim

The per-tooth, lesion-specific nature of D1354 makes documentation the difference between a clean claim and a denied one. For each tooth treated, the note should capture:

• The tooth and the lesion. Tooth number and the active carious lesion on it, including surface and a brief description. This is the line that distinguishes D1354 (active decay) from D1355 (sound surface).
• The medicament. That a caries-arresting medicament was applied, and which one (silver diamine fluoride is the usual answer).
• The clinical intent. That the purpose was to arrest the lesion, not to restore the tooth and not to prevent decay on a sound surface.
• The interim nature. Whether a restoration is planned later, monitoring is planned, or arrest is the endpoint for that tooth. The “interim” framing is built into the code.
• Patient or guardian acknowledgment of staining. SDF darkens the arrested lesion. Noting that the patient or guardian was informed and consented protects the office from a later “no one told me it would turn black” complaint. This is a clinical and patient-relations note more than a billing one, but it belongs in the record.

A one-line narrative on the claim, naming the tooth and the active lesion arrested with SDF, helps a carrier process it against the right benefit and against the per-tooth frequency edit.

What to get right in your PMS

The exact menus differ across Open Dental, Dentrix, Eaglesoft, Curve, and Carestream, but the setup that prevents problems is the same:

1. Keep D1354 and D1355 as distinct, clearly labeled codes. The fastest way to miscode is a single fuzzy “SDF” entry. Label one as arresting (D1354) and one as preventive (D1355) so whoever posts the visit picks the one that matches the lesion status, not the product.
2. Post D1354 per tooth, with the tooth number on every unit. Configure it so the system prompts for a tooth number and so a multi-tooth visit posts multiple units, not one. This is the opposite of how D1206 and D1208 are posted.
3. Track per-tooth frequency. Because the common Medicaid cap is per tooth (often two per tooth), the record needs to show how many times each tooth has been treated, not just a patient-level count. That is what tells the front desk a specific tooth has hit its limit.
4. Verify coverage, caps, and age limits before treatment. SDF coverage and its limits vary widely by plan and by state Medicaid program. Verify the specific plan, and do not carry one state’s Medicaid rules over to another.
5. Confirm patient-billable rules on participating plans. On Medicaid and other participating contracts, check whether the fee is patient-billable before charging when the plan does not pay. A low fee is not a reason to skip the participating-provider check.
