D0190 is the CDT code for the screening of a patient — a quick, limited inspection (often in a public-health or triage setting) to determine whether a person needs a full dental evaluation or referral.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D0190 Code
Use D0190 for a screening — a state- or program-specific limited inspection that triages a patient toward an oral evaluation, treatment, or referral. It's commonly seen in public-health programs, school screenings, community events, and intake/triage settings, where the goal is to sort who needs to be seen rather than to perform a full diagnostic exam.
D0190 is distinct from the assessment code, D0191, which is a limited clinical inspection to identify possible signs of disease, malformation, or injury. It is also not an evaluation: a comprehensive exam is D0150, a periodic recall is D0120, and a problem-focused visit is D0140. Using D0190 in place of a true evaluation code is a common error.
Documentation & Clinical Scenarios
Even a brief screening should leave a record:
- The setting and purpose of the screening (program, event, or triage context).
- The screening findings and the resulting recommendation — needs evaluation, needs treatment, or referral.
- The provider or personnel who performed the screening, consistent with state rules.
- Any referral generated and where the patient was directed.
A screening does not include diagnosis or treatment; those services, if performed later, are reported separately under their own codes. The screening note documents the triage decision, not a full workup.
Insurance & Billing Tips
- Know it's often program-based. D0190 is frequently tied to public-health, Medicaid, or community-program reimbursement rather than typical commercial dental benefits.
- Don't bill it as an exam. Submitting D0190 in place of an evaluation code like D0120 or D0150 for a full exam is a coding error.
- Check provider/setting rules. Some payers and states define who may perform and bill a screening and in what context.
- Avoid same-day overlap. D0190 and a full evaluation on the same date for the same encounter are generally not both payable.
- Verify before billing commercial plans. Many commercial plans do not cover D0190; confirm benefits first.
Example Case
At a community health fair, a dental team screens attendees to identify who needs dental care. One attendee shows obvious decay and is told they should see a dentist for a full evaluation; the team records the screening finding and provides a referral. That limited inspection is coded D0190 under the program's reporting rules. When the attendee later books a first appointment at a practice, that visit is evaluated and coded separately — typically as a comprehensive evaluation (D0150) — not as another screening.

Frequently Asked Questions
What's the difference between D0190 and D0191?
D0190 is the screening of a patient — a limited inspection to triage whether a full evaluation is needed — while D0191 is the assessment, a limited clinical inspection to identify possible signs of oral or systemic disease, malformation, or injury and the potential need for referral. The two are closely related and often confused; the distinction lies in the purpose and the descriptor wording, so confirm which your program or payer expects.
Is D0190 the same as a dental exam?
No. D0190 is a brief screening, not a diagnostic evaluation. A full exam is reported with an evaluation code such as D0120 (periodic), D0150 (comprehensive), or D0140 (problem-focused). The screening only triages whether the patient should be seen for an evaluation or referred; billing it as a substitute for an actual exam is a common coding error.
Will commercial insurance cover D0190?
Often not. D0190 is most commonly reimbursed through public-health, Medicaid, or community-program arrangements rather than standard commercial dental benefits, and coverage and eligible settings vary widely by payer and state. Verifying benefits and the specific program rules before billing — and confirming who is permitted to perform and report the screening — helps avoid denials.
Can D0190 and an evaluation be billed on the same day?
Generally no. A screening and a full evaluation for the same encounter are usually not both payable, since the screening is meant to determine whether an evaluation is needed rather than to accompany one. If a patient is screened and then receives a full exam at a later visit, those are separate encounters and are reported separately under their own codes.
