D9450 is the CDT code for a case presentation involving detailed and extensive treatment planning. It reports the dedicated time a dentist spends developing and presenting a complex, multi-step treatment plan to a patient — the kind of in-depth planning that goes well beyond the discussion folded into a routine exam.
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 D9450 Code
Report D9450 when the dentist provides a detailed and extensive treatment-planning case presentation — typically for a patient facing complex restorative, periodontal, implant, or full-mouth rehabilitation work that requires significant planning and explanation. It reflects substantial, dedicated planning effort, not the brief treatment talk that accompanies a standard evaluation.
The descriptor specifies that this is for an established patient and is generally not performed on the same day as an evaluation. Don't confuse D9450 with the evaluation codes (D0150 comprehensive, D0120 periodic) — those include their own routine treatment-planning discussion. D9450 is reserved for the distinct, extensive planning session that a complex case demands.
Documentation & Clinical Scenarios
Because D9450 represents dedicated planning time, the record must show the complexity and the separate effort involved:
- The scope and complexity of the case that justified extensive planning — multiple phases, several disciplines, or full-mouth work.
- That it was a distinct case-presentation session, generally on a different day than the evaluation.
- The treatment plan presented, including the options and sequencing discussed with the patient.
- A narrative, since payers closely scrutinize planning-time charges.
D9450 reports the planning and presentation. The evaluations, imaging, diagnostic models, and eventual treatment are each documented and coded separately.
Insurance & Billing Tips
- Verify coverage. Many plans reimburse case-presentation/planning charges inconsistently or not at all, viewing planning as part of the evaluation.
- Keep it off the evaluation day. The descriptor indicates D9450 is generally not performed on the same date as an evaluation; same-day billing often triggers a denial.
- Document the complexity. A narrative establishing why extensive planning was needed supports the claim.
- Don't duplicate the exam discussion. Routine treatment talk is included in evaluation codes; D9450 must reflect distinct, extensive planning.
- Read the EOB. If denied as included in the evaluation, the complexity narrative supports an appeal.
Example Case
An established patient presents with extensive wear, several failing restorations, and missing teeth, and is interested in a full-mouth rehabilitation. After the initial evaluation and records visit, the dentist schedules a separate appointment to develop and present a detailed, phased treatment plan — walking the patient through the sequencing, the disciplines involved, and the options. This dedicated case-presentation session is reported as D9450, documented with the plan and the complexity that justified it, and billed on a different day than the evaluation. The evaluations, imaging, and eventual treatment are each coded separately.

Frequently Asked Questions
How is D9450 different from the planning included in an evaluation?
Every evaluation includes some routine treatment-planning discussion, and that talk is already bundled into codes like D0150 and D0120. D9450 is different: it reports a detailed and extensive case-presentation session for a genuinely complex case — full-mouth rehab, multi-phase, or multi-discipline work. Using D9450 for the ordinary treatment discussion that accompanies a standard exam is a misuse and a common reason these claims are denied.
What's included in D9450, and what's billed separately?
D9450 reports only the detailed case-presentation and treatment-planning session. The evaluations, radiographs, diagnostic models, and the actual treatment that follows are not included and are each coded separately. Because the descriptor indicates the planning is generally performed on a different day than the evaluation, D9450 is meant to capture distinct, dedicated planning time rather than work bundled into other visits.
How often will insurance cover D9450?
Coverage is limited and inconsistent. Many plans consider treatment planning part of the evaluation and do not separately reimburse D9450, while others cover it only for documented complex cases. When it is covered, payers typically expect a narrative establishing the extensive planning involved. Always verify the specific plan's policy on case-presentation and planning charges before assuming D9450 will be reimbursed.
Can D9450 be billed on the same day as an evaluation?
Usually not. The descriptor indicates D9450 is generally not performed on the same date as an evaluation, since the evaluation already includes its own treatment-planning discussion. Billing both for the same day commonly leads to a denial of the planning charge as bundled into the exam. To support D9450, document it as a distinct case-presentation session, typically scheduled on a different day from the evaluation.
