CDT Code D9987: Cancelled Appointment Billing

What Is D9987? (CDT Code Overview)

CDT code D9987 — Cancelled Appointment Billing — falls under the Adjunctive General Services category of CDT codes, specifically within the Other Adjunctive Services subcategory. Understanding when and how to use this code is essential for accurate billing, clean claim submission, and optimal reimbursement at your dental practice.

When Should You Use D9987?

D9987 is specifically for cancelled appointments. Based on current CDT standards, this code applies when patients cancel without adequate notice, usually under 24 hours prior to their appointment, and the office policy permits cancellation charges. This code doesn't apply to patient no-shows (which use D9986), or practice-initiated cancellations. Make sure your cancellation policy is clearly explained to patients and properly documented.

Quick reference: Use D9987 when the clinical scenario specifically matches cancelled appointment billing. Do not use this code as a substitute for related procedures in the same category. Consider whether D9910 (Desensitizing Medicament Application) or D9911 (Desensitizing Resin Application) might be more appropriate instead.

D9987 vs. Similar CDT Codes: Key Differences

Dental teams frequently confuse D9987 with other codes in the other adjunctive services range. Here is how D9987 differs from the most commonly mixed-up codes:

• D9910: Desensitizing Medicament Application — While D9910 covers desensitizing medicament application, D9987 is specifically designated for cancelled appointment billing. Selecting the wrong code can trigger claim denials or audits, so always verify the clinical scenario matches the code definition before submitting.

• D9911: Desensitizing Resin Application — While D9911 covers desensitizing resin application, D9987 is specifically designated for cancelled appointment billing. Selecting the wrong code can trigger claim denials or audits, so always verify the clinical scenario matches the code definition before submitting.

• D9920: Behavior Management by Report — While D9920 covers behavior management by report, D9987 is specifically designated for cancelled appointment billing. Selecting the wrong code can trigger claim denials or audits, so always verify the clinical scenario matches the code definition before submitting.

Documentation Requirements for D9987

Proper documentation is essential for D9987 usage. Recommended practices include:

• Recording cancellation date and time details.

• Documenting patient's cancellation reason when available.

• Including reference to your written cancellation policy in patient records.

• Recording all communication efforts (phone calls, messages, emails) about the appointment and its cancellation.

Typical clinical situations include:

• Patient calling on appointment day to cancel due to sickness.

• Patient cancelling hygiene appointment with less than 24-hour notice.

• Patient cancelling treatment procedure on short notice when office policy includes cancellation fees.

Documentation checklist for D9987:

• Patient chief complaint and relevant medical/dental history clearly recorded.

• Clinical findings that support the use of D9987 specifically (not a more general or more specific code).

• Any diagnostic tests, imaging, or supplementary data that justify the procedure.

• Treatment plan with rationale connecting the diagnosis to the procedure coded as D9987.

• Post-procedure notes, including outcomes and follow-up recommendations.

Insurance and Billing Guide for D9987

Most dental insurance providers do not cover cancellation charges, including D9987 fees. Nevertheless, entering this code in your practice software remains important for internal monitoring and maintaining proper accounts receivable (AR) tracking. Recommended approaches for D9987 management include:

• Confirming patient responsibility for cancellation charges during benefit verification.

• Explaining your cancellation policy and related fees to patients when scheduling and in appointment reminders.

• Adding D9987 as a charge to patient accounts, and billing if payment isn't received when cancelled.

• When patients question the charge, refer to your documented cancellation policy and records in any discussions or appeals.

Common denial reasons for D9987: Lack of clinical documentation, frequency limitations exceeded, code mismatch with diagnosis, or missing prior authorization. When appealing a denied D9987 claim, include a detailed narrative explaining why the procedure was necessary, supporting clinical evidence, and relevant imaging or test results. Many practices find that well-documented first submissions dramatically reduce the need for appeals.

Real-World Case Example: Billing D9987

A patient presents requiring a procedure consistent with D9987 (cancelled appointment billing).

Frequently Asked Questions About D9987

Can D9987 be applied to same-day rescheduling or only to completely missed appointments?

The D9987 code is primarily designed for missed appointments or cancellations that don't provide adequate notice based on your practice's established policy. When a patient reschedules on the same day and your office policy considers this equivalent to a missed appointment, D9987 may be appropriately used. Conversely, if your practice policy permits same-day rescheduling without penalties, then D9987 should not be applied. It's crucial to consistently follow your documented office policies and ensure all patients understand your rescheduling guidelines.

What's the best approach for managing patients who chronically miss appointments?

When dealing with patients who have a pattern of missing appointments, practices can utilize D9987 to maintain detailed records of no-show incidents over time. This comprehensive documentation supports informed decisions regarding requiring advance deposits, restricting future appointment availability, or potentially removing the patient from your practice. Maintaining consistent enforcement of your cancellation policies and maintaining clear patient communication is vital. Consider having a direct conversation with the patient about their attendance pattern and ensure all interactions are thoroughly documented in their patient file.

Should patients sign an acknowledgment of the cancellation policy before D9987 can be used?

Obtaining a patient's written acknowledgment of your cancellation and missed appointment policy is strongly recommended as a best practice. This signed documentation serves as important legal and ethical protection should a patient challenge a missed appointment charge. Store the signed policy acknowledgment in the patient's permanent record and reference this documentation when implementing D9987 or resolving any related disputes that may arise.

What is the typical reimbursement range for D9987?

Reimbursement for D9987 (cancelled appointment billing) varies based on geographic location, payer contract terms, and whether the patient has in-network or out-of-network coverage. Fee schedules are typically set by individual insurance carriers, so practices should verify expected reimbursement during benefits verification. If your practice consistently receives lower-than-expected payments for D9987, consider renegotiating your fee schedule with major payers or reviewing your UCR (Usual, Customary, and Reasonable) data for your region.

Does D9987 require prior authorization?

Prior authorization requirements for D9987 depend on the patient's specific insurance plan. Some carriers require advance approval for procedures coded under D9987, while others process claims without it. Best practice is to verify authorization requirements during insurance eligibility checks before the appointment. If prior authorization is required, submit the request with detailed clinical notes and supporting documentation to avoid delays in patient care and claim processing.
