Managing patient anxiety during dental procedures directly impacts treatment outcomes and patient retention. For patients who cannot tolerate treatment with local anesthesia alone, non-intravenous conscious sedation offers a safe alternative that maintains patient responsiveness while reducing fear. Billing this service accurately requires understanding which routes of administration qualify and what documentation supports medical necessity. This guide clarifies when D9248 applies, how it differs from other sedation codes, and what records practices need to maintain for successful reimbursement.

What Is Dental Code D9248?
D9248 refers to non-intravenous conscious sedation, covering sedation delivered through routes other than direct venous access. This includes oral medications, intramuscular injections, intranasal administration, submucosal injections, transmucosal delivery, and transdermal application. The patient remains conscious throughout treatment, able to respond purposefully to verbal commands while maintaining protective reflexes and adequate spontaneous ventilation.
The code applies to both minimal and moderate levels of conscious sedation when delivered through non-IV routes. The level of sedation achieved depends on the medications used and patient response, not the route of administration.
Common Terminology
Several clinical terms appear frequently when documenting D9248 services.
Conscious sedation: A drug-induced depression of consciousness where the patient retains the ability to respond purposefully to verbal commands, either alone or with light tactile stimulation, while maintaining protective reflexes and adequate spontaneous ventilation
Enteral route: Medication delivery through the gastrointestinal tract or oral mucosa, including oral, rectal, and sublingual administration
Parenteral route: Medication delivery that bypasses the gastrointestinal tract, including intramuscular, intranasal, submucosal, subcutaneous, and intraosseous administration (but excludes intravenous delivery for purposes of D9248)
Transmucosal administration: Drug delivery across mucous membranes such as intranasal, sublingual, or rectal tissues
Monitoring parameters: Vital signs tracked throughout sedation including oxygen saturation via pulse oximetry, heart rate, blood pressure, and respiratory rate
When Is D9248 Used?
D9248 applies when practices administer conscious sedation through non-intravenous routes to manage anxiety, facilitate behavior, or enable completion of dental treatment. The patient must remain responsive to verbal commands throughout the procedure. This code supports care for patients who would otherwise avoid treatment or cannot tolerate procedures with local anesthesia alone.
Medical necessity and appropriate route of administration determine when this code applies.
Common Clinical Scenarios
Certain patient presentations and clinical situations create clear indications for non-IV conscious sedation.
Pediatric patients requiring behavior management support during restorative or surgical procedures who cannot cooperate with local anesthesia alone
Adult patients with moderate to severe dental anxiety that prevents treatment completion
Patients with special needs or developmental disabilities affecting cooperation and communication
Individuals with strong gag reflexes or heightened oral sensitivity interfering with treatment delivery
Complex procedures requiring extended appointment times where patient comfort becomes challenging to maintain
Patients with medical conditions contraindicated for IV access but requiring sedation for successful treatment
Situations where IV sedation training or equipment is unavailable but patient needs exceed what local anesthesia provides
When D9248 Is NOT Appropriate
Understanding when to avoid this code prevents billing errors and potential compliance issues.
When intravenous sedation is administered, which requires coding with D9239 (first 15 minutes) and D9243 (each subsequent 15 minutes)
For deep sedation or general anesthesia where patients lose consciousness and cannot respond purposefully, covered by D9222 (first 15 minutes) and D9223 (each subsequent 15 minutes)
When nitrous oxide serves as the sole sedative agent without additional sedation medications, billed separately as D9230
In situations where patients receive only local anesthesia without any sedation protocol
For minimal anxiolysis where no formal sedation monitoring protocol is implemented
When an outside anesthesia provider administers sedation rather than the treating dental practice
Billing and Insurance Considerations
Proper billing for D9248 demands meticulous documentation and understanding of payer policies. Insurance companies scrutinize sedation claims carefully, often requiring evidence that the sedation was medically necessary rather than for convenience. Many plans impose restrictions based on patient age, diagnosis, or procedure type. Prior authorization requirements vary significantly across carriers, making verification before treatment critical to reimbursement.
Medical necessity justification and comprehensive clinical records determine whether claims process successfully.
Documentation Requirements
Strong documentation establishes medical necessity and supports appropriate payment for non-IV conscious sedation services.
Pre-sedation evaluation including comprehensive medical history review, current medications, allergies, and American Society of Anesthesiologists (ASA) physical status classification
Clinical justification explaining why sedation was necessary for this specific patient and procedure, documenting anxiety level, behavior challenges, or medical conditions affecting cooperation
Informed consent signed by patient or legal guardian, outlining risks, benefits, and alternatives to non-IV conscious sedation
Specific medications administered including generic and brand names, exact dosages, routes of administration (oral, intramuscular, intranasal, submucosal, etc.), and precise times given
Continuous monitoring records documenting oxygen saturation, heart rate, blood pressure, and respiratory rate at regular intervals throughout sedation and procedure
Clinical notes describing patient's level of consciousness and responsiveness during treatment, confirming conscious sedation level was maintained
Post-sedation recovery documentation showing vital signs, level of consciousness, and specific discharge criteria met before patient departure
Names, roles, and credentials of all personnel involved in sedation administration, monitoring, and recovery supervision
Any adverse events, complications, or interventions required during sedation or recovery periods
Insurance Coverage
Coverage for D9248 varies dramatically across dental benefit plans and depends heavily on patient-specific factors.
Pediatric cases typically receive more favorable coverage than adult procedures, particularly for patients under age six or with documented behavioral management needs
Many plans require documented anxiety disorders, developmental disabilities, or special needs as justification for coverage
Some carriers mandate proof of failed treatment attempts using local anesthesia alone or behavioral techniques before approving sedation
Medical insurance may provide coverage when dental procedures relate directly to medical conditions, trauma, or preparation for medical procedures, requiring coordination of benefits between medical and dental plans
Age restrictions commonly apply, with some plans limiting coverage to children or excluding routine adult procedures
Prior authorization requirements differ widely, with some carriers requiring advance approval while others conduct retrospective reviews
Out-of-network billing rates typically result in higher patient financial responsibility through balance billing
Common Billing Mistakes
Several errors appear repeatedly in D9248 claims, creating denials and revenue loss.
Failing to document specific medical necessity, particularly why non-IV sedation was clinically required rather than using only local anesthesia, nitrous oxide, or behavioral techniques
Confusing D9248 with IV sedation codes (D9239/D9243) when the medication was actually delivered intravenously
Missing continuous monitoring parameter documentation at appropriate intervals throughout the sedation period
Omitting the exact route of administration, medication names, and dosages used during sedation
Not recording pre-sedation evaluation findings including ASA classification and medical history review
Inadequate recovery documentation failing to show patient met specific discharge criteria before leaving the facility
Billing D9248 when nitrous oxide was used as the sole agent, which requires separate coding under D9230
Not obtaining required prior authorization from carriers mandating advance approval for sedation services
Submitting claims without provider sedation credentials or permit numbers when payers require this information
Common Questions
How often can D9248 be billed?
Each date of service where non-IV conscious sedation is administered constitutes a separate billable event. No arbitrary frequency limitations exist from most insurance carriers, but clinical necessity must justify each sedation episode. Practices should demonstrate that each use of D9248 corresponds to substantial dental treatment requiring anxiety management or behavior support. Excessive frequency relative to procedures performed may trigger payer review questioning medical necessity.
What medications are typically used for D9248?
Common medications for non-IV conscious sedation include oral benzodiazepines such as midazolam, diazepam, or triazolam, antihistamines like hydroxyzine, and combinations designed to achieve anxiolysis without deep sedation. Pediatric dentistry may use chloral hydrate or meperidine combinations administered orally or intramuscularly. The specific agent selection depends on patient age, weight, medical history, anxiety level, and procedure requirements. Documentation must specify which medications were administered, their dosages, and the exact route used to support the D9248 code.
Does D9248 cover the full appointment time?
D9248 covers sedation administration, continuous monitoring during treatment, and recovery supervision until discharge criteria are met. The code does not include the actual dental procedures performed, which must be billed separately using their respective CDT codes. Unlike IV sedation codes that bill in 15-minute increments, D9248 is billed once per appointment regardless of duration. Total sedation time varies based on medication onset, procedure length, and individual patient recovery time.
What's the difference between D9248 and D9239?
D9248 covers non-intravenous conscious sedation using routes such as oral, intramuscular, intranasal, submucosal, or transmucosal administration. D9239 specifically covers intravenous conscious sedation for the first 15 minutes, with D9243 covering each subsequent 15-minute increment. The critical distinction is the route of medication delivery, not the level of sedation achieved. Practices must select codes that accurately reflect how sedation was actually administered to avoid billing errors and potential compliance issues.
Can D9248 be billed with nitrous oxide on the same day?
Yes, when both are clinically indicated and properly documented. Some patients receive nitrous oxide inhalation (D9230) as an adjunct to non-IV sedation medications, particularly during longer procedures or when anxiety levels require additional support. Bill D9230 for nitrous oxide separately from D9248, ensuring documentation clearly explains why both modalities were necessary for this specific patient and procedure. Insurance may question combined billing, so clinical justification strengthens claims and reduces denial risk.
What training or certification is required to bill D9248?
State dental boards mandate specific education, training, and facility requirements for practitioners administering conscious sedation. Requirements vary by jurisdiction but typically include completion of an accredited sedation training program, current Basic Life Support (BLS) certification, possession of emergency medications and equipment, and maintenance of a valid sedation permit. Some states differentiate between pediatric and adult sedation credentials. Practices must maintain documentation of provider qualifications, continuing education, facility inspections, and regulatory compliance to support billing and defend against potential audits.
How do monitoring requirements differ from IV sedation?
While the sedation route differs, monitoring standards for D9248 remain rigorous and similar to IV sedation requirements. Practices must continuously track vital signs including oxygen saturation via pulse oximetry, heart rate, blood pressure, and respiratory rate throughout the procedure. A trained team member dedicated to monitoring remains essential even though IV access is not established. Documentation standards closely mirror those for IV sedation to ensure patient safety, regulatory compliance, and billing support. State regulations specify minimum monitoring requirements that practices must follow.
Do all routes of administration have the same onset time?
No, onset times vary significantly based on the route used. Oral medications typically require 30 to 60 minutes for full effect due to gastric absorption and hepatic first-pass metabolism. Intramuscular injections usually take effect within 15 to 30 minutes. Intranasal and submucosal routes often produce faster onset than oral administration due to more rapid absorption into the bloodstream. These timing differences affect appointment scheduling, patient instructions, and when procedures can safely begin. Documentation should reflect medication timing and patient response to support proper sedation management.
