No material clinical or coverage changes in this revision.
Coverage Criteria for IV Moderate Sedation and General Anesthesia
Medical necessity criteria for IV moderate sedation/general anesthesia
Requests are considered medically necessary when ALL of the following are met (or when any one listed indication is documented):
Document attempts or reasons not feasible.
Either both items 1 and 2, or any single indication from the alternative list is acceptable.
Alternative single-indication pathway
- Inability to immobilize/unsafe: Use of effective communicative techniques and inability for immobilization (member may be dangerous to self or staff) failed or was not feasible based on the member's medical needs.
- Extensive treatment needs: Member requires extensive dental restorative or surgical treatment that cannot be rendered under local anesthesia or minimal sedation.
- Acute situational anxiety/immature cognition: Member has acute situational anxiety due to immature cognitive functioning.
- Uncooperative due to conditions: Member is uncooperative due to certain physical or mental compromising conditions.
High-acuity setting requirement
Members with certain medical comorbidities should be treated in hospital/licensed facility settings:
Facility and provider qualifications
Facility and provider requirements:
Applies to inpatient facilities, ambulatory surgery centers, and other licensed locations administering general anesthesia.
Inclusion or exclusion of any procedure or billing codes in this policy text does not, by itself, guarantee coverage. The codes listed are provided for informational purposes only and are not all‑inclusive. Providers must reference the most current professional coding guidance and the member's coverage documents when preparing claims and verifying benefits prior to submission.
This policy is intended to guide medical necessity determinations and does not enumerate specific scenarios that would be automatically considered not medically necessary. Coverage decisions remain subject to the member's benefit documents, exclusions, limitations, and applicable state or federal requirements. Providers should use this policy as clinical guidance and follow plan-level administrative policies when seeking coverage determinations.
Relevant Procedure and Dental Codes
| D9222 | Deep sedation/general anesthesia, first 15 minutes |
| D9223 | |
| D9239 | Intravenous moderate (conscious sedation/analgesia), first 15 minutes |
| D9243 | Intravenous moderate (conscious) sedation/analgesia, each subsequent 15 minutes |
Provider Requirements and Authorization
Prior Authorization Required
Prior authorization is required for requests for IV moderate sedation or general anesthesia in the listed settings per plan criteria. Submit prior authorization with complete clinical documentation to support medical necessity.
- Applicable settings: inpatient, ambulatory surgery center, community clinical or dental office (when indicated)
Stepwise Escalation Before IV/General Anesthesia
Behavior modification and local anesthesia should generally be attempted first. Minimal (inhalation or oral) sedation should be considered and documented as attempted or determined not feasible based on the member’s medical needs before escalating to IV moderate sedation or general anesthesia.
- Document attempts at behavior management and local anesthesia
- Document rationale if minimal sedation was not feasible or failed
Required Clinical Documentation
Clear medical record documentation must include: 1) use of local anesthesia or documentation why it was not feasible; 2) attempt or infeasibility of minimal sedation (inhalation or oral); and 3) any additional indications (e.g., inability to immobilize, extensive treatment needs, acute situational anxiety, uncooperative due to physical/mental conditions, or relevant medical comorbidities). Documentation should show clinical justification for IV moderate sedation or general anesthesia.
- Document specific attempts and outcomes for local anesthesia and minimal sedation
- Document behavioral/medical reasons (e.g., safety risk, extent of treatment, cognitive/behavioral limitations)
Coding and Billing Documentation
Providers should include relevant procedure and anesthesia coding on authorization requests and claims. Reference current CPT and HCPCS/Dental codes and ensure code descriptions match the services rendered. Providers are responsible for using up-to-date coding guidance prior to claim submission.
Documentation-based Denial Risk
Requests that do not meet the policy indications or that lack the required supporting documentation (attempts at local anesthesia/minimal sedation, clinical rationale for escalation, or appropriate coding) may be denied. Ensure all required clinical notes, procedure details, and code references are included with the prior authorization request to avoid documentation-based denials.
- Missing or incomplete documentation of attempted local or minimal sedation is a common reason for denial
- Include operative notes, anesthesia records, and explicit clinical rationale when applicable
Background and Clinical Context
Selection of IV moderate sedation or general anesthesia should be based on the patient's medical history, physical status, and the clinical indications for anesthetic management. Decisions should be made collaboratively by dental and anesthesia providers, taking into account behavior, procedural complexity, and any comorbid conditions that increase risk. Facilities and staff must be prepared and equipped to monitor and respond to anesthetic emergencies, and higher‑acuity settings should be used for members with significant medical comorbidities.
