Provider Actions & Billing Rules

Documentation Required

Support medical necessity with documentation

Medical conditions requiring general anesthesia or moderate sedation must be supported by documentation from the oral surgeon, dentist and/or physician; include radiographs, progress notes, operative report and complete anesthesia record for procedures >60 minutes.

Radiographs (all associated radiographic images)
Progress notes
Operative report
Complete anesthesia record indicating start and stop times of incremental drug administration
Anesthesia record including names of drugs, times and dosages (including local anesthetics or other agents)

Documentation Required

Record monitoring parameters

Continuously monitor and document oxygenation (including mucosal color), pulse oximetry, ventilation (chest movement, respirations), circulation (blood pressure, heart rate) pre/intra/post-operatively, and list all drugs with times and dosages.

Background and Definitions

The policy describes a continuum of sedation levels — anxiolysis, analgesia, intravenous moderate sedation, and deep sedation/general anesthesia — defined by the effect of agents on the central nervous system and aligned with ADA/AAP/AAPD/ASA guidance. Dental professionals administering anesthesia must be appropriately educated, trained, and licensed; for advanced anesthetics (IV or inhalation), additional individuals with Advanced or Basic Life Support credentials and, where required by state, current equipment inspection, sedation license and CPR certification must be present.

Monitoring and facility readiness requirements include continuous in‑operatory monitoring by the dentist or an appropriately trained individual until discharge criteria are met, observation of oxygenation (including mucosal color), use of pulse oximetry, continuous ventilation and circulation assessment (pre/intra/post‑op blood pressure and heart rate), and maintenance of a complete anesthesia record listing drugs, times, dosages and physiologic parameters. The dentist is responsible for emergency management, appropriate equipment, drugs, staff and office protocols.

Term	Definition
Deep sedation/general anesthesia	Drug-induced loss of consciousness where patients are unarousable, even by painful stimulation; cardiovascular function might be impaired.
Intravenous moderate sedation	Drug-induced depression of consciousness where the person remains awake, able to follow directions, with adequate spontaneous breathing and cardiovascular function.
Analgesia	Drug-induced depression of consciousness in which a person is not easily aroused but responds purposefully after repeated or painful stimulation; airway assistance may be required.
Anxiolysis	Drug-induced state allowing a person to respond normally to verbal commands with preserved airway reflexes and breathing.
Medically/Dentally Necessary	Services consistent with the member's diagnosis or condition, rendered for life‑threatening condition or pain, to treat dentition-related injury/illness/infection, or to achieve functional dentition consistent with community standards.

On This Page

The member is a child, up to the age defined by contract, with a dental condition requiring repairs of significant complexity (examples: multiple restorations, pulpal therapy, extractions or combinations of such procedures).
The member has physical, intellectual, or medically compromising conditions for which dental treatment under local anesthesia cannot be expected to provide a successful result (examples include intellectual disabilities, cerebral palsy, epilepsy, severe cardiac problems, hyperactivity). Requires appropriate medical documentation.
The member is extremely uncooperative, fearful, unmanageable, anxious, or uncommunicative with complex dental needs that should not be postponed and for whom lack of treatment may result in oral pain, infection, loss of teeth, or increased oral morbidity.
Local anesthesia is ineffective for the member (reasons such as acute infection, anatomic variations or allergy). Failed attempts of local anesthesia administration must be documented and submitted for review.
The member has sustained extensive oral-facial and/or dental trauma for which treatment under local anesthesia would be ineffective or compromised.

Medical conditions requiring general anesthesia or moderate sedation must be supported by documentation submitted by the oral surgeon, dentist and/or physician administering the anesthesia.

The level of anesthesia is determined by the documented effect on the patient's central nervous system, not solely by the route of administration.

Time of general anesthesia begins when the dentist starts administering the sedative agent and non-invasive monitoring protocol; the dentist must remain in constant attendance until completion.

Services are complete when the patient can be safely left under observation of trained personnel and the dentist may leave the operatory.

Office anesthesia in excess of 60 minutes for any dental or surgical procedure requires a written rationale/documentation explaining the necessity, including all associated radiographic images, progress notes, operative report and a complete anesthesia record indicating start and stop times of incremental drug administration.

Inhalation of Nitrous Oxide/Analgesia

Nitrous oxide may be benefitted when appropriate in conjunction with covered dental services and is indicated/contraindicated as follows:

ALL of the following

Nitrous oxide may be indicated for
- Ineffective local anesthesia administration
- Treatment of dental anxiety
- Special needs patients
- Individuals who are uncooperative or behaviorally challenged
Nitrous oxide is contraindicated for, but not limited to
- Patients with severe respiratory compromise
- First trimester pregnancy because of its potential teratogenic effects
- Patients with a history of stroke
- Hypotension and known cardiac conditions

Monitoring and Documentation Requirements

Required monitoring and documentation during anesthesia:

A dentist or appropriately trained individual must remain in the operatory during active dental treatment to continuously monitor the patient's vital signs until discharge criteria to recovery area are met.

Monitoring must include observation of proper oxygenation (including mucosal color) and continuous evaluation of skin or blood; oxygen saturation by pulse oximetry is appropriate and necessary.

Ventilation: chest movement must be continually observed; respirations must be verified and documented by appropriately trained personnel.

Circulation: blood pressure and heart rate must be evaluated pre-operatively, intra-operatively and postoperatively and properly documented.

Documentation: maintain a complete anesthesia record including names of drugs administered, time and dosages, and all physiological parameters.

Emergency management: dentist responsible for drug management, adequacy of facility and staff, and provision of appropriate equipment, drugs and protocol for emergency management.

Oxygenation: observation of mucosal color and continual evaluation; pulse oximetry
Ventilation: continuous observation of chest movement; document respirations
Circulation: blood pressure and heart rate pre-, intra- and post-operatively
Drug administration: names of drugs, times of administration and dosages

Prior Authorization

Benefit determination tied to contract/age limits

Coverage for pediatric patients up to contract-defined ages follows contract terms and state mandated ages for IV and inhalation anesthesia; verify the member's contract and obtain any required reviews prior to scheduling.

Verify member contract for age limits and state-mandated ages for IV/inhalation anesthesia
Obtain any prior authorization or required review specified by the member's plan before scheduling

Billing Rule

Local anesthesia not separately payable

The administration of local anesthetic (traditional, electronic, buffered, etc.) is considered inclusive of all dental procedures and is generally not eligible for a separate benefit unless the member's specific plan allows separate coverage.

Affected codes: D9210, D9215
Rule: Local anesthesia is considered inclusive and generally not separately billable unless the plan explicitly allows separate coverage

Denial Risk

Regional/trigeminal block may be non-covered

Regional and trigeminal division block anesthesia may not be a covered service; claims for these services (when billed separately) may be denied if not allowed under the member's plan.

Affected codes: D9211, D9212
Denial risk guidance: May be non-covered — verify member contract benefits prior to performing or billing

Documentation Required

Failed local anesthesia attempts

If local anesthesia is ineffective, failed attempts of local anesthesia administration must be documented and submitted for review to qualify for an advanced anesthesia benefit.

Document failed local anesthesia attempts (reason such as acute infection, anatomic variation, allergy)
Submit documentation for review to support eligibility for advanced anesthesia (moderate or general anesthesia)

Documentation Required

Anesthesia time accounting

Record anesthesia time beginning when the dentist starts administering the sedative agent and monitoring protocol; document start and stop times and bill using appropriate 15-minute increment codes.

Affected time codes: D9222, D9223, D9224, D9225, D9239, D9243, D9246, D9247
Document anesthesia start and stop times on the anesthesia record
Use 15-minute increment codes (first and subsequent increments) for billing
