D9219Evaluation for Moderate Sedation, Deep Sedation, or General Anesthesia

What This Code Covers

D9219 covers the pre-anesthesia evaluation performed to assess a patient's medical status and suitability for moderate sedation, deep sedation, or general anesthesia. This includes reviewing medical history, current medications, airway assessment, and determining the appropriate anesthesia plan. This evaluation is separate from and prior to the actual administration of sedation or anesthesia.

Billing Guide

Bill this code when:

• A comprehensive pre-anesthesia evaluation is performed before sedation or general anesthesia
• The evaluation includes medical history review, airway assessment, and anesthesia risk classification (ASA status)
• The evaluation is performed on a date separate from the anesthesia administration
• The provider documents a formal anesthesia plan based on the evaluation

Do not bill this code when:

• The evaluation is performed on the same date as the sedation/anesthesia and is considered part of the anesthesia service
• A routine oral evaluation is performed. Use D0120 or D0150
• The patient is only receiving local anesthesia (D9210-D9212)
• The evaluation does not result in a formal anesthesia plan

Insurance and Denial Prevention

Key Payer Rules:

• D9219 is typically covered only when billed on a date prior to the anesthesia administration
• Some payers bundle the evaluation into the sedation/anesthesia codes if performed same-day
• Documentation of medical necessity for the separate evaluation visit is important
• Most commonly billed by oral surgeons and dental anesthesiologists

Common Denials and How to Respond:

• Bundled with anesthesia - If the evaluation was on a separate date, appeal with documentation showing the distinct service dates and medical necessity for a pre-operative evaluation.
• Not medically necessary - Submit documentation of the patient's complex medical history or ASA classification that required a dedicated evaluation visit.
• Should be D0140 - Clarify that this is a pre-anesthesia medical evaluation, not a dental evaluation. The focus is on anesthesia risk assessment.
