Underdosing of other general anesthetics, initial encounter

This code signifies that a patient received an insufficient dose of a general anesthetic other than an inhaled or intravenous agent, leading to an adverse effect or inadequate anesthesia. This underdosing resulted in a negative clinical outcome or failure to achieve the desired anesthetic depth during the initial encounter with the healthcare system for this specific event.

Apply this code when documentation clearly indicates that a patient experienced complications or an unsatisfactory anesthetic effect due to being given too little of a general anesthetic (excluding inhaled or IV types). This would include situations where the patient woke up prematurely during surgery or experienced pain due to insufficient anesthetic, and it's the first time this particular underdosing event is being treated.

• Ensure the documentation specifies "underdosing" and not an adverse effect from a correctly administered dose.
• Verify that the anesthetic agent involved is a "general anesthetic" but not an inhaled or intravenous type, as those have separate codes.
• Confirm this is the "initial encounter" for the treatment of the underdosing event; subsequent encounters would use a different seventh character.
