Adverse effect of other general anesthetics, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to a general anesthetic other than an opioid or barbiturate. These sequelae are persistent health problems that manifest after the acute phase of the adverse effect has resolved.

Apply this code when documenting a patient presenting with a chronic or permanent complication directly attributable to a previous adverse event involving a general anesthetic (e.g., propofol, ketamine, sevoflurane). This is used for conditions that are no longer acute but represent a lasting consequence of the initial adverse effect.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past adverse effect of a general anesthetic.
• Do not use for acute adverse reactions; those require codes from the initial encounter or subsequent encounter categories.
