Failed moderate sedation during procedure, sequela

This code signifies a patient experienced an unsuccessful attempt at achieving moderate sedation during a medical procedure, leading to a lasting or residual effect. This means the intended level of sedation was not reached or maintained, and the patient is now presenting with a consequence directly attributable to that failure.

Apply this code when a patient presents with a current condition or complication that is a direct result of moderate sedation failing to achieve its desired effect during a past procedure. This includes scenarios where a procedure had to be aborted, was completed with inadequate patient comfort/cooperation, or resulted in psychological trauma due to insufficient sedation, and the patient is now being treated for the sequela.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the prior failed moderate sedation.
• Do not use for acute, immediate complications of failed sedation; this code is for residual effects.
