Underdosing of local anesthetics, sequela

This code signifies a long-term consequence or complication arising from the insufficient administration of a local anesthetic. It indicates that the patient experienced an adverse outcome directly attributable to receiving less than the intended or therapeutic dose of a local anesthetic, and this outcome is now a persistent issue.

Apply this code when documenting a patient presenting with a chronic problem or permanent damage that is a direct result of an underdosed local anesthetic in the past. Examples include persistent nerve damage or chronic pain from an inadequately anesthetized procedure. This code is used for the sequela itself, not the acute underdosing event.

• Always assign a code for the specific sequela (e.g., chronic pain, nerve damage) in addition to this code.
• Ensure documentation clearly links the current sequela to a past underdosing event of a local anesthetic.
• This code is for the "S" (sequela) encounter, indicating the long-term effects are being treated.
