Poisoning by other and unspecified local anesthetics

This code signifies an adverse reaction or toxicity resulting from the administration or exposure to a local anesthetic agent not specifically classified elsewhere. It encompasses systemic effects or localized complications arising from an overdose, hypersensitivity, or idiosyncratic response to these medications.

Assign this code when documentation clearly indicates poisoning by a local anesthetic, such as lidocaine, bupivacaine, or procaine, where the specific agent is not detailed or falls outside more specific categories. This applies to scenarios like accidental overdose during a procedure, intentional ingestion, or adverse systemic effects from therapeutic use.

• Always seek to identify the specific local anesthetic involved for more precise coding if available.
• Distinguish between poisoning (adverse effect due to incorrect dose/substance) and adverse effect in therapeutic use (correct dose/substance, but unexpected reaction), which would typically use E-codes.
• Sequencing will depend on whether the poisoning is the primary reason for the encounter or a complication of another condition.
