2025 ICD-10-CM code O29.3

Toxic reaction to local anesthesia during pregnancy.

Use additional codes to specify the trimester of pregnancy (Z3A.-) and any other complications arising from the toxic reaction. For example, if the patient experiences seizures as a result of the toxic reaction, an additional code for the seizures should be used.

Medical necessity for the use of local anesthesia should be documented, along with the rationale for the specific anesthetic chosen. This includes the procedure performed and its necessity during pregnancy. If a toxic reaction occurs, the medical necessity for the treatment provided should also be documented.

The clinician's responsibility includes careful selection of the local anesthetic, administration of the appropriate dose, monitoring the patient for adverse reactions, and providing prompt treatment if a toxic reaction occurs. Thorough documentation of the anesthetic used, dosage, patient response, and any treatment provided is essential.

In simple words: A bad reaction to a local anesthetic given during pregnancy.

Toxic reaction to local anesthesia administered during pregnancy. This code encompasses adverse reactions specifically to local anesthetics used during any trimester of pregnancy.

Example 1: A pregnant woman in her second trimester receives a local anesthetic during a dental procedure. She develops tremors and palpitations, indicating a toxic reaction to the anesthetic., A pregnant woman in her first trimester undergoes a biopsy requiring local anesthesia. She experiences seizures shortly after administration of the anesthetic, suggesting a toxic reaction., A pregnant woman in her third trimester receives a local anesthetic during a minor surgical procedure. She experiences localized swelling, redness, and pain at the injection site, indicating an allergic reaction, which should be distinguished from a systemic toxic reaction.

Documentation should include the type and dose of the local anesthetic administered, the onset and nature of the toxic reaction, any treatment provided, and the patient's response to treatment. If an allergy is suspected, this should be documented as well, along with any confirmatory testing performed.

** Distinguish between a toxic reaction to local anesthesia and other complications of pregnancy or other adverse reactions such as allergic reactions. This code applies to maternal records only, not newborn records.
