Loc skin eruption due to drugs and meds taken internally

This code signifies a localized skin reaction, such as a rash, urticaria, or fixed drug eruption, that is directly caused by a medication ingested or administered systemically. The eruption is confined to a specific area of the body rather than being generalized.

Use this code when documentation clearly links a localized dermatological manifestation to an internally administered drug. This applies to adverse reactions where the drug is the causative agent and the skin involvement is not widespread. Documentation should specify the drug and the localized nature of the eruption.

• Ensure the documentation explicitly states the skin eruption is localized and drug-induced.
• Always code the adverse effect of the drug first (T36-T50 with 5th or 6th character 5), followed by this code.
• Distinguish from generalized drug eruptions (L27.0) or contact dermatitis (L23-L25).
