Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.

Encounter

An outpatient clinician evaluates a generalized drug-induced rash after oral amoxicillin. The patient took the prescribed amount by the prescribed route.

Medication review

The provider confirms that the drug was correctly prescribed and properly administered. No overdose, wrong medication, interaction classified as poisoning, or reduced dose is documented.

Assessment

The signed assessment attributes the rash to an adverse effect of correctly used amoxicillin. No anaphylaxis or respiratory involvement is diagnosed.

Task boundary

This exercise asks for the event classification and sequence, not an unsupported exact drug code.

Your coding worksheet

Extract the facts about prescription and administration.
Choose the adverse-effect or poisoning pathway and explain why.
State which part of the coding sequence comes first.
Describe the table-to-Tabular verification needed for the actual drug.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Compare with the worked explanation

The medication was correctly prescribed and properly administered.
These facts support the adverse-effect pathway rather than poisoning or underdosing.
Code the nature of the reaction first, followed by the appropriate drug adverse-effect entry.
Amoxicillin is identified. Look it up in the drug table and verify the adverse-effect candidate and required encounter character in the Tabular List.
