Answer:
Code 42820-42826 refers to tonsillectomy, so the medical record should have information on how this procedure was performed.
Step-by-step explanation:
The medical record is the set of standardized and ordered documents, where all professional care provided to patients must be recorded and attest to the medical care given to a person in a healthcare institution or doctor's office. A chart coded 42820-42826 indicates that the patient underwent a tonsillectomy, so the medical record should contain all information about the procedure, such as start and end time, patient age, if there were any complications, and other information.
