When a patient experiences an underdose of insulin due to an insulin pump malfunction, the primary reason for the encounter would be the malfunction itself, which is coded first. The resulting hyperglycemia or hypoglycemia due to the pump failure is a secondary condition. According to ICD-10-CM guidelines, the code for the mechanical complication of the pump (T85.633-) is sequenced first, followed by a code for the diabetes with complication (E11.65 for type 2 diabetes with hyperglycemia).References: ICD-10-CM (current year), Chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes (S00-T88), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.4.

For a follow-up examination after the removal of polyps with no new polyps found, the appropriate diagnosis codes are:

Z09: Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm.

Z86.010: Personal history of colonic polyps.

Using Z09 indicates that the follow-up exam is to check the patient after treatment, and Z86.010 indicates a history of colonic polyps, which is relevant to the patient's medical history.
