READER QUESTIONS:

Check ICD-9 Table of Drugs for Insulin OD Diagnosis

Published on Tue Sep 11, 2007

Question: Our patient injected too much insulin and experienced dizziness and blurred vision. Which ICD-9 code(s) should we report for this?


Tennessee Subscriber
Answer: Because the patient took the wrong dosage, your primary ICD-9 code will be the poisoning code for the drug taken, followed by symptom codes. Because the diabetic patient injected the wrong insulin dose, you should refer to ICD-9's -Table of Drugs and Chemicals,- find insulin and report the code that appears in the -poisoning- column--962.3 (Poisoning by insulins and antidiabetic agents).

You should then report the patient's symptoms. For example, if the patient presented with light-headedness and blurred vision after taking the insulin, you should report 780.4 (Dizziness and giddiness) and 368.8 (Other specified visual disturbances, blurred vision NOS). --Answers to You Be the Coder and Reader Questions reviewed by Kent J.
