HCPCS Code J1815: Injection, Insulin, Per 5 Units

It can be performed in a hospital, an outpatient clinic, or at home.

As with any injection, there will be pain and discomfort in the injection site. Adverse reactions include bruising, injection site infection (please use antiseptics before injecting the insulin to prevent this), allergic reactions, and hypoglycemia.

FDA-approved Oral anti-diabetic medication is a good alternative, but this will vary from patient to patient. It should only be an alternative if you can confirm that it suits the patient you're handling. It's also good to pair insulin shots or oral anti-diabetic medication with proposed lifestyle changes to maximize the benefits.
