These codes were collected in November, 2023; they may change.

This information is not a promise of coverage or payment, nor is it intended to give reimbursement advice or increase reimbursement by any payer. Legal requirements and plan information can be updated frequently. Contact the plan for more information about current coverage, reimbursement policies, restrictions, or requirements that may apply.

Sometimes the patient’s health plan may require a prior authorization (PA) before covering a treatment for diabetes. It is important to provide the correct information to ensure there are no delays in treatment. While payer and health plan requirements can vary, these PA submission forms often include ICD-10-CM diagnosis codes and requests for information regarding the patient’s treatment and medical history.

For more information about ICD-10, please visit the CMS website.
