2025 ICD-10-CM code Z79.84

Long-term (current) use of oral hypoglycemic drugs.

A corresponding procedure code must accompany a Z code if a procedure is performed. Code also any follow-up examination (Z08-Z09) and any therapeutic drug level monitoring (Z51.81)

This code is used to document the ongoing management of type 2 diabetes with oral medication, which is medically necessary to control blood sugar levels and prevent complications.

IMPORTANT:If the patient is treated with both oral hypoglycemic drugs and injectable non-insulin anti-diabetic drugs, code Z79.84 and Z79.85. If the patient is treated with both insulin and injectable non-insulin anti-diabetic drugs, assign codes Z79.4 and Z79.85. If the patient is treated with both oral hypoglycemic drugs and insulin, code both Z79.84 and Z79.4.

In simple words: This code indicates that the patient is taking oral medication for their type 2 diabetes long-term.

Long-term (current) use of oral hypoglycemic drugs. This code is used for patients with type 2 diabetes who are currently taking oral medication to manage their condition. It excludes long-term use of injectable non-insulin antidiabetic drugs (Z79.85) and long-term use of insulin (Z79.4).

Example 1: A 60-year-old patient with type 2 diabetes is taking Metformin daily to control their blood sugar levels., A 45-year-old patient recently diagnosed with type 2 diabetes is prescribed Glipizide. This code is used to document the ongoing use of the medication., A patient with type 2 diabetes is taking both oral hypoglycemic medication and insulin. Both Z79.84 and Z79.4 would be coded.

Documentation should support the long-term use of oral hypoglycemic medications for the treatment of type 2 diabetes. The specific medication(s) being used should also be documented.
