The use of code Z79.4 to indicate long-term current use of insulin is only used for patient’s who are type II diabetic. Some type II diabetics require insulin use to control their blood sugars and others do not.
The following 72,752 ICD-10-CM codes are billable/specific and can be used to indicate a diagnosis for reimbursement purposes as there are no codes with a greater level of specificity under each code. Displaying codes 1-100 of 72,752: A00.0 Cholera due to Vibrio cholerae 01, biovar cholerae. A00.1 Cholera due to Vibrio cholerae 01, biovar eltor. A00.9 Cholera, unspecified.
The new codes are for describing the infusion of tixagevimab and cilgavimab monoclonal antibody (code XW023X7), and the infusion of other new technology monoclonal antibody (code XW023Y7).

Long term (current) drug use - V58. 6 codes are for use for when the patient has been on a medication for an extended time, or when the medication has been currently prescribed with the intent of long term use.
Therapeutic drug monitoring (TDM) is testing that measures the amount of certain medicines in your blood. It is done to make sure the amount of medicine you are taking is both safe and effective. Most medicines can be dosed correctly without special testing.
ICD-10-PCS GZ3ZZZZ is a specific/billable code that can be used to indicate a procedure.
If the type 2 diabetic patient uses insulin or oral hypoglycemic medication, the medications can be coded as Z79. 4 or Z79. 84, respectively. If the diabetic patient takes both oral medication and insulin, it is only necessary to code the insulin usage.
If the patient is treated with oral hypoglycemic medication and insulin, only assign the Z79. 4 for long-term use of insulin, which is not a change for 2021. If the patient is treated with both insulin and injectable non-insulin anti-diabetic drug, assign Z79.

Diabetes comes in several different forms (E08, E09, E10, E11, & E13 [I don't know what happened to E12, but it is not a code for anything]). E10 is Type I, which is by definition Insulin Dependent Diabetes in which Insulin is the basic/primary medication for Blood Sugar control/management.
Therefore, since the patients with this disorder are on Insulin primarily, the use of Z79.4 (long term/ current use of Insulin) would not be indicated. However, there are other types of Diabetes which are basically secondary to some other condition, or disease, or post-procedural in origin.
Cheezum51 said: Alan, from what I've been taught, you are correct. If you use an I10 code for Type I diabetes, it's assumed the patient is using insulin and you don't need to also code the Z79.4. If they have other forms of diabetes and insulin is used as part of their treatment, then you have to code the Z79.4.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an exact match to ICD-9 code 279.4:
Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.
If a type II diabetic is using insulin it is important to report that with a Z code because the use of this medication will affect the physician’s management of the patient. Type I diabetics require the use of insulin to live.
The use of insulin is implied in the diagnosis of Type I diabetes itself. Since this is the case, it is not necessary to report a Z code for long-term insulin use because it would be understood that this patient would be using insulin.
