Every year, a new ICD-10 Clinical Modification (ICD-10-CM) code set is released which takes effect on October 1. There were 252 new codes added, 36 code deletions, and 13 code revisions effective October 1, 2024. Some of these changes involved ICD-10-CM coding for diabetes.
Until October 1, 2024, the diabetes code stems E08-, E09-, E11-, E13- all carried with them the instruction to “use additional code to identify control” using either:
Z79.4 – Long term (current) use of insulin
OR
Z79.84 – Long term (current) use of oral hypoglycemic drugs
These two options did not include the ability to indicate the use of injectable non-insulin antidiabetic drugs. Starting October 1, 2024, this will be addressed by adding the third option of:
Z79.85 – Long-term (current) use of injectable non-insulin antidiabetic drugs
Under the E10- type 1 diabetes codes, there is a new 4th character option of “A” in the new code set which represents pre-symptomatic type 1 diabetes. With this new 4th character option, the new E10- codes include:
- E10.A- Type 1 diabetes mellitus, presymptomatic (needs 5th character)
- E10.A0 Type 1 diabetes mellitus, presymptomatic, unspecified
- E10.A1 Type 1 diabetes mellitus, presymptomatic, Stage 1
- E10.A2 Type 1 diabetes mellitus, presymptomatic, Stage 2
