Several ICD-10-CM code changes took effect on October 1, 2025 [1], that will affect providers.
Type 2 Diabetes - E11.A Type 2 diabetes mellitus without complications in remission
The 2021 International Consensus Report defining type 2 diabetes in remission, coauthored by the ADA, EASD, Diabetes UK, the Endocrine Society, and others, defines type 2 diabetes in remission as “a return of HbA₁c to < 6.5% (48 mmol/mol) that persists for at least 3 months after stopping glucose—lowering pharmacotherapy.” [2]
When caring for a patient with type 2 diabetes in remission, that diagnosis should be reflected in the ICD-10-CM coding that accompanies the encounter if the type 2 diabetes in remission diagnosis played a role in the management provided during that encounter.
Effective October 1, 2025, a new, complete ICD-10-CM code will be:
- E11.A Type 2 diabetes mellitus without complications in remission
Shin Ulcers L97.2
Non-pressure chronic ulcers of the lower limb are represented by ICD-10-CM codes that begin with the code stem, L97— (Non-pressure chronic ulcer of lower limb, not elsewhere classified).
Before October 1, 2025, the only 4th character options for this code stem were:
- L97.1 - Non-pressure chronic ulcer of thigh
- L97.2 - Non-pressure chronic ulcer of calf
- L97.3 - Non-pressure chronic ulcer of ankle
- L97.4 - Non-pressure chronic ulcer of heel and midfoot
- L97.5 - Non-pressure chronic ulcer of other part of foot
- L97.8 - Non-pressure chronic ulcer of other part of lower leg
- L97.9 - Non-pressure chronic ulcer of unspecified part of lower leg
With only these options, there was no coding option to represent a non-pressure chronic ulcer of the shin. That changed on October 1, 2025, with the introduction of a new inclusion term for L97.2-, which is “Non-pressure chronic ulcer of shin.” With this change, non-pressure chronic ulcers of the shin will be represented by the L97.2 - codes.
All providers should be using the new ICD-10-CM code set effective October 1, 2025.
