The term “Diabetes type 1.5” is not an official medical diagnosis recognized by the World Health Organization (WHO) or the American Diabetes Association (ADA). Instead, the term “Diabetes type 1.5” is often used to refer to a specific subtype of diabetes known as Latent Autoimmune Diabetes in Adults (LADA).
In the ICD-10 coding system, LADA is classified under E11.5, which is the code for “Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene.” This code is typically used by medical coders to identify and track cases of LADA.
However, it’s important to note that some healthcare providers may still use the term “Diabetes type 1.5” to refer to LADA, even though it’s not an official diagnosis. As a result, medical coders may encounter this term in clinical documentation and may need to clarify with the healthcare provider which ICD-10 code to use.
In summary, medical coders should use the ICD-10 code E11.5 to identify and track cases of LADA, which is sometimes referred to as “Diabetes type 1.5” by healthcare providers.
