Other insulin resistance

This code represents various forms of insulin resistance that are not specifically classified elsewhere. It indicates a condition where the body's cells do not respond effectively to insulin, leading to elevated blood glucose levels despite adequate or even high insulin production. This can be a precursor to type 2 diabetes or a component of other metabolic disorders.

Use this code when documentation specifies insulin resistance that doesn't fit a more specific ICD-10-CM code, such as those for metabolic syndrome or specific genetic syndromes. Examples include idiopathic insulin resistance, or insulin resistance identified through laboratory testing without a clear underlying etiology classified elsewhere. Documentation should clearly state "insulin resistance" and exclude more specific forms.

• Do not use this code if a more specific code for insulin resistance (e.g., E88.810 for metabolic syndrome with insulin resistance) is available and supported by documentation.
• Always sequence this code after any underlying or associated conditions, such as obesity or polycystic ovarian syndrome, if applicable.
• Ensure documentation differentiates this "other" form of insulin resistance from insulin resistance due to drug-induced diabetes or other secondary causes, which would be coded differently.
