Hyperosmolar Hyperglycemic State ICD-10-CM Codes

What hyperosmolar hyperglycemic state ICD codes can I use?

If you’re looking for hyperosmolar hyperglycemic state ICD codes to use but are having difficulty finding some, that’s because there are no ICD-10 codes that specifically mention hyperosmolar hyperglycemic state in their names. The closest you’ll find are those that say hyperglycemic-hyperosmolar coma, but the thing is, the ICD-10 codes will likely mention something like without nonketotic hyperglycemic-hyperosmolar coma (NKHHC).

But you need ICD-10 codes that are for patients who are in a hyperosmolar hyperglycemic state, and there are two ICD-10 codes that you can use for it:

1. E11.01 - Type 2 diabetes mellitus with hyperosmolarity with coma

This ICD-10 code is meant to be used on a patient confirmed to have Type 2 Diabetes Mellitus with hyperosmolarity (which means the blood has a high concentration of salt, glucose, and other substances) and is in a coma. While it doesn’t mention hyperglycemia (which means there is a high amount of glucose in the blood), you may use this since hyperosmolarity counts glucose salt and other substances.

2. E11.69 - Type 2 diabetes mellitus with other specified complications

This ICD-10 code is meant to be used on a patient confirmed to have Type 2 Diabetes Mellitus accompanied by a difficulty that doesn’t have a specific ICD-10 code. Since the hyperosmolar hyperglycemic state doesn’t have a specific ICD-10 code named after it, you can either use the code in Item 1 or this one.

Are these hyperosmolar hyperglycemic state ICD codes billable?

Yes. Both of these hyperosmolar hyperglycemic state-related ICD-10 codes are valid and billable.

Clinical information about the hyperosmolar hyperglycemic state:

When we speak of hyperosmolar hyperglycemic states, we’re speaking of a condition in which a person has a high amount of glucose, salt, and other substances. This is not good because this is a life-threatening state resulting from untreated/unmanaged Type 2 Diabetes. This can be exacerbated by infections in the body, heart attacks, neurological problems like stroke, a medication that increases fluid loss and negatively impacts the effects of insulin, and not taking diabetes management medication.

A person in a hyperosmolar hyperglycemic state will likely have the following symptoms:

• They will feel tired and nauseous
• They will feel dazed and confused
• Their mouth and tongue will become dry
• They will have a fever and may have seizures
• They might lapse into a coma 

Synonyms include:

• Hyperglycemia due to diabetes mellitus
• Hyperglycemic crisis due to diabetes mellitus
• Hyperosmolar coma due to diabetes mellitus
• Hyperosmolar coma due to type 2 diabetes mellitus
• Hyperosmolar hyperglycemic coma due to diabetes mellitus without ketoacidosis
• Hyperosmolar non-ketotic state due to diabetes mellitus
• Severe hyperglycemia due to diabetes mellitus
