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:
- 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.
- 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.
