Oth diab w hyprosm w/o nonket hyprgly-hypros coma (NKHHC)

This code signifies a form of diabetes mellitus, other than Type 1 or Type 2, characterized by elevated blood glucose levels and increased serum osmolality, but without the severe complication of nonketotic hyperglycemic-hyperosmolar coma. It indicates a state of significant dehydration and hyperglycemia.

This code is appropriate for patients diagnosed with a specified type of diabetes (e.g., secondary diabetes due to pancreatectomy, drug-induced diabetes) who present with hyperosmolar hyperglycemia without progressing to a comatose state. Documentation should clearly indicate the underlying cause of diabetes and the presence of hyperosmolarity without NKHHC.

• Ensure documentation specifies the type of diabetes if known, as "other specified" implies a known, but not Type 1 or Type 2, etiology.
• Distinguish carefully between hyperosmolarity without coma and full-blown NKHHC, which has a separate code.
• Always sequence the underlying cause of the "other specified" diabetes first, if applicable, followed by this code.
