You use O26.891 only when the condition is directly related to her being pregnant (and there is no other specific code that describes the condition). In other words, she would not have the condition unless she was pregnant. The ICD10 index refers you to O26.89- if the patient is insulin resistant which was caused by being pregnant. In pregnancy, insulin resistance changes with the length of the pregnancy and will increase in the later half of pregnancy whether the patient has gestational or type 2 diabetes. O99.891 refers to any condition the patient has that is complicating pregnancy, but not caused because she was pregnant (and there is no other specific code that describes the condition). In this case the index gives examples for use of this code as connective system diseases (M00-M99), diseases of the ear, mastoid process, eye, and adnexa (H codes), pelvic inflammatory disease, and peritoneal adhesions.
