I need help with a diagnosis code. We saw a patient in the office today for follow up of a renal biopsy. His diagnosis was focal glomerulosclerosis. The pathologist also noted that "the presence of focal mild GBM thickening is indicative of early diabetic changes". This patient has never been diagnosed with diabetes. His glucose usually runs 75 - 95. He's never had a documented high or low glucose. And, he's not on any long-term medications. My physician has ordered a HgB A1C on this patient to follow up on this diagnosis. Would you just code the lab slip with V77.1 for diabetes screening? Do commercial payers cover this test?
Thanks for your input.
