Understand ICD-10-CM Rules When No Diagnosis Is Found

Question: Which diagnosis codes would we use for a visual field (VF) test to rule out the possibility of glaucoma if the results revealed no definitive diagnosis?

Answer: Because the results of the VF tests were negative — they did not confirm glaucoma or any condition — you should report the signs and symptoms that prompted the exam, link the diagnosis code(s) to the applicable VF code, and include any additional observations from the VFs in the office notes.
