There is a discussion between coders at our location that coding for facility surgery charges, you should be listing all chronic conditions. Camp A is of the opinion the ICD-10 diagnosis codes can only be pulled directly from the surgical note. Camp B is of the opinion ICD-10 diagnosis codes can be pulled from the H&P, problem list, medication list, and nursing notes to name a few. No guidelines have been found for strictly facility ICD-10 coding guidelines. These are all outpatient cases being discussed. Outpatient surgery and Observation cases. Any help, guidance, or guidelines on this topic would be greatly appreciated!
