If a physician diagnoses “sepsis” but no mention of septicemia, and blood cultures come back negative, can you still code “Septicemia” in I2100?



When you search for septicemia in the ICD-10 coding guidelines, you are cross-referenced to see sepsis & specify the type of organism or use the unspecified code.  Therefore, if you have a physician-documented diagnosis of sepsis with supporting documentation that the diagnosis is active in the last 7 days (i.e. UTI with fever, tachycardia, an elevated WBC count and renal failure due to UTI), then you can code in I2100 per the RAI Manual.
