K92.1 vs K62.5 and would you code the anemia when patient has no history of anemia and is not treated for anemia and levels is a low normal??

K92.1 vs K62.5 and would you code the anemia when patient has no history of anemia and is not treated for anemia and levels is a low normal??

This is how it presents:

ASSESMENT AND PLAN
S/P 2 ED visits for bleeding per rectum 6/18/26 and 6/23/26
As per he c/o bleeding per rectum for last 3 weeks, even without constipation, very low mild discomfort
no palpable anal tissue
no previous colonoscopy
no family h/o colon or gastric cancer
Hb remains mildly low 13.9gm > 13.4 gm nc

- Mostly hemorrhoidal or diverticular bleeding
- advised with high fiber diet and anusol hc cream
-schedule for early colonoscopy due to hematochezia with anemia

I was reading the guide lines on cco.uc/clinical-documentation-guides/anemia-blood-loss-polycythemia. That for level for hg for females is greater than 11.9 and males greater than 13.6 meets the WHO diagnostic threshold for anemia (those levels I mention) - but query provider if it's not documented as a diagnoses. I also read on nycmedicine.com anemia billing guide 2026 that low hemoglobin results does NOT Automatically support D64.9, D62 or D50.9 . Will you be getting back labs ? If so , you can for results to code it . Anyway, maybe K62.5 and z13.0 ??? My logic is because rectal bleeding (from hemorrhoids or diverticular disease etc) can cause Hematochezia. Also, I would use those only because I code for an outpatient urgent care and we send labs out .

Absolutely not. The provider did not mention anemia in his/her note. A coder may not ascertain any code based on lab values. Code the rectal bleeding only. You should never give a patient a diagnosis that has not been confirmed by a physician or QHP.
