Esme Kestrel: Acute blood loss anaemia
ENC-00007 · 83M · Hospital Medicine · admitted Fri Nov 06, 2026 05:48 PM · discharged Mon Nov 09, 2026 10:47 AM · attending Dr. Odette Galloway
Specificity gap Criteria met Open
Criteria support Acute blood loss anemia (D62); no corresponding diagnosis is documented.
Documented vs supported
- Documented
- not documented
- Criteria support
- Acute blood loss anemia · D62 Acute posthemorrhagic anemia
- Outcome
- Haemoglobin fell 3 g/dL to 9.9 with 2 unit(s) transfused and a documented bleeding source
- Rule
- Acute blood loss anaemia v2026.11-1
- Published source
- WHO guideline on haemoglobin cutoffs to define anaemia in individuals and populations (2024), Adult cut-offs: men <13 g/dL, non-pregnant women <12 g/dL (unchanged from 2011) · source (checked 2026-11-14)
- Contested
- There is no published clinical definition of "acute blood loss anaemia". This rule is a LOCAL CONVENTION: WHO anaemia threshold at the nadir, a documented bleeding source, and an acute fall of >=2 g/dL OR >=2 units transfused (borrowed from the ISTH major-bleeding definition, which secondary restatements word inconsistently as AND/OR).
Effect if the clinician agrees (illustrative)
- Change
- add D62
- Secondary-diagnosis level
- — → CC
- MS-DRG (illustrative)
- 194 Simple pneumonia and pleurisy with CC → 194 Simple pneumonia and pleurisy with CC
- Relative weight
- 0.8059 → 0.8059 (+0.0000)
- Codes before
- J18.9, I50.22
- Codes after
- J18.9, I50.22, D62
All open gaps on this encounter together: MS-DRG 194 → 193 (RW +0.5085).
CC/MCC status, CC exclusions (subset) and relative weights from the public CMS FY2026 IPPS final rule tables (5, 6I, 6J, 6K). This is not a grouper and not a payment estimate. Queries never mention any of this.

SIMULATED: Illustrative severity weights (MCC = 1.0, CC = 0.5, non-CC = 0) summed over secondary diagnoses; not a validated risk-adjustment model and not a measured effect.

“black tarry stools”
Show the quote in the note… d with community-acquired pneumonia. Chest x-ray shows right lower lobe pneumonia; blood cultures drawn and ceftriaxone started. Hospital course complicated by black tarry stools.
Past medical history: heart failure with reduced ejection fraction.
Review of systems otherwise negative.
Exam: Lungs: clear to auscultation bilaterally.
