Farah Elsworth: Acute blood loss anaemia

ENC-00088 · 71F · Hospital Medicine · admitted Sun Nov 01, 2026 03:43 PM · discharged Mon Nov 09, 2026 01:21 PM · attending Dr. Gideon Zeller · resident Dr. Greta Kowalczyk

Clinical judgement required Clinical judgement required Open

Clinical judgement required: Haemoglobin fell 1.4 g/dL without transfusion (between 1 and 2 g/dL).

Documented vs supported

Documented: “acute blood loss anemia” · D62 Acute posthemorrhagic anemia
Criteria support: no conclusion: clinical judgement required
Outcome: Haemoglobin fell 1.4 g/dL without transfusion (between 1 and 2 g/dL)
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).

Clinical judgement required. The rule does not conclude here. A CDI specialist may send an open query or dismiss the finding; nothing is proposed as fact.

Effect if the clinician agrees (illustrative)

Change: no projected change (clinician judgement)
Secondary-diagnosis level: CC → —
MS-DRG (illustrative): 378 GI hemorrhage with CC → 378 GI hemorrhage with CC
Relative weight: 0.9807 → 0.9807 (+0.0000)
Codes before: K92.2, I50.9, D62, L89.159, K21.9, I10
Codes after: K92.2, I50.9, D62, L89.159, K21.9, I10

All open gaps on this encounter together: MS-DRG 378 → 377 (RW +0.8473).

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.
