Lena Upfield: Acute blood loss anaemia

ENC-00065 · 51M · Hospital Medicine · admitted Tue Nov 10, 2026 03:47 PM · in hospital · attending Dr. Rosalind Quillan · resident Dr. Camila Oyelaran

Specificity gap Criteria met Open In hospital: concurrent review Resident note awaiting attending cosign

Documented “anemia” (D64.9); criteria support the more specific Acute blood loss anemia (D62).

Documented vs supported

Documented
“anemia” · D64.9 Anemia, unspecified
Criteria support
Acute blood loss anemia · D62 Acute posthemorrhagic anemia
Outcome
Haemoglobin fell 2.9 g/dL to 10.7 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
D64.9 -> D62
Secondary-diagnosis level
non-CC → CC
MS-DRG (illustrative)

Relative weight

Codes before

Codes after
J18.9, E43, N18.9, I50.30, R09.02, D62

All open gaps on this encounter together: MS-DRG 193 → 193 (RW +0.0000). The grouping does not change; the record becomes accurate.

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.
