Jun Upfield: Acute blood loss anaemia

ENC-00050 · 75F · Cardiology · admitted Sun Oct 25, 2026 02:06 PM · discharged Sun Nov 01, 2026 01:45 PM · attending Dr. Cyrus Ellingham

Specificity gap Criteria met Open

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 9.4 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): 292 Heart failure and shock with CC → 292 Heart failure and shock with CC
Relative weight: 0.8490 → 0.8490 (+0.0000)
Codes before: I50.21, N18.31, N17.9, D64.9, I10
Codes after: I50.21, N18.31, N17.9, I10, D62

All open gaps on this encounter together: MS-DRG 292 → 292 (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.
