Dmitri Jessup: Acute blood loss anaemia

ENC-00125 · 49M · Cardiology · admitted Fri Nov 06, 2026 04:00 PM · discharged Mon Nov 09, 2026 02:18 PM · attending Dr. Cyrus Ellingham

Clinical validation gap Criteria met Open

Documented “acute blood loss anemia” (D62) is more specific than the criteria support (Anemia (acute blood-loss criteria not met), D64.9).

Documented vs supported

Documented: “acute blood loss anemia” · D62 Acute posthemorrhagic anemia
Criteria support: Anemia (acute blood-loss criteria not met) · D64.9 Anemia, unspecified
Outcome: Anaemia (nadir 11.2) without an acute fall or transfusion
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: D62 -> D64.9
Secondary-diagnosis level: CC → non-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: I50.9, E46, N28.9, D62, I10, E78.5, K21.9
Codes after: I50.9, E46, N28.9, I10, E78.5, K21.9, D64.9

All open gaps on this encounter together: MS-DRG 292 → 291 (RW +0.4348).

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.

DOCUMENTATION QUERY (draft)
Title: Clarification request: hematology documentation
Encounter: ENC-00125   Patient: Dmitri Jessup   To: Dr. Cyrus Ellingham

Clinical indicators from the health record:
- Documented in the record: "acute blood loss anemia" [Progress note DOC-000423]
- sex M [encounter ENC-00125]
- hemoglobin 11.64 g/dL (first) (2026-11-06 17:00) [lab LAB-004250]
- hemoglobin 11.24 g/dL (lowest) (2026-11-07 05:00) [lab LAB-004251]

Question:
The indicators above are documented in this encounter. Could you clarify the status of the documented hematologic diagnosis?

Response options (select one or write your own):
( ) Acute blood loss anemia: confirmed (please document the supporting clinical information)
( ) Acute blood loss anemia: ruled out
( ) Other explanation of the clinical findings (please specify): ____________
( ) Unable to determine

Please respond based on your independent clinical judgement. Any response, including "unable to determine", is acceptable. This query and your response are kept as part of the health record.

Other findings on this encounter

Acute kidney injury · Clinical judgement required Clinical judgement required: AKI criteria met only against a presumed baseline (no pre-admission creatinine on file).
Heart failure · Specificity gap Documented “congestive heart failure” (I50.9); criteria support the more specific Acute diastolic (HFpEF) heart failure (I50.31).
Malnutrition · Clinical judgement required Clinical judgement required: Only one consensus characteristic documented; two are required.
Acute respiratory failure · Specificity gap Criteria support Acute respiratory failure with hypoxia (J96.01); no corresponding diagnosis is documented.
