Odette Elsworth: Acute respiratory failure
ENC-00108 · 63F · Cardiology · admitted Mon Nov 02, 2026 09:24 AM · discharged Tue Nov 10, 2026 04:49 PM · attending Dr. Jalen Carrow · resident Dr. Greta Kowalczyk
Clinical validation gap Criteria not met Open
Documented “acute hypoxic respiratory failure” (J96.01) but the criteria are not met: No hypoxaemia on room air (lowest SpO2 93%), oxygen no more than 2 L/min, no advanced support.
Documented vs supported
- Documented
- “acute hypoxic respiratory failure” · J96.01 Acute respiratory failure with hypoxia
- Criteria support
- criteria not met
- Outcome
- No hypoxaemia on room air (lowest SpO2 93%), oxygen no more than 2 L/min, no advanced support
- Rule
- Acute hypoxic respiratory failure v2026.11-1
- Published source
- Merck Manual Professional Version: Acute Hypoxemic Respiratory Failure (AHRF), including ARDS (2026), Definition/evaluation: PaO2 <60 mmHg, PaO2/FiO2 <300, or SpO2 <88%, with dyspnea and tachypnea · source (checked 2026-11-14)
- Contested
- Organizations use different oxygen-saturation cut-offs (SpO2 <88%, <=90% or <91% on room air). This rule uses <88% (the source above) and a LOCAL respiratory-rate cut-off of 28/min as one sign of respiratory distress.
Effect if the clinician agrees (illustrative)
- Change
- remove J96.01
- Secondary-diagnosis level
- MCC → removed
- MS-DRG (illustrative)
- 291 Heart failure and shock with MCC → 292 Heart failure and shock with CC
- Relative weight
- 1.2838 → 0.8490 (-0.4348)
- Codes before
- I50.22, E66.811, N17.9, J96.01, L89.152, I10, E78.5
- Codes after
- I50.22, E66.811, N17.9, L89.152, I10, E78.5
All open gaps on this encounter together: MS-DRG 291 → 292 (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.
Severity documentation index change SIMULATED
-1.0 points
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: respiratory documentation Encounter: ENC-00108 Patient: Odette Elsworth To: Dr. Jalen Carrow Clinical indicators from the health record: - Documented in the record: "acute hypoxic respiratory failure" [Progress note DOC-000365] - SpO2 93% on room air (2026-11-02 09:44) [vital VIT-010458] - respiratory rate 21/min (2026-11-03 09:44) [vital VIT-010467] - O2 2 L/min (nasal cannula) (2026-11-02 17:49) [vital VIT-010462] Question: The indicators above are documented in this encounter. Could you clarify the status of the documented respiratory diagnosis? Response options (select one or write your own): ( ) Acute hypoxic respiratory failure: confirmed (please document the supporting clinical information) ( ) Acute hypoxic respiratory failure: 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 validation gap Documented “acute kidney injury” (N17.9) but the criteria are not met: KDIGO creatinine and urine-output criteria not met.
- Heart failure · Specificity gap Documented “chronic systolic heart failure” (I50.22); criteria support the more specific Acute on chronic systolic (HFrEF) heart failure (I50.23).
- Hyponatraemia · Specificity gap Criteria support Hyponatraemia (moderate) (E87.1); no corresponding diagnosis is documented.
