Zara Penhallow: Acute respiratory failure
ENC-00156 · 71F · Hospital Medicine · admitted Wed Nov 11, 2026 07:38 PM · in hospital · attending Dr. Gideon Zeller
Specificity gap Criteria met Open
In hospital: concurrent review
Documented “hypoxia” (R09.02); criteria support the more specific Acute respiratory failure with hypoxia (J96.01).
Documented vs supported
- Documented
- “hypoxia” · R09.02 Hypoxemia
- Criteria support
- Acute respiratory failure with hypoxia · J96.01 Acute respiratory failure with hypoxia
- Outcome
- Hypoxaemia criterion met with a sign of respiratory distress
- 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
- R09.02 -> J96.01
- Secondary-diagnosis level
- non-CC → MCC
- MS-DRG (illustrative)
- 690 Kidney and urinary tract infections without MCC → 689 Kidney and urinary tract infections with MCC
- Relative weight
- 0.8095 → 1.1603 (+0.3508)
- Codes before
- N39.0, R09.02, K21.9, I10, E78.5
- Codes after
- N39.0, K21.9, I10, E78.5, J96.01
All open gaps on this encounter together: MS-DRG 690 → 689 (RW +0.3508).
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.

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.
