Dmitri Jessup: Acute respiratory failure
ENC-00125 · 49M · Cardiology · admitted Fri Nov 06, 2026 04:00 PM · discharged Mon Nov 09, 2026 02:18 PM · attending Dr. Cyrus Ellingham
Criteria support Acute respiratory failure with hypoxia (J96.01); no corresponding diagnosis is documented.
Documented vs supported
- Documented
- not documented
- 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
- add J96.01
- Secondary-diagnosis level
- — → MCC
- MS-DRG (illustrative)
- 292 Heart failure and shock with CC → 291 Heart failure and shock with MCC
- Relative weight
- 0.8490 → 1.2838 (+0.4348)
- Codes before
- I50.9, E46, N28.9, D62, I10, E78.5, K21.9
- Codes after
- I50.9, E46, N28.9, D62, I10, E78.5, K21.9, J96.01
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.

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-00125 Patient: Dmitri Jessup To: Dr. Cyrus Ellingham Clinical indicators from the health record: - SpO2 86% on room air (2026-11-06 16:20) [vital VIT-012161] - respiratory rate 33/min (2026-11-06 16:20) [vital VIT-012162] - O2 4 L/min (nasal cannula) (2026-11-06 16:30) [vital VIT-012163] Question: Based on your clinical judgement and the indicators above, can the respiratory diagnosis being evaluated and treated be further specified? Response options (select one or write your own): ( ) Acute respiratory failure with hypoxia ( ) Hypoxemia without respiratory failure ( ) Other (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).
- Acute blood loss anaemia · Clinical validation gap Documented “acute blood loss anemia” (D62) is more specific than the criteria support (Anemia (acute blood-loss criteria not met), D64.9).
- 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.
