J80
BillableAcute respiratory distress syndrome
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is J80 an HCC code?
Yes. J80 maps to Cardio-Respiratory Failure and Shock under the CMS-HCC V28 risk adjustment model (and Cardio-Respiratory Failure and Shock under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for J80
For J80to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed J80 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
J80 is the ICD-10-CM diagnosis code for acute respiratory distress syndrome. A severe, life-threatening condition where the lungs fill with fluid, making it difficult or impossible to breathe and requiring immediate medical intervention. J80 sits in the ICD-10-CM chapter for diseases of the respiratory system (j00-j99), within the section covering other respiratory diseases principally affecting the interstitium (j80-j84).
Under the CMS-HCC V28 risk adjustment model, J80 maps to Cardio-Respiratory Failure and Shock (HCC 213) with a community, non-dual, aged base RAF weight of 0.000. Under the older V24 model, J80 mapped to the same category but with a base RAF weight of 0.402 — V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
This is a critical diagnosis often requiring ICU-level care; ensure it is clearly documented in the medical record. Because J80 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for J80 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a critical diagnosis often requiring ICU-level care; ensure it is clearly documented in the medical record
- •Document the underlying cause (sepsis, trauma, aspiration, etc.) with additional codes to support severity and treatment decisions
Clinical Significance
Acute Respiratory Distress Syndrome is a life-threatening condition characterized by rapid onset of widespread alveolar inflammation, capillary leak, and bilateral pulmonary infiltrates leading to refractory hypoxemia. It is one of the most resource-intensive diagnoses in medicine, typically requiring ICU admission, mechanical ventilation, and multidisciplinary care, making it highly significant for risk adjustment.
Documentation Requirements
- ✓Bilateral pulmonary infiltrates on chest imaging not fully explained by cardiac failure or fluid overload
- ✓PaO2/FiO2 ratio documenting severity (Berlin criteria: mild 200-300, moderate 100-200, severe <100)
- ✓Acute onset within 1 week of known clinical insult or new/worsening respiratory symptoms
- ✓Underlying cause documented (sepsis, pneumonia, aspiration, trauma, pancreatitis, etc.)
- ✓Mechanical ventilation parameters if intubated (PEEP settings, FiO2, tidal volumes)
- ✓ICU admission documentation and severity scoring
Excludes 1 — Do NOT code together
- respiratory distress syndrome in newborn (perinatal) (P22.0)
Commonly Confused Codes
- •J81.0 (Acute pulmonary edema) — cardiogenic vs. non-cardiogenic; ARDS is non-cardiogenic by definition
- •J96.0x (Acute respiratory failure) — respiratory failure is a broader category; ARDS is a specific syndrome
- •J18.9 (Pneumonia, unspecified) — pneumonia may cause ARDS, but they are separate diagnoses requiring separate codes
- •R06.03 (Acute respiratory distress) — symptom code only, not the syndrome; J80 requires clinical criteria
