A condition where the lungs cannot remove enough carbon dioxide from the blood, but whether it is acute or chronic is not specified.
Buddy Insight
Respiratory failure with hypercapnia indicates the lungs cannot adequately remove carbon dioxide, leading to dangerous CO2 buildup that can cause acidosis, altered mental status, and death.

Is J96.92 an HCC code?
Yes. J96.92 (Respiratory failure, unspecified with hypercapnia) maps to Cardio-Respiratory Failure and Shock under the CMS-HCC V28 risk adjustment model (and Cardio-Respiratory Failure and Shock under V24), with a community non-dual aged RAF of 0.370. It is billable for payment year 2026.
Coder answer: J96.92 is billable and maps to V28 HCC 213, Cardio-Respiratory Failure and Shock. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. 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 J96.92
For J96.92 to 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 J96.92 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
J96.92 is the ICD-10-CM diagnosis code for respiratory failure, unspecified with hypercapnia. A condition where the lungs cannot remove enough carbon dioxide from the blood, but whether it is acute or chronic is not specified. J96.92 sits in the ICD-10-CM chapter for diseases of the respiratory system (j00-j99), within the section covering other diseases of the respiratory system (j96-j99).
Under the CMS-HCC V28 risk adjustment model, J96.92 maps to Cardio-Respiratory Failure and Shock (HCC 213) with a community, non-dual, aged base RAF weight of 0.370. Under the older V24 model, J96.92 mapped to the same category but with a base RAF weight of 0.282, 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.
Use only when respiratory failure with hypercapnia is documented but the acuity (acute vs. chronic) cannot be determined. Because J96.92 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 J96.92 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
Clinical Significance
Respiratory failure with hypercapnia indicates the lungs cannot adequately remove carbon dioxide, leading to dangerous CO2 buildup that can cause acidosis, altered mental status, and death. This condition often reflects severe COPD, neuromuscular disease, or central hypoventilation requiring ventilatory support. Accurate capture is essential for reflecting the true severity of illness in risk-adjusted populations.
Documentation Requirements
- ✓Provider documentation explicitly stating 'respiratory failure with hypercapnia'
- ✓Arterial blood gas results showing elevated PaCO2 (typically > 45 mmHg)
- ✓Clinical context including the underlying etiology causing ventilatory failure
- ✓Treatment plan including any ventilatory support (BiPAP, mechanical ventilation)
- ✓Acuity specification — whether the condition is acute, chronic, or acute-on-chronic
Commonly Confused Codes
- •J96.02: Acute respiratory failure with hypercapnia: use when acuity is clearly acute onset
- •J96.12: Chronic respiratory failure with hypercapnia: use for long-standing ventilatory failure
- •J96.22: Acute and chronic respiratory failure with hypercapnia: use for acute-on-chronic presentations
- •J96.91: Respiratory failure, unspecified with hypoxia: different gas exchange abnormality (oxygen vs. CO2)
- •R06.89: Other abnormalities of breathing: does not capture the severity of respiratory failure
