Billable

Hypostatic pneumonia, unspecified organism

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Pneumonia that develops in dependent areas of the lungs due to fluid accumulation and poor ventilation, typically in bedridden or immobilized patients, when the causative organism is unknown.

Coding Tips

  • Hypostatic pneumonia is associated with immobility; document patient's mobility status for clinical context
  • Often seen in hospitalized or long-term care patients; consider if aspiration risk factors are present
