J34.8212

Billable

External nasal valve collapse, dynamic

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

What This Code Means

This condition occurs when the outer wall of the nose collapses inward during breathing, particularly when air is being inhaled, causing nasal obstruction. This dynamic collapse happens because the nasal structure lacks sufficient support to maintain its shape during the breathing process.

Coding Tips

  • •Verify documentation specifies 'dynamic' collapse (occurring during breathing) versus 'static' collapse to ensure correct code selection, as J34.8211 is used for static external nasal valve collapse
  • •Confirm laterality is documented (right, left, or bilateral) as the fifth character (2=bilateral shown in this code) must match the clinical documentation
