X34Earthquake

Non-billable headerICD-10-CM

X34 is a non-billable header ICD-10-CM code for earthquake. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • tidal wave (tsunami) due to earthquake (X37.41)

Other codes that can never be billed with X34

These codes carry an Excludes1 note pointing at X34. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X34 alone.

  • X36Avalanche, landslide and other earth movements

Risk adjustment

X34 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How X34 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to X34.

  • Earthquake(any injury)
  • Forces of natureearthquake
  • Victimearthquake
  • Forces of natureearth movementearthquake
  • Struck byobjectfallingfrom, in, onearthquake

3 child codes. Green means billable.
