X37.8 — Other cataclysmic storms
X37.8 is a non-billable header ICD-10-CM code for other cataclysmic storms. 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.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category X37

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.

Risk adjustment
X37.8 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.
