Tidalwave

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

X37.41 Tidal wave due to earthquake or volcanic eruption (also a header)
X37.42 Tidal wave due to storm (also a header)
X37.43 Tidal wave due to landslide (also a header)

This code requires a seventh character. See the rule below.
