X36.0 — Collapse of dam or man-made structure causing earth movement
X36.0 is a non-billable header ICD-10-CM code for collapse of dam or man-made structure causing earth movement. 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 X36
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above X36.0
These are not written on X36.0, but they bind it: a note on a category applies to every code beneath it. Billing X36.0 with anything listed here is a denial.
Excludes2 inherited from the categories above X36.0
Also inherited, and the opposite of Excludes1: these conditions are not part of X36.0, but a patient can have both, so you may code both.
Other codes that can never be billed with X36.0
These codes carry an Excludes1 note pointing at X36.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X36.0 alone.
Risk adjustment
X36.0 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 X36.0 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 X36.0.
- Collapse›dam or man-made structure(causing earth movement)
- Flood›collapse of man-made structure causing earth movement
- Forces of nature›dam collapse causing earth movement
- Forces of nature›structure collapse causing earth movement
- Landslide›caused by collapse of man-made structure
- Forces of nature›earth movement›caused by dam or structure collapse
- Forces of nature›flood›dam collapse

Questions about X36.0
- Is X36.0 a billable ICD-10-CM code?
- No. X36.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does X36.0 sit in the tabular list?
- External causes of morbidity (V00-Y99), in the block Exposure to forces of nature (X30-X39).
- What cannot be coded together with X36.0?
- X36.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above X36.0 (X36) and apply to it just the same.
