Is X36 a billable ICD-10-CM code?

No. X36 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does X36 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?

X36 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

X36 — Avalanche, landslide and other earth movements

Non-billable headerICD-10-CM

X36 is a non-billable header ICD-10-CM code for avalanche, landslide and other earth movements. 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 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

earthquake (X34)

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.

transport accident involving collision with avalanche or landslide not in motion (V01-V99)

Includes

Conditions this code covers.

victim of mudslide of cataclysmic nature

Other codes that can never be billed with X36

These codes carry an Excludes1 note pointing at X36. 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 alone.

X37.9Unspecified cataclysmic storm
X37.9XXAUnspecified cataclysmic storm, initial encounter
X37.9XXDUnspecified cataclysmic storm, subsequent encounter
X37.9XXSUnspecified cataclysmic storm, sequela
X38Flood
X38.XXXAFlood, initial encounter
X38.XXXDFlood, subsequent encounter
X38.XXXSFlood, sequela

Risk adjustment

X36 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.

Code to one of these instead X36

2 child codes. Green means billable.
