CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

X36 is a non-billable ICD-10-CM category code for avalanche, landslide and other earth movements, so it cannot be submitted on claims. Use a more specific code from this category instead, such as X36.0XXA, X36.0XXD, X36.0XXS, and X36.1XXA.

Specific Coding for Avalanche, landslide and other earth movementsOverview

Non-specific codes like X36 require more characters. Use one of these billable codes instead:

  • X36.0 for Collapse of dam or man-made structure causing earth movement

  • X36.1 for Avalanche, landslide, or mudslide

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to X36: its own notes plus those printed at Chapter 20. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • victim of mudslide of cataclysmic nature

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • earthquake (X34)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

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

Notes

General instructions on how these codes are used.

From Chapter 20 (V00-Y99) External causes of morbidity and mortality applies to 7,461 codes
  • This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category X36
Values for category X36 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Excludes2 2

These codes carry an Excludes2 note naming X36: its condition is not part of those codes, and both may be reported when the patient has both.

  • Block V00-V99 Transport accidents
    transport accidents due to cataclysm (X34-X38) names X34-X38, which includes this code
  • Block W65-W74 Accidental non-transport drowning and submersion
    accidental drowning and submersion due to cataclysm (X34-X39) names X34-X39, which includes this code

Code First 1

These codes say to code first a condition named in the note, and X36 is one of the conditions named.

  • W20 Struck by thrown, projected or falling object
    cataclysm (X34-X39) names X34-X39, which includes this code

Use Additional Code 1

These codes say to use an additional code from the note, and X36 is one of the codes named.

  • T71.21 Asphyxiation due to cave-in or falling earth
    code for any associated cataclysm (X34-X38) names X34-X38, which includes this code

Questions About X36Overview

What is the ICD-10 code for avalanche, landslide and other earth movements?

X36 is the ICD-10-CM category for avalanche, landslide and other earth movements, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is X36 (Avalanche, landslide and other earth movements) a billable code?

No. This is a category header that groups the codes for avalanche, landslide and other earth movements, and headers cannot be submitted on claims. Claims for avalanche, landslide and other earth movements need a more specific code from this category, such as X36.0XXA, X36.0XXD, and X36.0XXS.

Can X36 be reported with X34?

Not as a rule. The Excludes1 note on X36 lists "earthquake (X34)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
