2027 ICD-10-CM Diagnosis Code X30Exposure to excessive natural heat
X30 is a non-billable ICD-10-CM category code for exposure to excessive natural heat, so it cannot be submitted on claims. Use a more specific code from this category instead, such as X30.XXXA, X30.XXXD, and X30.XXXS.

Notes
General instructions on how these codes are used.
- 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 code X30
- Ainitial encounter
- Dsubsequent encounter
- Ssequela

Patient EducationClinical
Heat Illness
Your body normally cools itself by sweating. During hot weather, especially when it is very humid, sweating just isn't enough to cool you off. Your body temperature can rise to dangerous levels and you can develop a heat illness.

Questions About X30Overview
What is the ICD-10 code for exposure to excessive natural heat?
X30 is the ICD-10-CM category for exposure to excessive natural heat, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is X30 (Exposure to excessive natural heat) a billable code?
No. This is a category header that groups the codes for exposure to excessive natural heat, and headers cannot be submitted on claims. Claims for exposure to excessive natural heat need a more specific code from this category, such as X30.XXXA, X30.XXXD, and X30.XXXS.
Can X30 be reported with W92?
Not as a rule. The Excludes1 note on X30 lists "excessive heat of man-made origin (W92)". 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).
