Volcanic eruption (X35)
This set of ICD-10 codes covers injuries and accidents directly caused by volcanic eruptions, including initial treatment, follow-up care, and long-term effects. These codes help specify the exact stage of medical care related to volcanic eruption incidents.
The primary code X35 identifies any injury from a volcanic eruption, encompassing various natural events like volcanic lightning, lava flows, mudflows, tephra falls, and pyroclastic density currents. Subcategories such as X35.XXXA mark the initial encounter with injuries caused by these volcanic activities, including urban fires and gases released during eruptions. For ongoing treatment or complications, X35.XXXD is used for subsequent encounters, while X35.XXXS indicates sequela, or long-term consequences resulting from the initial volcanic event. By referencing these codes, medical coders can accurately document conditions stemming from volcano-related accidents or environmental exposure, ensuring clear communication and proper tracking of volcanic injury cases in health records. This makes these the go-to ICD-10 codes for volcanic eruption-related injuries and their treatment phases.

Instructional Notations
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to code X35
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Atmosphere
The gaseous envelope surrounding a planet or similar body. (From Random House Unabridged Dictionary, 2d ed)
Lightning
An abrupt high-current electric discharge that occurs in the ATMOSPHERE and that has a path length ranging from hundreds of feet to tens of miles. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
Lightning Injuries
Accidental injuries caused by brief high-voltage electrical discharges during thunderstorms. Cardiopulmonary arrest, coma and other neurologic symptoms, myocardial necrosis, and dermal burns are common. Prompt treatment of the acute sequelae, including cardiopulmonary resuscitation, is indicated for survival.
Spasms, Infantile
An epileptic syndrome characterized by the triad of infantile spasms, hypsarrhythmia, and arrest of psychomotor development at seizure onset. The majority present between 3-12 months of age, with spasms consisting of combinations of brief flexor or extensor movements of the head, trunk, and limbs. The condition is divided into two forms: cryptogenic (idiopathic) and symptomatic (secondary to a known disease process such as intrauterine infections; nervous system abnormalities; BRAIN DISEASES, METABOLIC, INBORN; prematurity; perinatal asphyxia; TUBEROUS SCLEROSIS; etc.).
