List of ICD-9 codes 800–999: injury and poisoning

List of ICD-9 codes 800–999: Injury and Poisoning is a comprehensive categorization within the International Classification of Diseases, Ninth Revision (ICD-9) that covers a wide range of conditions related to injuries and poisonings. This classification plays a crucial role in medical coding, allowing healthcare professionals and researchers to systematically identify and record various types of injuries and poisoning incidents. The codes are organized from 800 to 999, encompassing everything from fractures and dislocations to toxic effects of substances.

Overview

The ICD-9 codes 800–999 are divided into several sections, each focusing on different types of injuries and poisonings. These codes are essential for the documentation of medical records, health insurance claims, and epidemiological research. They facilitate the tracking of public health trends and the allocation of health resources.

Fractures (800–829)

This section includes codes for fractures of the skull, spine, and limbs. It differentiates between closed and open fractures and specifies the location of the fracture.

Dislocations (830–839)

Codes in this category cover dislocations of various joints, including the shoulder, elbow, hip, and knee. The classification distinguishes between initial and recurrent dislocations.

Sprains and Strains (840–848)

This segment includes injuries related to the overstretching or tearing of ligaments (sprains) and muscles or tendons (strains). It specifies the body part affected, such as the ankle, wrist, or back.

Intracranial Injury, Excluding Those with Skull Fracture (850–854)

This category deals with brain injuries that do not involve a fracture of the skull. It includes concussions, cerebral contusions, and traumatic brain injuries.

Internal Injury of Thorax, Abdomen, and Pelvis (860–869)

Codes in this section describe injuries to internal organs within the thorax, abdomen, and pelvis, such as the heart, lungs, liver, and spleen.

Open Wounds (870–897)

This classification covers open wounds, including cuts, lacerations, and punctures. It specifies the body part affected and differentiates between superficial injuries and those requiring more significant medical attention.

Injury to Blood Vessels (900–904)

This section includes injuries to major blood vessels, detailing the specific vessel involved and the body region affected.

Late Effects of Injuries, Poisonings, Toxic Effects, and Other External Causes (905–909)

Codes in this category are used to document the long-term effects of injuries, poisonings, and other external causes. This includes scarring, chronic pain, and other lasting impairments.

Superficial Injury; Contusion (910–924)

This segment covers minor injuries such as bruises and abrasions. It specifies the body part affected.

Burns (940–949)

Codes for burns detail the degree of the burn (first, second, or third degree) and the body part affected. This section also includes complications arising from burns.

Poisoning by Drugs, Medicinals and Biological Substances (960–979)

This category documents cases of poisoning by pharmaceuticals, over-the-counter medications, and other biological substances. It specifies the substance involved.

Toxic Effects of Substances Chiefly Nonmedicinal as to Source (980–989)

This section includes toxic effects from substances not primarily intended as medications, such as household chemicals, pesticides, and heavy metals.

Other and Unspecified Effects of External Causes (990–999)

This final category covers a range of conditions resulting from external causes not classified elsewhere, including effects of radiation, extreme temperatures, and pressure changes.
