What are the classifications of burns? Burns are classified as first-, second-, or third-degree, depending on how deep and severely they penetrate the skin's surface. First-degree (superficial) burns First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example.
Burns are categorized by percentage of body area. For example, âhe has a second-degree burn over 30 percent of his bodyâ is a common way to describe a burn. Percentages are determined using âThe Rule of Nines,â and knowing this rule is essential for CPTÂ® and ICD-9-CM coding of second-degree and higher burns.
