Cutaneous abscess, furuncle and carbuncle (L02) ICD-10-CM
The L02 code range covers cutaneous abscess, furuncle and carbuncle with 106 ICD-10-CM diagnosis codes. 81 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the L02 range.
Abscess
Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.
Carbuncle
An infection of cutaneous and subcutaneous tissue that consists of a cluster of boils. Commonly, the causative agent is STAPHYLOCOCCUS AUREUS. Carbuncles produce fever, leukocytosis, extreme pain, and prostration.
Furuncle
Bacterial infection of the hair follicle and the surrounding skin. It is caused by Staphylococcus aureus. It presents as a painful, erythematous and swollen skin lesion.
About the L02 Code Range
Skin abscesses, furuncles, and carbuncles appear in the group for infections of the skin and tissue beneath it.
The subdivisions first separate them by site: face, neck, trunk, buttock, limb, hand, foot, another site, or an unspecified site. Each site then splits by type. For example, L02.0 covers the face; L02.01 specifies an abscess, L02.02 a furuncle, and L02.03 a carbuncle.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added L02.237 and revised the title of L02.232 to "Carbuncle of back [any part, except buttock and flank]" (was "Carbuncle of back [any part, except buttock]").
