ICD-10-CM 2027
ICD-10 code for furuncle
From the official ICD-10-CM alphabetic index entry “Furuncle”. Page updated September 29, 2026.
About coding furuncle
The ICD-10-CM code for furuncle is L02.92 (Furuncle, unspecified). The official index lists 45 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L02.92.
Within L02.9, choose L02.92 (Furuncle, unspecified) only when documentation doesn't support a more specific option: cutaneous abscess, unspecified (L02.91) and carbuncle, unspecified (L02.93).
Use an additional code to identify organism (B95-B96).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
