Acne (L70) ICD-10-CM
The L70 code range covers acne with 9 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

About the L70 Code Range
ICD-10 code L70 covers various types of acne, a common skin condition characterized by inflamed or clogged hair follicles. These codes help specifically identify the form of acne for accurate medical classification and treatment documentation.
This section includes L70.0 Acne vulgaris, known by terms like juvenile acne, cystic acne, and comedonal acne, describing typical inflammatory acne on the face. L70.1 Acne conglobata refers to a severe form featuring nodules and cysts, also called nodulocystic acne or acne fulminans. L70.2 Acne varioliformis is associated with scalp folliculitis and bacterial infections. Tropical or hydration-related acne is classified under L70.3 Acne tropica. L70.4 Infantile acne codes acne appearing in infants, sometimes called neonatal acne. L70.5 Acne excoriee identifies acne worsened by scratching or picking. Other specialized forms like occupational or steroid-induced acne fall under L70.8 Other acne. When no specific type is determined, L70.9 Acne, unspecified is used. Familiarity with these synonyms and distinctions ensures precise coding for conditions ranging from simple comedones to complex cystic acne.
