Rosacea (L71)
ICD-10 code L71 and its subcodes are specifically used to classify various forms of rosacea, a chronic inflammatory skin condition that primarily affects the face. These codes help identify different presentations of rosacea, including its most common types and related skin inflammations.
The general ICD-10 code L71 covers rosacea broadly, while L71.0 targets perioral dermatitis, a subtype characterized by irritation around the mouth often linked to factors like lip-licking or corticosteroid use. The many synonyms such as "irritant contact dermatitis of face" or "contact dermatitis caused by saliva" assist coders in mapping various clinical descriptions to this code. L71.1 denotes rhinophyma, a condition with skin thickening and enlargement of the nose, also known as phymatous rosacea. The L71.8 code captures other specified rosacea forms, including ocular rosacea and granulomatous rosacea, reflecting symptoms like eye inflammation or sebaceous gland changes. Finally, L71.9 is for unspecified rosacea, covering cases where a precise subtype is not documented but symptoms like facial flushing or rosacea-related conjunctivitis are present. Using these codes correctly ensures accurate diagnosis reporting for various clinical rosacea presentations.
Instructional Notations
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.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Rhinophyma
A manifestation of severe ROSACEA resulting in significant enlargement of the NOSE and occurring primarily in men. It is caused by hypertrophy of the SEBACEOUS GLANDS and surrounding CONNECTIVE TISSUE. The nose is reddened and marked with TELANGIECTASIS.
Rosacea
A cutaneous disorder primarily of convexities of the central part of the FACE, such as FOREHEAD; CHEEK; NOSE; and CHIN. It is characterized by FLUSHING; ERYTHEMA; EDEMA; RHINOPHYMA; papules; and ocular symptoms. It may occur at any age but typically after age 30. There are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (National Rosacea Society's Expert Committee on the Classification and Staging of Rosacea, J Am Acad Dermatol 2002; 46:584-7).
Rosaceae
The rose plant family in the order ROSALES and class Magnoliopsida. They are generally woody plants. A number of the species of this family contain cyanogenic compounds.
Rosales
An order of the class MAGNOLIOPSIDA. Its members include some of the most known ornamental and edible plants of temperate zones including roses, apples, cherries, and peaches.
