Postinflammatory hyperpigmentation
ICD-10 L81.0 is a billable code used to indicate a diagnosis of postinflammatory hyperpigmentation.
Postinflammatory hyperpigmentation (PIH) is a common dermatological condition characterized by darkened areas of skin that occur following inflammation or injury. The condition arises due to an overproduction of melanin in response to skin trauma, such as acne, eczema, psoriasis, or other inflammatory skin disorders. The affected areas typically present as brown or grayish spots, which can vary in size and shape. PIH can affect individuals of all skin types but is more pronounced in those with darker skin tones due to higher melanin content. The condition is generally benign and does not pose any health risks; however, it can lead to psychological distress due to cosmetic concerns. Diagnosis is primarily clinical, based on patient history and physical examination, with no specific laboratory tests required. Differential diagnoses may include other forms of hyperpigmentation, such as melasma or lentigines, necessitating careful evaluation to ensure accurate coding and treatment planning.

L81.0 specifically covers postinflammatory hyperpigmentation resulting from various inflammatory skin conditions, including acne, eczema, and dermatitis. It does not cover hyperpigmentation from other causes, such as sun exposure or hormonal changes.
L81.0 should be used when hyperpigmentation is directly linked to a previous inflammatory process. If the hyperpigmentation is due to other factors, such as sun exposure, codes like L81.1 or L81.9 should be considered.
Documentation should include a detailed patient history of the inflammatory condition, treatment records, and any previous dermatological evaluations. Photographic evidence may also support the diagnosis.
