Poikiloderma vasculare atrophicans

This code represents a rare, chronic, progressive skin condition characterized by a distinctive triad of atrophy, telangiectasias, and dyspigmentation (hypo- and hyperpigmentation). It is considered a cutaneous T-cell lymphoma (CTCL) precursor or a form of early CTCL, specifically mycosis fungoides. The skin lesions typically present as reddish-brown patches with fine wrinkling and visible blood vessels.

Use this code when documentation clearly identifies a diagnosis of poikiloderma vasculare atrophicans. This diagnosis is often made based on clinical presentation and confirmed by skin biopsy showing characteristic histopathological features. It is crucial to distinguish this condition from other poikilodermatous changes.

• Ensure documentation specifies "poikiloderma vasculare atrophicans" to support this specific code, rather than general poikiloderma.
• Consider co-occurring conditions, especially other forms of cutaneous T-cell lymphoma, and code them appropriately.
• Review pathology reports for definitive diagnostic confirmation, as clinical appearance alone may not be sufficient.
