2026 ICD-10-CM Diagnosis Code L44.3 – Lichen ruber moniliformis
What it is
Lichen ruber moniliformis is a rare inflammatory skin disorder in the lichen planus spectrum. It is characterized by small, bead-like papules arranged in a chain or ring pattern.
Clinical signs
Typical findings include firm, flat-topped papules that may be grouped in linear, annular, or moniliform patterns. Clinical features vary; refer to documentation.
When to use this code
Use L44.3 when the provider documents lichen ruber moniliformis specifically. This code fits cases where the diagnosis is confirmed clinically or recorded in the assessment. If the note only says lichen planus or another variant, check documentation before coding.
Do not use for
Do not use this code for unspecified lichen planus or other papulosquamous eruptions. If the record does not clearly identify lichen ruber moniliformis, check documentation.
Coding tip
Code only when the exact term appears in the chart; otherwise, query for clarification.
