Chronic lacrimal mucocele of right lacrimal passage

This code describes a persistent, non-infectious distension of the right lacrimal sac due to an accumulation of mucus, often resulting from an obstruction of the nasolacrimal duct. It signifies a long-standing condition rather than an acute inflammatory process.

Use this code when documentation clearly indicates a chronic mucocele affecting the right lacrimal passage. This typically presents with a palpable, non-tender mass in the medial canthal region, often with epiphora, and is confirmed by imaging or clinical examination noting the chronic nature.

• Ensure documentation specifies "chronic" and "mucocele" to differentiate from acute dacryocystitis or other lacrimal sac pathologies.
• Verify laterality (right) is clearly stated in the medical record.
• Do not use for acute or unspecified lacrimal sac obstructions or inflammations.
