Primary lacrimal gland atrophy, right lacrimal gland

This code signifies a degenerative reduction in the size and function of the right lacrimal gland, which is responsible for tear production. This atrophy is considered primary, meaning it's not secondary to another identifiable disease process or injury. The condition can lead to dry eye symptoms due to insufficient tear film.

Apply this code when documentation explicitly states primary atrophy of the right lacrimal gland. This diagnosis is typically made after ruling out secondary causes of lacrimal gland dysfunction, such as autoimmune diseases (e.g., Sjögren's syndrome), infection, or trauma. Documentation should support the primary nature of the atrophy.

• Differentiate from secondary lacrimal gland atrophy, which would require an additional code for the underlying cause.
• Ensure laterality is clearly documented (right, left, bilateral, or unspecified) to select the most specific code.
• Do not confuse with lacrimal gland hypoplasia (underdevelopment) or aplasia (absence), which are congenital conditions.
