Secondary lacrimal gland atrophy, left lacrimal gland

This code describes the pathological reduction in size and function of the left lacrimal gland due to an underlying systemic or localized condition. This atrophy impairs tear production, leading to dry eye symptoms and potential ocular surface damage.

Use this code when documentation specifies atrophy of the left lacrimal gland that is secondary to another identifiable disease process, such as Sjögren's syndrome, sarcoidosis, or chronic inflammation. The medical record must clearly indicate the left eye and the secondary nature of the atrophy.

• Ensure the documentation explicitly states "secondary" atrophy and specifies the left lacrimal gland.
• Always code the underlying primary condition first, followed by this code.
• Differentiate from primary lacrimal gland atrophy (H04.14-) where no underlying cause is identified.
