Atrophy of tongue papillae

This code describes the thinning or wasting away of the small, nipple-like projections (papillae) on the surface of the tongue. This condition often results in a smooth, red, or pale appearance of the tongue, which can affect taste sensation and oral comfort. It is a sign of underlying systemic or localized issues rather than a primary disease itself.

Use this code when documentation explicitly states atrophy of the tongue papillae, often observed during an oral examination. This condition is frequently associated with nutritional deficiencies (e.g., iron, B12, folate), fungal infections (e.g., candidiasis), Sjögren's syndrome, or other systemic diseases. Documentation should specify the presence of papillary atrophy.

• Always look for an underlying cause to code concurrently, as papillary atrophy is often a symptom.
• Distinguish from other tongue conditions like glossitis (inflammation of the tongue) unless atrophy is specifically noted.
• Avoid using this code if the documentation only describes a "smooth tongue" without explicitly mentioning papillary atrophy.
