Atrophy of tongue papillae

This code signifies a condition characterized by the wasting away or reduction in size of the small, nipple-like projections on the surface of the tongue. This atrophy can lead to a smooth, red, and often painful tongue, impacting taste sensation and oral comfort. It is often a manifestation of underlying systemic conditions or nutritional deficiencies.

Assign this code when documentation explicitly states atrophy of the tongue papillae, such as in cases of glossitis, vitamin deficiencies (e.g., B12, iron), or certain autoimmune diseases. Supporting documentation should include clinical observations of a smooth or denuded tongue surface, often accompanied by patient complaints of altered taste or discomfort.

• Differentiate from other forms of glossitis; this code specifically targets papillary atrophy.
• Always code any underlying systemic condition or nutritional deficiency as a primary diagnosis, if known, with this code as a secondary diagnosis.
• Ensure documentation clearly specifies "atrophy" of papillae, not just inflammation or other non-atrophic changes.
