Hypertrophy of tongue papillae

This code represents an abnormal enlargement or overgrowth of the small, nipple-like projections (papillae) on the surface of the tongue. This condition can affect various types of papillae, leading to changes in the tongue's texture and appearance. It is generally a benign finding, though it can sometimes be associated with underlying systemic conditions or local irritants.

Use this code when documentation explicitly states hypertrophy of the tongue papillae, such as in cases of black hairy tongue (lingua villosa nigra) or benign migratory glossitis (geographic tongue) where papillary changes are a prominent feature. Supporting documentation should clearly describe the papillary overgrowth or enlargement.

• Differentiate from other tongue conditions like glossitis (inflammation of the tongue) unless papillary hypertrophy is specifically noted.
• Consider any associated symptoms or underlying causes documented, as these may require additional coding.
• Ensure the documentation specifies "hypertrophy" of the papillae, not just a general description of the tongue's appearance.
