About coding vesicular stomatitis
The ICD-10-CM code for vesicular stomatitis is K12.1 (Other forms of stomatitis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K12.1.
Within K12, choose K12.1 (Other forms of stomatitis) only when documentation doesn't support a more specific option: recurrent oral aphthae (K12.0), cellulitis and abscess of mouth (K12.2) and oral mucositis (ulcerative) (K12.3).
Don't report K12.1 together with the conditions in its Excludes1 note: acute necrotizing ulcerative stomatitis (A69.1) and Vincent's stomatitis (A69.1).
Use an additional code to identify: alcohol abuse and dependence (F10.-), exposure to environmental tobacco smoke (Z77.22), exposure to tobacco smoke in the perinatal period (P96.81), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31) and 2 more.
