Irritative hyperplasia of oral mucosa

This code represents a benign, reactive overgrowth of the oral mucosal tissue due to chronic irritation. It typically manifests as a firm, often nodular or papillary lesion, resulting from factors like ill-fitting dental appliances, sharp tooth edges, or persistent biting habits.

Use this code when documentation specifies an irritative hyperplasia of the oral mucosa, excluding lesions specifically identified as denture hyperplasia of the edentulous ridge. This diagnosis is supported by clinical examination findings describing a localized, non-neoplastic tissue proliferation in response to chronic trauma or irritation within the oral cavity.

• Differentiate carefully between general oral mucosal irritative hyperplasia and hyperplasia specifically of the edentulous ridge caused by dentures (K06.2).
• Ensure documentation clearly identifies the location and nature of the hyperplasia to rule out other oral lesions.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it's an associated finding.
