Minimal keratinized residual ridge mucosa

This code describes a condition where the alveolar ridge, after tooth extraction, has a significantly reduced amount of keratinized gingiva. This minimal band of attached tissue can lead to discomfort and challenges with denture retention or implant placement. It represents an anatomical deficiency rather than an inflammatory process.

Use this code when documentation explicitly states "minimal keratinized residual ridge mucosa" or similar phrasing indicating an insufficient band of attached gingiva on an edentulous ridge. This is often identified during pre-prosthetic evaluations for dentures or dental implants. Supporting documentation includes clinical examination findings and dental records noting the lack of adequate keratinized tissue.

• Differentiate from inflammatory conditions of the oral mucosa, which are coded elsewhere.
• Ensure documentation specifies "residual ridge" to distinguish from other areas of the oral cavity.
• This code may be sequenced as a primary or secondary diagnosis depending on the reason for the encounter (e.g., pre-prosthetic evaluation vs. treatment for complications arising from this condition).
