K05.229

What This Code Means

This code describes a severe gum disease where the patient's immune system aggressively attacks the tissues supporting the teeth throughout the mouth, but the specific severity level is not documented. This condition can lead to tooth loss if left untreated.

Coding Tips

• •Verify documentation specifies 'generalized' (affecting multiple teeth) rather than localized periodontitis, as this distinction is critical for accurate coding
• •If severity is documented in the clinical record (mild, moderate, or severe), use the appropriate fifth character (0, 1, or 2) instead of 9 for unspecified severity
