Chronic gingivitis, plaque induced

This code signifies a persistent inflammation of the gingiva (gums) that is directly caused by the accumulation of bacterial plaque. It is characterized by redness, swelling, and bleeding of the gum tissue without involvement of the underlying bone or periodontal ligament. This condition is reversible with proper oral hygiene and professional intervention.

Use this code when documentation clearly indicates chronic inflammation of the gingiva due to plaque accumulation, without evidence of periodontitis. Supporting documentation would include clinical notes describing persistent gingival erythema, edema, and bleeding upon probing, specifically attributing these findings to plaque. This code is appropriate when there is no attachment loss or bone destruction.

• Differentiate from acute gingivitis (K05.00) based on the chronicity noted in the clinical record.
• Ensure documentation explicitly states "plaque-induced" to support this specific etiology.
• Do not use if there is any evidence of periodontal attachment loss or bone involvement; consider codes from K05.2-K05.6 instead.
