Code Description

ICD-10 K05.322 is a billable code used to indicate a diagnosis of chronic periodontitis, generalized, moderate.

Key Diagnostic Point:

Chronic periodontitis, generalized, moderate, is a prevalent inflammatory condition affecting the supporting structures of the teeth, primarily the gums and bone. Clinically, it presents with symptoms such as gum inflammation, pocket formation, and loss of attachment, which can lead to tooth mobility and potential loss if untreated. The disease progresses through stages, beginning with gingivitis and advancing to chronic periodontitis, characterized by deeper periodontal pockets and more significant attachment loss. The anatomy involved includes the periodontal ligament, alveolar bone, and gingival tissue. Diagnosis is typically made through clinical examination, probing depths, and radiographic evaluation to assess bone loss. Factors such as plaque accumulation, genetic predisposition, smoking, and systemic conditions like diabetes can exacerbate the condition. Early detection and intervention are crucial to prevent further periodontal destruction and maintain oral health.

Frequently Asked Questions

What specific conditions are covered by K05.322?

K05.322 specifically covers moderate chronic periodontitis that is generalized, affecting multiple teeth and characterized by moderate attachment loss and probing depths.

When should K05.322 be used instead of related codes?

K05.322 should be used when the condition is generalized and moderate in severity, distinguishing it from localized forms or other severities of periodontitis.

What documentation supports K05.322?

Documentation should include clinical findings from periodontal examinations, probing depths, radiographic evidence of bone loss, and treatment plans that reflect the severity and extent of the disease.
