Code Description

ICD-10 K08.122 is a billable code used to indicate a diagnosis of complete loss of teeth due to periodontal diseases, class ii.

Key Diagnostic Point:

K08.122 refers to complete loss of teeth due to periodontal diseases, class II, which is characterized by significant periodontal tissue destruction leading to tooth loss. Periodontal diseases are inflammatory conditions affecting the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone. The disease progression typically begins with gingivitis, which, if untreated, can advance to periodontitis, resulting in the destruction of the periodontal attachment and bone loss. Clinically, patients may present with symptoms such as gum inflammation, bleeding, and eventual mobility of teeth. The anatomy involved includes the maxilla and mandible, where the teeth are anchored. Diagnostic considerations include clinical examinations, radiographic assessments, and periodontal probing to evaluate the extent of tissue loss. The classification of periodontal diseases is essential for determining the appropriate treatment and prognosis, with class II indicating moderate to severe attachment loss. Accurate coding is crucial for effective treatment planning and insurance reimbursement.

ICD-10 Improvements

The clinical significance of K08.122 lies in its association with systemic health issues, as periodontal disease has been linked to conditions such as diabetes and cardiovascular disease. Population health impact includes the need for preventive measures and education on oral hygiene to reduce the incidence of periodontal disease. Quality measures may focus on improving access to dental care and enhancing patient outcomes through effective management of periodontal conditions, ultimately influencing healthcare utilization patterns and reducing overall healthcare costs.

ICD-9 vs ICD-10

The clinical significance of K08.122 lies in its association with systemic health issues, as periodontal disease has been linked to conditions such as diabetes and cardiovascular disease. Population health impact includes the need for preventive measures and education on oral hygiene to reduce the incidence of periodontal disease. Quality measures may focus on improving access to dental care and enhancing patient outcomes through effective management of periodontal conditions, ultimately influencing healthcare utilization patterns and reducing overall healthcare costs.

Reimbursement & Billing Impact

Reimbursement considerations include ensuring that the treatment aligns with the diagnosis and that all necessary documentation is submitted to avoid denials. Common denials may arise from insufficient documentation or failure to demonstrate medical necessity for procedures performed. Best practices include maintaining clear records of patient assessments, treatment plans, and follow-up care to support claims.

Frequently Asked Questions

What specific conditions are covered by K08.122?

K08.122 covers complete loss of teeth specifically due to periodontal diseases classified as class II, which includes moderate to severe periodontal attachment loss and tooth mobility resulting from chronic inflammation.

When should K08.122 be used instead of related codes?

K08.122 should be used when there is complete loss of teeth due to periodontal disease, as opposed to K08.121, which is for partial loss. The distinction is critical for accurate treatment planning and reimbursement.

What documentation supports K08.122?

Documentation must include clinical findings of periodontal disease, radiographic evidence of bone loss, treatment history, and any relevant periodontal assessments to support the diagnosis of complete tooth loss.
