Code Description

ICD-10 K04.02 is a billable code used to indicate a diagnosis of irreversible pulpitis.

Key Diagnostic Point:

Irreversible pulpitis is a dental condition characterized by inflammation of the dental pulp that is not reversible. Clinically, it presents with severe, persistent pain that may be spontaneous or provoked by thermal stimuli. The anatomy involved includes the dental pulp, which is the innermost part of the tooth containing nerves and blood vessels. Disease progression typically involves the initial stages of reversible pulpitis, where inflammation is mild and can resolve, but if left untreated, it progresses to irreversible pulpitis. This condition may lead to necrosis of the pulp and subsequent complications such as abscess formation. Diagnostic considerations include a thorough clinical examination, patient history, and diagnostic tests such as percussion tests, thermal tests, and radiographic evaluation to assess the extent of pulp involvement and rule out periapical pathology. Treatment usually involves endodontic therapy (root canal treatment) or extraction, depending on the tooth's condition and patient factors.

ICD-10 Improvements

Irreversible pulpitis significantly impacts patient quality of life due to pain and potential complications. It is a common dental condition that can lead to increased healthcare utilization, including emergency visits and surgical interventions. Understanding the epidemiology of this condition can help in developing preventive strategies and improving overall dental health outcomes in the population.

Frequently Asked Questions

What specific conditions are covered by K04.02?

K04.02 specifically covers irreversible pulpitis, which may arise from untreated dental caries, trauma, or extensive dental procedures. It is characterized by severe pain and potential complications like pulp necrosis or abscess formation.

When should K04.02 be used instead of related codes?

K04.02 should be used when the clinical presentation indicates irreversible pulpitis, as evidenced by persistent pain and diagnostic findings. It is differentiated from K04.01, which is used for reversible pulpitis where the pulp can recover.

What documentation supports K04.02?

Documentation should include a detailed patient history, clinical examination findings, diagnostic test results, and treatment plans. Radiographs showing pulp involvement and any associated periapical pathology should also be included.
