Chronic apical periodontitis
ICD-10 K04.5 is a billable code used to indicate a diagnosis of chronic apical periodontitis.
Chronic apical periodontitis is a dental condition characterized by the inflammation of the periapical tissues surrounding the root of a tooth, typically due to a long-standing infection. Clinically, patients may present with symptoms such as persistent pain, swelling, and tenderness in the affected area, though some may be asymptomatic. The condition arises when bacteria invade the pulp of the tooth, often following dental caries or trauma, leading to necrosis of the pulp and subsequent inflammatory response in the periapical region. Anatomically, the condition involves the tooth root, surrounding alveolar bone, and periodontal ligament. Disease progression can lead to the formation of a periapical abscess or cyst if left untreated. Diagnostic considerations include clinical examination, radiographic imaging to assess bone loss, and pulp vitality tests. Treatment typically involves root canal therapy to remove the infected pulp and seal the root canal system, or extraction in severe cases. Proper diagnosis and management are crucial to prevent complications such as systemic infections.

K04.5 specifically covers chronic apical periodontitis, which may arise from untreated dental caries, trauma, or previous dental procedures leading to pulp necrosis and inflammation of the periapical tissues.
K04.5 should be used when there is clear evidence of chronic inflammation in the periapical area, particularly when symptoms persist over time, differentiating it from acute conditions or other pulp-related codes.
Documentation should include clinical findings, radiographic evidence of periapical changes, treatment notes, and any relevant patient history indicating the chronic nature of the condition.
