Chronic periodontitis.

Coding should accurately reflect the severity and extent of the periodontitis.Appropriate modifiers may be used to indicate the complexity of the procedure performed.

Modifiers may be used to indicate the location, extent, and complexity of the periodontal treatment.Specific modifier usage should follow current coding guidelines.

Medical necessity for treatment of chronic periodontitis is established by the presence of progressive periodontal disease, impacting the supporting structures of the teeth.Treatment is necessary to prevent further bone loss, tooth mobility, and ultimately tooth loss.The severity of the disease dictates the extent of the required treatment.

Diagnosis and treatment of periodontal disease;This includes periodontal examination, charting, scaling and root planing, and other periodontal procedures as needed.Referral to a periodontist may be necessary for more complex cases.

IMPORTANT:Consider additional codes to specify contributing factors such as alcohol abuse, tobacco use, or other systemic conditions.

In simple words: Chronic periodontitis is a gum disease that causes inflammation and damage to the gums and bones supporting your teeth.If not treated, it can lead to tooth loss.

Chronic periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone.It's characterized by progressive destruction of these tissues, leading to tooth loss if left untreated.Various factors contribute to its development, such as poor oral hygiene, genetic predisposition, and systemic conditions.

Example 1: A 45-year-old male patient presents with bleeding gums, gingival recession, and deep periodontal pockets.Radiographic examination reveals bone loss.Diagnosis: Chronic periodontitis., A 60-year-old female patient with a history of diabetes mellitus is experiencing persistent inflammation and loosening of teeth. Examination shows significant bone loss and purulent exudate from periodontal pockets. Diagnosis: Chronic periodontitis, complicated by diabetes., A 28-year-old patient presents with chronic gingivitis that has progressed to moderate chronic periodontitis, with evidence of bone loss on radiographs.The patient reports poor oral hygiene habits.Diagnosis: Chronic periodontitis.
