2025 ICD-10-CM code K12

Stomatitis and related lesions.

Use additional codes to specify the type and cause of stomatitis when possible for improved clinical accuracy and appropriate reimbursement.

Medical necessity is established by the presence of symptomatic oral lesions causing pain, discomfort, or functional impairment.The necessity of specific treatments depends on the severity, cause, and associated complications.

Diagnosis and treatment of oral lesions. This may involve clinical examination, diagnostic tests (e.g., cultures, biopsies), and appropriate management strategies (e.g., topical medications, systemic therapy).

IMPORTANT:Additional codes may be required to specify the etiology (e.g., K12.0 for recurrent oral aphthae, K12.1 for other forms of stomatitis,and codes for specific infections or other contributing factors).

In simple words: This code describes inflammation or sores in the mouth.The exact cause needs to be determined and might be something like an infection, injury, medication, or other illness.A more detailed code might be needed to explain why this is happening.

K12 encompasses stomatitis and related lesions of the oral cavity.This includes various inflammatory conditions affecting the mucous membranes of the mouth, potentially caused by factors such as infections, trauma, medications, or systemic diseases.Further specification using additional codes might be necessary to clarify the underlying cause or contributing factors, such as alcohol abuse, tobacco use, or exposure to irritants.

Example 1: A patient presents with multiple small, painful ulcers on the tongue and buccal mucosa, consistent with recurrent aphthous stomatitis (K12.0).The physician performs a clinical examination, diagnoses the condition, and recommends a topical analgesic and anti-inflammatory treatment., A patient undergoing chemotherapy experiences severe mucositis (K12.31) characterized by inflammation and ulceration of the oral mucosa.The oncologist manages the symptoms using supportive care measures, including topical anesthetic rinses and pain medication., A patient develops stomatitis as a side effect of a newly prescribed medication.The physician documents the medication-induced stomatitis (K12.32), discontinues or alters the medication, and provides symptomatic relief measures.

Complete history and physical examination focusing on oral findings.Documentation of the location, size, appearance, and duration of the lesions.If applicable, documentation of causative factors (e.g., medication, infection, trauma), relevant laboratory test results (e.g., cultures), and treatment provided.

** K12 is a broad code encompassing various conditions. Accurate coding requires detailed clinical documentation to differentiate between specific types of stomatitis and identify contributing factors.
