Benign neoplasm of larynx

This code signifies the presence of a non-cancerous growth originating from the tissues of the larynx, excluding the anterior aspect of the epiglottis. These benign tumors are typically slow-growing and do not metastasize, but can cause symptoms such as hoarseness, difficulty breathing, or swallowing issues depending on their size and location within the voice box.

Apply this code when documentation clearly indicates a benign neoplastic process of the larynx, confirmed by pathology or clinical findings. This is appropriate for conditions like laryngeal papillomas, chondromas, or fibromas that are not specifically identified as polyps of the vocal cord. Supporting documentation should include pathology reports, operative notes detailing tumor excision, or imaging studies describing a benign laryngeal mass.

• Ensure the neoplasm is explicitly documented as "benign" and located within the larynx.
• Distinguish carefully from laryngeal polyps (J38.1) and benign epiglottic neoplasms (D10.5), which are excluded.
• If the specific type of benign neoplasm is known (e.g., fibroma, chondroma), consider if a more specific code within the D14 category or another appropriate category is available.
