Benign neoplasm of connective and oth soft tissue of thorax

This diagnosis code signifies the presence of a non-cancerous growth originating from the connective tissues, fat, muscle, or other soft tissues within the thoracic region. These benign tumors are typically slow-growing and do not metastasize. Examples include lipomas, fibromas, or neurofibromas located in the chest wall or intrathoracic soft tissues, excluding organs.

Apply this code when documentation clearly identifies a benign neoplasm of the soft tissues of the thorax, such as a chest wall lipoma or a benign fibrous tumor of the pleura. Supporting documentation should include pathology reports confirming benignity and the specific location within the thoracic soft tissues. This code is appropriate for initial diagnosis, surveillance, or excision of such lesions.

• Carefully differentiate between benign neoplasms of the soft tissue versus benign neoplasms of thoracic organs (heart, mediastinum, thymus) due to Excludes1 notes.
• Ensure the documentation specifies "benign" and the exact location within the thorax to avoid miscoding with malignant or unspecified neoplasms.
• If the specific type of benign soft tissue neoplasm is known (e.g., lipoma), consider using a more specific code if available within the D17 category, but only if the location is explicitly thoracic soft tissue.
