Partial laryngectomy (hemilaryngectomy) performed via a horizontal approach.
Modifiers may be applicable depending on circumstances. For example, modifier 51 may be used for multiple procedures, modifier 22 for increased procedural services, or modifier 52 for reduced services.
Medical necessity for a horizontal partial laryngectomy is established by the presence of a lesion in the supraglottic larynx that requires surgical removal to prevent airway obstruction, treat malignancy, or address a significant benign condition.
The surgeon is responsible for all aspects of the procedure, including pre-operative assessment, tracheostomy, making the horizontal incision, excising the diseased tissue, reconstruction, and closure.Anesthesiologist and other support staff may also be involved.
In simple words: The doctor removes part of the voice box (larynx) using a horizontal cut. Before the main surgery, a small tube is placed in the windpipe to help the patient breathe. The surgeon then makes a cut in the neck, removes the diseased part of the voice box, and stitches everything back together.
This procedure involves the surgical removal of a portion of the larynx through a horizontal incision.A tracheostomy is typically performed prior to the main procedure to ensure the patient's airway remains open.The surgeon makes a horizontal incision at the sternocleidomastoid muscles, then incises the cartilage covering the larynx to excise diseased tissue.Reconstruction is completed using the anterior neck muscles, and the incision is closed with sutures.
Example 1: A 65-year-old male presents with a T1N0M0 supraglottic squamous cell carcinoma.A horizontal partial laryngectomy is performed to remove the tumor with clear margins. , A 70-year-old female with a T2N1M0 supraglottic carcinoma has failed prior radiotherapy.A salvage horizontal partial laryngectomy is performed to remove residual disease., A 50-year-old male presents with a large benign lesion in the supraglottic larynx causing significant airway compromise.A horizontal partial laryngectomy is performed to remove the lesion.
