Malignant neoplasm of pyriform sinus
Chapter 2:Neoplasms
ICD-10 C12 is a billable code used to indicate a diagnosis of malignant neoplasm of pyriform sinus.
C12 refers to malignant neoplasms located in the pyriform sinus, a part of the oropharynx situated on either side of the larynx. These tumors are often associated with squamous cell carcinoma, which is the most common histological type found in this region. The pyriform sinus is particularly vulnerable to carcinogenic factors, including tobacco and alcohol use, and more recently, human papillomavirus (HPV) has been implicated in the pathogenesis of oropharyngeal cancers. Patients may present with symptoms such as dysphagia, odynophagia, hoarseness, and referred otalgia. Diagnosis typically involves imaging studies like CT or MRI, and biopsy for histological confirmation. Treatment often includes a combination of surgery, radiation therapy, and chemotherapy, depending on the stage and location of the tumor. Radiation therapy is particularly critical in managing these tumors, especially in cases where surgical resection is not feasible. The prognosis varies significantly based on the tumor's stage at diagnosis and the patient's overall health, with HPV-positive tumors generally having a better prognosis than HPV-negative ones.
Detailed pathology reports, treatment plans, and follow-up notes are essential.
Management of newly diagnosed patients, treatment planning, and follow-up for recurrence.
Ensure accurate coding of HPV status and treatment modalities.
Surgical notes, imaging studies, and pre-operative assessments are critical.
Surgical interventions for tumor resection and management of complications.
Document the extent of resection and any adjuvant therapies.
Used for initial evaluation of suspected pyriform sinus tumors.
Document findings and any biopsies performed.
Otolaryngologists should ensure thorough documentation of the procedure.
Used for patients receiving radiation therapy for C12.
Document treatment plans and patient responses.
Oncologists must detail the radiation fields and doses.
HPV status is crucial as it influences treatment decisions and prognosis. Accurate documentation of HPV status is necessary for coding and can affect the patient's treatment plan.
C12 specifically refers to malignant neoplasms of the pyriform sinus. Ensure that the documentation clearly states the tumor's location and histology to avoid confusion with other codes.
