Question:
EOD-Extension--Head & Neck: If there is no mention of vocal cord mobility, do we code indicating normal vocal cord mobility or do we code EOD-Extension to a "localized, NOS?" See discussion.
Discussion:
How do we code EOD-extension for the following tumor of the supraglottic larynx? Limited stage small cell cancer of epiglottis per discharge signout. Physical exam revealed swelling of anterior aspect of epiglottis and narrowing of epiglottis. Neck without palpable masses. Laryngoscopy with biopsy and esophagoscopy showed extensive tumor involving entire laryngeal surface of epiglottis, extending onto aryepiglottic fold, onto false vocal cords and onto left true vocal cord. Ventricle on left side was obliterated with tumor. Right true vocal cord free of tumor. There is no information regarding vocal cord mobility. Biopsy of the left true vocal cord was negative. Should EOD-extension be coded to 20 [Tumor involves more than one subsite of supraglottis without fixation or NOS] or 50 [Localized NOS]?
Answer:
For cases diagnosed 1998-2003, if vocal cord mobility is not mentioned, code as normal mobility. Code EOD-extension for the example case as 20 [Tumor involves more than one subsite of supraglottis without fixation or NOS].
