Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
The word "movable" does not have to be used to assign code 25. A "movable" lymph node is an involved lymph node not described as fixed or matted. The general rule is to code the lesser or lower category, which would be the case if neither movability nor fixation is mentioned. See page C-471 of the 2004 SEER Manual.
Code 25 Example: Involved lymph nodes per lymph node dissection. No mention of fixation or matting. Size of largest met within a lymph node is 4mm.
