Question:

CS Extension--Head & Neck: If a 2 cm left tonsil primary extends to the lateral aspect of the soft palate, should extension be coded to 40 [Soft palate, inferior surface including uvula or soft palate NOS] or 42 [Soft palate, superior (nasopharyngeal) surface] for a tonsil primary?

Discussion:

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.

Extension code 40 is for extension from the tonsil to the back (lower) part of the soft palate, or soft palate, NOS. Code 42 is for extension to the front (higher, nasopharyngeal surface) part of the soft palate.

Inferior soft palate is the back (lower) part of the soft palate (C051). Superior soft palate is the front, (nasopharyngeal surface) of the soft palate (C113).

Assign CS extension code 40 to the case above.
