Question:

CS Extension--Lung: Chest CT shows segmental atelectasis (CS EXT code 40), but patient had Left Lower Lobe lobectomy/Lymph Node dissection with no involvment outside the lobe (pleura and all margins neg). Do we still code the atelectasis (CS Ext 40) over confined to lung (CS EXT code 10)?

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.Assign CS Extension code 40 [Atelectasis/obstructive pneumonitis that extends to the hilar region but does not involve the entire lung (or atelectasis/obstructive pneumonitis, NOS)].

CS extension code 10 does not apply when any condition described in codes 20-80 exists.
