Question:

EOD-Pathologic Extension--Prostate: Does capsular invasion (code 32) take priority over apex extension (code 34) on prostate primaries? See discussion.

Discussion:

On prostatectomy, adenocarcinoma involves left apex and also left mid lobe where it focally invades capsule. Do we code extension to 34 - the highest numerical code, or to 32 to capture the capsular invasion? Do codes 33 and 34 represent a subset of code 31, and would code 32 represent greater tumor involvement?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Pathologic Extension field to 32 [Invasion into (but not beyond)prostatic capsule] when there is both capsular and apex invasion of the prostate.

Although numerically lower, code 32 takes precedence over codes 33 [arising in the apex] and 34 [extending to the apex]. Codes 33 and 34 are "subsets" of code 31 [Into prostatic apex/arising in prostatic apex].
