The original system is covered in the article ''[[Level 4 equivalent of 2010]]''. The 2014 version (dealt with here) is superseded by the 2018 version which is dealt with in ''[[Level 4 equivalent of 2018]]''. | |||

===Additional block/levels=== | |||
Deeper cuts and the submission of additional tissue are dealt with in [[L4E rule 6 (2014)|rule 6]]. | |||
===Special stains and IHC=== | |||
Special stains and immunostains are dealt with in [[L4E rule 7-8 (2014)|rule 7 and rule 8]]. | |||
===Adjustments for micro only and teaching=== | |||
The workload is adjusted if the gross is not done by the pathologist or teaching is done as part of the sign-out. | |||
Cases where the gross is not done by the pathologist are discounted 5%. Cases that include teaching are given a 30% premium. | |||
