  1. IF 821: Mycosis Fungoides Schema: Primary Site, CS Extension conflict

specification

The purpose of this edit is to verify that CS Extension is coded properly for the Mycosis Fungoides and Sezary Disease schema per Note  4 for CS Extension:

Use code 150 when skin involvement is present but only a general location/site is mentioned (i.e., face, legs, torso, arms). Use code 300 when there is skin involvement but there is no mention of location/site.

 

This edit is skipped if:

  1. CS Extension is empty.

  2. Behavior Code ICD-O-3 = 0 (benign) or 1 (borderline)

  3. CS schema is invalid

 

This edit first determines the correct CS schema by doing a function call to the CS Dynamic Link Library (dll). The function call passes Primary Site, Histologic Type ICD-O-3, and CS Site-Specific Factor25 (schema discriminator) to the dll and the CS schema name is returned.

 

If schema is MycosisFungoides:
