Question:
MP/H Rules/Histology--Vulva: How is histology coded for VIN III with focal invasion? See Discussion.
Discussion:
Per SINQ 20000442, the histology for CIN III with microinvasion is coded to 8077 [squamous intraepithelial neoplasia, grade III] per the matrix system rules, with a behavior code of /3 [malignant]. Coding the histology to 8077/3 per the matrix principle causes IF25_3 and MorphICDO3_P1 edits to fail. Flagging the first error resolves any reporting issue. How is the MorphICDO3_P1 edit resolved?
Answer:
Assign 8076/3 [squamous cell carcinoma, microinvasive] for VIN III with focal invasion. This applies to all terminologies listed under 8077/2. The SINQ question from 2000 will be retired.
