Inquiry Details
References:
2007 MP/H Rules
Question:
MP/H Rules/Histology/Ambiguous terminology: Can synonyms of listed terms, such as "variety" for the list termed "type," be used to code a more specific histology? See Discussion.
Discussion:
The list of terms denoting a more specific histology does not include "variety." During MP/H training sessions there was an emphasis placed on only using terms listed to code a more specific histology. However, the results of an audit indicated that because "variety" is a synonym for "type" it could be used to code a more specific histology. Are synonyms of listed terms to be used to code histology?
Answer:
No. Synonyms of listed words used in the MP/H rules (e.g., "variety" for the listed term "type") cannot be used to designate a more specific histology.
