Question:
Reportability/Histology--Eye: Is “squamous mucosa with high grade dysplasia” equivalent to a diagnosis of “high grade squamous dysplasia?” See Discussion.
Discussion:
A conjunctival biopsy final diagnosis is squamous mucosa with moderate to high grade dysplasia. The diagnosis comment states that immunostains were performed and confirm squamous histology. This seems to imply a high grade squamous dysplasia, rather than a non-reportable high grade dysplasia. Does this case meet the criteria for reportable high grade squamous dysplasia?
Answer:
Squamous mucosa with high grade dysplasia is the same as high grade squamous dysplasia in the conjunctiva and is coded to 8077/2.
