Definitions from the National Library of Medicine for conditions coded in the Q39 range.
Esophageal Web

About the Q39 Code Range
These conditions affect the food pipe and are present at birth. Some also involve a connection to the windpipe.
The first subdivisions distinguish atresia, where the food pipe does not form an open passage, with or without a fistula, an abnormal connection. Q39.0 has no fistula, Q39.1 has one, and Q39.2 identifies a fistula without atresia.
Other subdivisions identify narrowing, a web, widening, or a pouch in the food pipe. Q39.8 identifies other malformations, while Q39.9 leaves the malformation unspecified.
