 ### `MongoOperationTimeoutError`
 
-- TODO(NODE-6491): Add MongoOperationTimeoutError documentation
+The `MongoOperationTimeoutError` class represents an error that occurs when an operation could not be completed within the specified `timeoutMS`.
+It is generated by the driver in support of the "client side operation timeout" feature and inherits from `MongoDriverError`.
+When `timeoutMS` is enabled `MongoServerErrors` relating to `MaxTimeExpired` errors will be converted to `MongoOperationTimeoutError`.
