There are multiple ways to find the OWA 2013 patch or build level:

(Invoke-WebRequesthttps://owa01/op/servicebusy.htm).Headers
- On Office Web Apps server
Get-Content "C:\ProgramData\Microsoft\OfficeWebApps\Data\local\OfficeVersion.inc"
On an Office Web Apps Server, check the OfficeVersion.inc file located here
C:\ProgramData\Microsoft\OfficeWebApps\Data\local\OfficeVersion.inc
You can also check the X-OfficeVersion header value right from the browser. Please head over to my colleague Tom's blog post here.
