The binary millisecond radio pulsar PSR J1023+0038 exhibits manycharacteristics similar to the gamma-ray binary system PSR B1259--63/LS 2883,making it an ideal candidate for the study of high-energy non-thermal emission.It has been the subject of multi-wavelength campaigns following thedisappearance of the pulsed radio emission in 2013 June, which revealed theappearance of an accretion disk around the neutron star. We present the resultsof very high-energy gamma-ray observations carried out by VERITAS before andafter this change of state. Searches for steady and pulsed emission of bothdata sets yield no significant gamma-ray signal above 100 GeV, and upper limitsare given for both a steady and pulsed gamma-ray flux. These upper limits areused to constrain the magnetic field strength in the shock region of the PSRJ1023+0038 system. Assuming that very high-energy gamma rays are produced viaan inverse-Compton mechanism in the shock region, we constrain the shockmagnetic field to be greater than $\sim$2 G before the disappearance of theradio pulsar and greater than $\sim$10 G afterwards.
