An administrative law judge (ALJ) can obtain
medical expert (ME) testimony by audio, agency video, online
video, or in limited circumstances described in 20
CFR 404.936(c)(2) and 416.1436(c)(2),
in person. These methods provide the ALJ, claimant, or appointed
representative, if any, the opportunity to question the ME at the time
testimony is given. However, an ALJ can also obtain ME testimony through
written interrogatories.
Interrogatories are often used when an ALJ receives post-hearing
evidence that requires further review because it appears the additional
evidence may affect the outcome of the case. However, an ALJ can use
interrogatories at any time in the hearing process. The ALJ may obtain
interrogatories at the request of the claimant or representative, or on
the ALJ's own initiative.
