42 CFR § 405.1037 - Discovery.
(a) General rules.
(2) The ALJ may permit discovery of a matter that is relevant to the specific subject matter of the ALJ hearing, provided the matter is not privileged or otherwise protected from disclosure and the ALJ determines that the discovery request is not unreasonable, unduly burdensome or expensive, or otherwise inappropriate.
(b) Limitations on discovery. Any discovery before the ALJ is limited.
(2) A party may not take the deposition, upon oral or written examination, of another party unless the proposed deponent agrees to the deposition or the ALJ finds that the proposed deposition is necessary and appropriate in order to secure the deponent's testimony for an ALJ hearing.
(3) A party may not request admissions or send interrogatories or take any other form of discovery not permitted under this section.
(c) Time limits.
(3) Before ruling on a request to extend the time for requesting discovery or for conducting discovery, the ALJ must give the other parties to the appeal a reasonable period to respond to the extension request.
(4) The ALJ may extend the time in which to request discovery or conduct discovery only if the requesting party establishes that it was not dilatory or otherwise at fault in not meeting the original discovery deadline.
(5) If the ALJ grants the extension request, it must impose a new discovery deadline and, if necessary, reschedule the hearing date so that all discoveries end no later than 45 calendar days before the hearing.
(d) Motions to compel or for protective order.
(1) Each party is required to make a good faith effort to resolve or narrow any discovery dispute.
(2) A party may submit to the ALJ a motion to compel discovery that is permitted under this section or any ALJ order, and a party may submit a motion for a protective order regarding any discovery request to the ALJ.
(3) Any motion to compel or for protective order must include a self-sworn declaration describing the movant's efforts to resolve or narrow the discovery dispute. The declaration must also be included with any response to a motion to compel or for protective order.
(5) The ALJ must issue and mail to each party a discovery ruling that grants or denies the motion to compel or for protective order in whole or in part; if applicable, the discovery ruling must specifically identify any part of the disputed discovery request upheld and any part rejected, and impose any limits on discovery the ALJ finds necessary and appropriate.
(e) Reviewability of discovery and disclosure rulings -
(1) General rule. An ALJ discovery ruling, or an ALJ disclosure ruling such as one issued at a hearing is not subject to immediate review by the Council. The ruling may be reviewed solely during the course of the Council's review specified in § 405.1016(e) and (f), § 405.1100, § 405.1102, or § 405.1110, as applicable.
(2) Exception. To the extent a ruling authorizes discovery or disclosure of a matter for which an objection based on privilege, or other protection from disclosure such as case preparation, confidentiality, or undue burden, was made before the ALJ, the Council may review that portion of the discovery or disclosure ruling immediately.
(iii) The ALJ determines the length of the stay under the circumstances of a given case, but in no event must the length of the stay be less than 15 calendar days beginning after the day on which the ALJ received notice of the party or non-party's intent to seek Council review.
(iv) Where CMS requests the Council to take review of a discovery ruling or where the Council grants a request, made by a party other than CMS, to review a discovery ruling, the ruling is stayed until the time the Council issues a written decision that affirms, reverses, modifies, or remands the ALJ's ruling.
(v) With respect to a request from a party, other than CMS, for review of a discovery ruling, if the Council does not grant review or take own motion review within the time allotted for the stay, the stay is lifted and the ruling stands.
(f) Adjudication period. If an adjudication period applies to the appeal in accordance with § 405.1016, and a party requests discovery from another party to the hearing, the adjudication period is extended for the duration of discovery, from the date a discovery request is granted until the date specified for ending discovery.
