(a) Where documents, including electronic media, are to be offered into evidence, copies shall be served on all adverse parties no later than the mandatory settlement conference, unless good cause is shown.

After receipt of a printout of benefits, another such request may not be made more frequently than once in a 120-day period unless there is a change in indemnity payments or a new dispute requiring updated payment periods.

(d) The parties are not required to serve a lien claimant with medical reports unless ordered by the Workers' Compensation Appeals Board, unless the lien claimant is defined as a "physician" by Labor Code section 3209.3 or is an entity described in Labor Code sections 4903.05(d)(7) and 4903.06(b), and has requested such service.
