D.C. Code § 16-2821

After an action is filed in the court against a healthcare provider alleging medical malpractice, the court shall require the parties to enter into mediation, without discovery or, if all parties agree with only limited discovery that will not interfere with the completion of mediation within 30 days of the Initial Scheduling and Settlement Conference (“ISSC”), prior to any further litigation in an effort to reach a settlement agreement. The mediation schedule shall be included in the scheduling conference order following the ISSC. Unless all parties agree, the stay of discovery shall not be more than 30 days after the ISSC.
