CplPunishment13,
I found exactly what you are looking for:
Here is the reference and pay close attention to #3, which I underlined.
MCO P1900.16F, Marine Corps Separation and Retirement Manual, Chapter 8, Separation and Retirement for Physical Disability
8607. DEPLOYABILITY/PCS
1. For Marines who are on TLD, deployability is left to the discretion of the Marine’s commanding officer, who should take into consideration the recommendations of the medical officer that dictated the MEB which placed the Marine on limited duty. TLD is intended to allow a Marine to recover from an illness/injury and return to full duty. Commanding officers should consider whether or not deploying the Marine will aggravate and worsen the illness/injury, and whether or not the Marine will be afforded adequate medical treatment where the unit is deployed, thus allowing the Marine the best opportunity to recover and return to full duty.
2. Marines on TLD should not execute PCS orders unless it can be assured that:
(a) The Marine can receive the same level of medical treatment at the new MTF as is being received at the current MTF; and
(b) Re-locating the Marine will not, in any way, aggravate or worsen the illness/injury.
3. Once a Marine has entered the DES, by way of an MEB being accepted by the PEB, the Marine shall not be deployed or execute PCS orders, unless approved by the CMC (MMSR-4).
