If possible, whenever any retirant or beneficiary shall, in writing, request the Division of Pensions to make deductions from his pension or retirement allowance for the purpose of paying premiums for the pensioner's group health insurance plan or the State Health Benefits program, the division may make such deductions and transmit the sums so deducted to the companies carrying the policies. Any such written authorization may be withdrawn by any retirant or beneficiary upon filing notice of such withdrawal with the division.
