Maryland Health - General Section 20-209

(b)   Except as otherwise provided in this subtitle, the State may not interfere with the decision of a woman to terminate a pregnancy:
(1)   Before the fetus is viable; or
(2)   At any time during the woman's pregnancy, if:
(i)   The termination procedure is necessary to protect the life or health of the woman; or
(ii)   The fetus is affected by genetic defect or serious deformity or abnormality.
(c)   The Department may adopt regulations that:
(1)   Are both necessary and the least intrusive method to protect the life or health of the woman; and
(2)   Are not inconsistent with established medical practice.
