To code weeks of gestation, start by noting the last menstrual period (LMP). Calculate the time elapsed from the LMP to the current date. Convert this period into weeks and days. Use the formula: `Gestational age (in weeks) = (Current Date - LMP) / 7`. This method is accurate if the patient has a regular menstrual cycle.
