I am new to anesthesia coding. An epideral was given at time 1750-2206 for what was thought to be a vaginal delivery. Then at 2206-2338, anesthesia was given for cesarean delivery. I was condisering using 01961 along with 01967/01968. How is the time calculated in this case? 1750-2206 = 256min/15min = 18 units; 2206-2338 = 92min/15min =7 units. Can someone assist me in the best way to code this scenario?? Thank you in advance!!
