Medical coders must assign and input the correct diagnostic code to establish the amount of money a health care provider or facility gets reimbursed from the insurer. In order to maintain consistency, they must utilize standard classification systems, like ICD-9-CM/CPT/HCPCS/DRG/APC.
Sometimes a small amount of spotting or vaginal bleeding is one of the first symptoms of pregnancy. Known as implantation bleeding, it happens when the fertilised egg attaches to the lining of the uterus â about 10 to 14 days after fertilization.
Some scientists say that implantation is when and where pregnancy begins. What is implantation and are there any common signs of implantation? Implantation occurs when the egg that has been fertilized by the sperm attaches to the inner wall of the uterus about 7-9 days after conception. Having traveled down the fallopian tube and divided several times, the fertilized zygote has reached its final destination in the warm and nourishing uterine lining.
