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.
Implantation: The fertilized egg attaches to the lining of the uterus and pregnancy begins. Most eggs are fertilized by sperm while still in the fallopian tube. The fertilized egg then travels down the fallopian tube into the uterus. This can take 1 â 2 days. When the egg reaches the uterus, it may attach itself to the uterine lining (the endometrium) and pregnancy will begin.
