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.
An egg is released into the fallopian tubes once a month to await fertilization. If a sperm reaches the egg and penetrates it, it is fertilized. Conception takes place during ovulation. This happens 2 weeks after the last day of your last menstrual cycle. If eggs are not fertilized, they are released through menstruation and process repeats next month.
