Fraud and forgery go hand-in-hand. Part of the forgery statute is that someone passes a forged written instrument with the intent to defraud another person. The person passing the forged written instrument can also be charged with fraud.
For example, someone makes some form of a bogus or fraudulent documentary receipt and passes it to another person with the intent to defraud them. In that situation, they could be charged with both forgery and fraud.
