How much is a HIPAA fee for medical records?

I'm curious to know, what exactly is the cost associated with acquiring medical records under the Health Insurance Portability and Accountability Act, or HIPAA? Is there a standard fee that healthcare providers typically charge for this service, or does it vary depending on the nature of the request or the provider's individual policies? And, are there any potential exceptions or exemptions to this fee, perhaps for patients seeking their own records or for certain types of requests?
