Start with EEOC-CVG-2003-1 "May an employer require an individual to go to a health care professional of the employer's (rather than the employee's) choice for purposes of documenting need for accommodation and disability? The ADA does not prevent an employer from requiring an individual to go to an appropriate health professional of the employer's choice if the individual provides insufficient information from his/her treating physician (or other health care professional) to substantiate that s/he has an ADA disability and needs a reasonable accommodation. " Note - I'm not aware of this being common because employees will generally be better off having their own doctor release their own records or respond to employers questions about medical condition. Again, records are limited to the specific issue and need for accommodation / functional issues etc.
