According to the usual interpretation, your results indicate adrenal insufficiency because the ACTH should get your cortisol up to at least double your baseline level at 60 min. and yours is less than that. The stress of the test may have caused your baseline to be higher than the previous baseline, which was low. That right there indicates a problem. I would take your results to a different endocrinologist if this one doesn't believe there is anything wrong. ???
Thank you for the response. I have been finding a ton on conflicting info regarding test interpretation. I just read an article stating:
"Standard high-dose ACTH stimulation test — A serum cortisol value of 20 µg/dL (550 nmol/L) or more at any time during the test, including before injection, is indicative of normal adrenal function .
*** Criteria that require a minimum increment in serum cortisol  are invalid , because patients who have a high basal serum cortisol concentration, due either to normal circadian rhythmicity or acute stress, may be nearly maximally stimulated and unable to increase cortisol secretion further. In addition, approximately 20 percent of normal subjects with high-normal basal serum cortisol concentration have little or no rise after ACTH. It is therefore important to obtain both baseline and post-ACTH samples for accurate assessment of adrenal function."***
According to that I would be 100% fine. I just don't know who/what to believe anymore.
