Employee Savings Plan [Abstract]
Employee Savings Plan	12. Employee Savings Plan The terms of the amended and restated Progenics Pharmaceuticals 401(k) Plan (the Amended Plan), among other things, allow eligible employees to participate in the Amended Plan by electing to contribute to the Amended Plan a percentage of their compensation to be set aside to pay their future retirement benefits. We matched 50% of employee contributions equal to 1%-10% of compensation during the year ended December 31, 2015 and 50% of employee contributions equal to 5%-8% of compensation during the two years ended December 31, 2014, made by eligible employees to the Amended Plan (the Matching Contribution). In addition, we may also make a discretionary contribution each year on behalf of all participants who are non-highly compensated employees. We made Matching Contributions of approximately $327, $276 and $330 to the Amended Plan for 2015, 2014 and 2013, respectively. No discretionary contributions were made during those years.
