Income Taxes	3 Months Ended
Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes. Our provision for income taxes for the three-month periods ended March 31, 2020 and 2019 was a tax expense of approximately $1.2 million and $651,000, respectively, which resulted in an effective tax rate of (58.3)% and 9.5%, respectively. The increase in the income tax expense and the corresponding change in the effective income tax rate for the three-month period ended March 31, 2020, when compared to the prior-year period, was primarily due to discrete expenses related to the fair value adjustment of the contingent consideration liabilities of recent equity acquisitions and the write-off of our purchase option to acquire Bluegrass Vascular Technologies, Inc. (“Bluegrass Vascular”) due to our decision not to exercise our option to purchase this business (see Note 14).

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
