Equity Method Investments and Joint Ventures Disclosure [Text Block]	Note D - Medical Oncology Partners In April 2015, MOP, was formed in partnership with local physicians and other investors. MOP was established to acquire a 100% equity interest in UOMA. USNC was not a member of MOP at the time of formation as it was not able to participate due to the fact that USNC was not a physician. Nevertheless, USNC wished to eventually obtain an equity interest in MOP and loaned Dr. Jaime Lozano, the principal investor in MOP and a co-investor in FOP, $173,000 . Dr. Lozano used these funds, along with an equal amount of his own funds (a total of $345,000), to purchase a 76.67% interest in MOP. Other investors paid a further $105,000 for the remaining equity in MOP. MOP used the $450,000 of financing to acquire a 100% equity interest in UOMA. An application was filed for a waiver to allow USNC to hold an equity interest notwithstanding the physician requirement and on December 22, 2016, USNC was cleared to become a part owner of MOP. Dr. Lozano agreed to exchange half of his membership interest to USNC in settlement of the note to USNC. USNC and Dr. Lozano also agreed to share equally in providing a 5% equity interest in MOP to an additional investor as a consulting fee for services rendered in the administration of MOP and UOMA. At December 22, 2016, USNC owned 35.83% of MOP with an initial carrying value of $161,000. The Company recorded its share of losses of $12,000 for the period from December 22, 2016 to December 31, 2016, against its investment which resulted in a reduction of its equity investment to $149,000. Due to increasing costs, continued net losses since April 2015, and reliance on related party and other debt for operating cash flows, the fair value of UOMA is less than it’s carrying amount. The Company tested its investment for impairment at December 31, 2016 and determined that the investment was impaired, and an impairment loss was recorded against the entire equity balance in MOP, as well as loans from USN and USNC to MOP and UOMA. During the year ended December 31, 2021, the Company’s equity in loss of MOP was $231,000 but was not recorded due to prior losses. On December 31, 2022, MOP/UOMA sold their assets to One Care Oncology Partners, LLC for $2,060,000. USN Corona netted approximately $1.3 million from the proceeds for management fees to date. Some funds were held in escrow until post-closing adjustments were made. During the year ended December 31, 2023, the Company paid additional expenses totaling $47,000 related to the sale of MOP/UOMA. These expenses were recorded as an advance to MOP and fully impaired.
