Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION	NOTE 1 – NATURE OF BUSINESS AND BASIS OF PRESENTATION We are a leading national provider of freestanding, fixed-site outpatient diagnostic imaging services in the United States based on number of locations and annual imaging revenue. At September 30, 2018, we operated directly or indirectly through joint ventures with hospitals, 305 centers located in California, Delaware, Florida, Maryland, New Jersey, and New York. Our centers provide physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders. Our services include magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), nuclear medicine, mammography, ultrasound, diagnostic radiology (X-ray), fluoroscopy and other related procedures. The vast majority of our centers offer multi-modality imaging services. Our multi-modality strategy diversifies revenue streams, reduces exposure to reimbursement changes and provides patients and referring physicians one location to serve the needs of multiple procedures. The consolidated financial statements include the accounts of Radnet Management, Inc. (or “Radnet Management”) and Beverly Radiology Medical Group III, a professional partnership (“BRMG”). BRMG is a partnership of ProNet Imaging Medical Group, Inc., Beverly Radiology Medical Group, Inc. and Breastlink Medical Group, Inc. (formerly known as Westchester Medical Group Inc.). The consolidated financial statements also include Radnet Management I, Inc., Radnet Management II, Inc., Radiologix, Inc., Radnet Managed Imaging Services, Inc., Delaware Imaging Partners, Inc., New Jersey Imaging Partners, Inc. and Diagnostic Imaging Services, Inc., all wholly owned subsidiaries of Radnet Management. All of these affiliated entities are referred to collectively as “RadNet”, “we”, “us”, “our” or the “Company” in this report. Accounting Standards Codification (“ASC”) 810-10-15-14, Consolidation, stipulates that generally any entity with a) insufficient equity to finance its activities without additional subordinated financial support provided by any parties, or b) equity holders that, as a group, lack the characteristics specified in the ASC which evidence a controlling financial interest, is considered a Variable Interest Entity (“VIE”). We consolidate all VIEs in which we are the primary beneficiary. We determine whether we are the primary beneficiary of a VIE through a qualitative analysis that identifies which variable interest holder has the controlling financial interest in the VIE. The variable interest holder who has both of the following has the controlling financial interest and is the primary beneficiary: (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. In performing our analysis, we consider all relevant facts and circumstances, including: the design and activities of the VIE, the terms of the contracts the VIE has entered into, the nature of the VIE’s variable interests issued and how they were negotiated with or marketed to potential investors, and which parties participated significantly in the design or redesign of the entity. Howard G. Berger, M.D., is our President and Chief Executive Officer, a member of our Board of Directors, and also owns, indirectly, 99% of the equity interests in BRMG. BRMG is responsible for all of the professional medical services at nearly all of our facilities located in California under a management agreement with us, and employs physicians or contracts with various other independent physicians and physician groups to provide the professional medical services at most of our California facilities. We generally obtain professional medical services from BRMG in California, rather than provide such services directly or through subsidiaries, in order to comply with California’s prohibition against the corporate practice of medicine. However, as a result of our close relationship with Dr. Berger and BRMG, we believe that we are able to better ensure that medical service is provided at our California facilities in a manner consistent with our needs and expectations and those of our referring physicians, patients and payors than if we obtained these services from unaffiliated physician groups. We contract with six medical groups which provide professional medical services at all of our facilities in Manhattan and Brooklyn, New York (“the NY Groups”). These contracts are similar to our contract with BRMG. Four of the NY Groups are owned by John V. Crues, III, M.D., RadNet’s Medical Director, a member of our Board of Directors, and a 1% owner of BRMG. Dr Berger owns a controlling interest in two of the NY Groups which provide professional medical services at one of our Manhattan facilities. RadNet provides non-medical, technical and administrative services to BRMG and the NY Groups for which it receives a management fee, pursuant to the related management agreements. Through the management agreements we have exclusive authority over all non-medical decision making related to the ongoing business operations of BRMG and the NY Groups and we determine the annual budget of BRMG and the NY Groups. BRMG and the NY Groups both have insignificant operating assets and liabilities, and de minimis equity. Through management agreements with us, substantially all cash flows of BRMG and the NY Groups after expenses including professional salaries are transferred to us. We have determined that BRMG and the NY Groups are VIEs, that we are the primary beneficiary, and consequently, we consolidate the revenue and expenses, assets and liabilities of each. BRMG and the NY Groups on a combined basis recognized $33.2 million and $32.4 million of revenue, net of management service fees to RadNet, for the three months ended September 30, 2018 and 2017, respectively, and $33.2 million and $32.4 million of operating expenses for the three months ended September 30, 2018 and 2017, respectively. RadNet recognized in its condensed consolidated statement of operations $126.8 million and $107.1 million of net revenues for the three months ended September 30, 2018, and 2017 respectively, for management services provided to BRMG and the NY Groups relating primarily to the technical portion of total billed revenue. BRMG and the NY Groups on a combined basis recognized $100.7 million and $101.4 million of revenue, net of management service fees to RadNet, for the nine months ended September 30, 2018 and 2017, respectively, and $100.7 million and $101.4 million of operating expenses for the nine months ended September 30, 2018 and 2017, respectively. RadNet recognized in its condensed consolidated statement of operations $378.7 million and $328.6 million of net revenues for the nine months ended September 30, 2018, and 2017 respectively, for management services provided to BRMG and the NY Groups relating primarily to the technical portion of total billed revenue. The cash flows of BRMG and the NY Groups are included in the accompanying consolidated statements of cash flows. All intercompany balances and transactions have been eliminated in consolidation. In our consolidated balance sheets at September 30, 2018 and December 31, 2017, we have included approximately $100.6 million and $96.3 million, respectively, of accounts receivable and approximately $14.8 million and $7.4 million of accounts payable and accrued liabilities related to BRMG and the NY Groups. The creditors of BRMG and the NY Groups do not have recourse to our general credit and there are no other arrangements that could expose us to losses on behalf of BRMG and the NY Groups. However, RadNet may be required to provide financial support to cover any operating expenses in excess of operating revenues. We also own a 49% economic interest in ScriptSender, LLC, which provides secure data transmission services of medical information. Through a management agreement, RadNet provides management and accounting services and receives an agreed upon fee. ScriptSender LLC is dependent on the Company to finance its own activities, and as such we determined that it is a VIE but we are not a primary beneficiary since we do not have the power to direct the activities of the entity that most significantly impact the entity’s economic performance. At all of our centers we have entered into long-term contracts with radiology groups in the area to provide physician services at those facilities. These radiology practices provide professional services, including supervision and interpretation of diagnostic imaging procedures, in our diagnostic imaging centers. The radiology practices maintain full control over the provision of professional services. In these facilities we enter into long-term agreements with radiology practice groups (typically 40 years). Under these arrangements, in addition to obtaining technical fees for the use of our diagnostic imaging equipment and the provision of technical services, we provide management services and receive a fee based on the value of the services we provide. Except in New York City, the fee is based on the practice group’s professional revenue, including revenue derived outside of our diagnostic imaging centers. In New York City we are paid a fixed fee set in advance for our services. We own the diagnostic imaging equipment and, therefore, receive 100% of the technical reimbursements associated with imaging procedures. The radiology practice groups retain the professional reimbursements associated with imaging procedures after deducting management service fees paid to us and we have no financial controlling interest in the radiology practices. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X and, therefore, do not include all information and footnotes necessary for conformity with U.S. generally accepted accounting principles for complete financial statements; however, in the opinion of our management, all adjustments consisting of normal recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods ended September 30, 2018 and 2017 have been made. The results of operations for any interim period are not necessarily indicative of the results for a full year. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto contained in our annual report on Form 10-K for the year ended December 31, 2017.

NATURE OF BUSINESS AND BASIS OF PRESENTATION

NOTE 1 – NATURE OF BUSINESS AND BASIS OF PRESENTATION

We are a leading national provider of freestanding, fixed-site outpatient diagnostic imaging services in the United States based on number of locations and annual imaging revenue. At September 30, 2018, we operated directly or indirectly through joint ventures with hospitals, 305 centers located in California, Delaware, Florida, Maryland, New Jersey, and New York. Our centers provide physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders.

The consolidated financial statements include the accounts of Radnet Management, Inc. (or “Radnet Management”) and Beverly Radiology Medical Group III, a professional partnership (“BRMG”). BRMG is a partnership of ProNet Imaging Medical Group, Inc., Beverly Radiology Medical Group, Inc. and Breastlink Medical Group, Inc. (formerly known as Westchester Medical Group Inc.). The consolidated financial statements also include Radnet Management I, Inc., Radnet Management II, Inc., Radiologix, Inc., Radnet Managed Imaging Services, Inc., Delaware Imaging Partners, Inc., New Jersey Imaging Partners, Inc. and Diagnostic Imaging Services, Inc., all wholly owned subsidiaries of Radnet Management. All of these affiliated entities are referred to collectively as “RadNet”, “we”, “us”, “our” or the “Company” in this report.

Accounting Standards Codification (“ASC”) 810-10-15-14, Consolidation, stipulates that generally any entity with a) insufficient equity to finance its activities without additional subordinated financial support provided by any parties, or b) equity holders that, as a group, lack the characteristics specified in the ASC which evidence a controlling financial interest, is considered a Variable Interest Entity (“VIE”). We consolidate all VIEs in which we are the primary beneficiary.

In performing our analysis, we consider all relevant facts and circumstances, including: the design and activities of the VIE, the terms of the contracts the VIE has entered into, the nature of the VIE’s variable interests issued and how they were negotiated with or marketed to potential investors, and which parties participated significantly in the design or redesign of the entity.

Howard G. Berger, M.D., is our President and Chief Executive Officer, a member of our Board of Directors, and also owns, indirectly, 99% of the equity interests in BRMG. BRMG is responsible for all of the professional medical services at nearly all of our facilities located in California under a management agreement with us, and employs physicians or contracts with various other independent physicians and physician groups to provide the professional medical services at most of our California facilities. We generally obtain professional medical services from BRMG in California, rather than provide such services directly or through subsidiaries, in order to comply with California’s prohibition against the corporate practice of medicine.

These contracts are similar to our contract with BRMG. Four of the NY Groups are owned by John V. Crues, III, M.D., RadNet’s Medical Director, a member of our Board of Directors, and a 1% owner of BRMG. Dr Berger owns a controlling interest in two of the NY Groups which provide professional medical services at one of our Manhattan facilities.

RadNet provides non-medical, technical and administrative services to BRMG and the NY Groups for which it receives a management fee, pursuant to the related management agreements. Through the management agreements we have exclusive authority over all non-medical decision making related to the ongoing business operations of BRMG and the NY Groups and we determine the annual budget of BRMG and the NY Groups. BRMG and the NY Groups both have insignificant operating assets and liabilities, and de minimis equity. Through management agreements with us, substantially all cash flows of BRMG and the NY Groups after expenses including professional salaries are transferred to us.

We have determined that BRMG and the NY Groups are VIEs, that we are the primary beneficiary, and consequently, we consolidate the revenue and expenses, assets and liabilities of each. BRMG and the NY Groups on a combined basis recognized $33.2 million and $32.4 million of revenue, net of management service fees to RadNet, for the three months ended September 30, 2018 and 2017, respectively, and $33.2 million and $32.4 million of operating expenses for the three months ended September 30, 2018 and 2017, respectively. RadNet recognized in its condensed consolidated statement of operations $126.8 million and $107.1 million of net revenues for the three months ended September 30, 2018, and 2017 respectively, for management services provided to BRMG and the NY Groups relating primarily to the technical portion of total billed revenue.

BRMG and the NY Groups on a combined basis recognized $100.7 million and $101.4 million of revenue, net of management service fees to RadNet, for the nine months ended September 30, 2018 and 2017, respectively, and $100.7 million and $101.4 million of operating expenses for the nine months ended September 30, 2018 and 2017, respectively.

The cash flows of BRMG and the NY Groups are included in the accompanying consolidated statements of cash flows. All intercompany balances and transactions have been eliminated in consolidation.

The creditors of BRMG and the NY Groups do not have recourse to our general credit and there are no other arrangements that could expose us to losses on behalf of BRMG and the NY Groups. However, RadNet may be required to provide financial support to cover any operating expenses in excess of operating revenues.

We also own a 49% economic interest in ScriptSender, LLC, which provides secure data transmission services of medical information. Through a management agreement, RadNet provides management and accounting services and receives an agreed upon fee. ScriptSender LLC is dependent on the Company to finance its own activities, and as such we determined that it is a VIE but we are not a primary beneficiary since we do not have the power to direct the activities of the entity that most significantly impact the entity’s economic performance.

At all of our centers we have entered into long-term contracts with radiology groups in the area to provide physician services at those facilities.
