Prepare all journal entries for 20X2 concerning the following data for a medical clinic that performs elective laser surgery that corrects vision. Such procedures are not covered by third-party payers such as Blue Cross or Medicare. Consider the following balances of the medical clinic on December 31, 20X1: Gross Receivables from Individual Patients, $250,000 and Allowance for Doubtful Receivables, $50,000, which makes Net Receivables $200,000. During 20X2, total billings to individual patients were $2.5 million. Past experience indicated that 10% of such individual billings would ultimately be uncollectible. Write-offs of receivables during 20X2 were $240,000.
