- Definition Amount of revenue recognized during the period for providing services to patients, primarily on an inpatient or outpatient basis and from office visits. For financial reporting purposes, patient service revenue is reflected net of provisions for contractual allowances (the amount needed to reduce the entity's gross billing rates to agreed-upon rates in contracts with third-party payers) and other adjustments. Significant revenue earned under capitation arrangements is reported separately. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Audit and Accounting Guide (AAG) -Number AAG-HCO -Chapter 8 -Paragraph 10 -IssueDate 2006-05-01 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
