We will make the following updates: A new property will be added to Account: Account.covers (Encounter, EpisodeOfCare)  0..* Definition : An account that collects the charges for a specific set of services offered over a limited time period.  For example, a hospital account might contain all charges related to a given admission, including any inpatient appointments, and possibly re-admissions, of the billing for those re-admissions should be grouped with the initial admission for the purpose of claim submission. Comment : Episode Accounts often exist for the duration of a relatively short billing cycle (for example, a month, or possibly a quarter).  One a given billing cycle ends, the associated Episodic Account would close, and a new account would open for the next billing cycle.  A patient that is admitted for 6 months, where the billing cycle is monthly, would have 6 episodic accounts each covering one month.       Encounter.account and EpisodeOfCare.account will have their comments updated to: Comment :  The billing system may choose to allocate billable items associated with the Encounter/EpisodeOfCare to different referenced Accounts based on internal business rules.  Also note that the Encounter.account/EpisodeOfCare.account properties are meant to represent long-running or perpetual accounts.  For short-lived, episodic accounts, see Account.covers.       We will add a "Notes" section in the Account resources with the following content: Perpetual and Episodic Accounts There may be two types of accounts that are used to track billing activities with medical systems: Episodic Account :  An account that collects the charges for a specific set of services offered over a limited time period.  For example, a hospital account might contain all charges related to a given admission, including any inpatient appointments, and possibly re-admissions, of the billing for those re-admissions should be grouped with the initial admission for the purpose of claim submission. Episodic Accounts often exist for the duration of a relatively short billing cycle (for example, a month, or possibly a quarter).  One a given billing cycle ends, the associated Episodic Account would close, and a new account would open for the next billing cycle.  A patient that is admitted for 6 months, where the billing cycle is monthly, would have 6 episodic accounts each covering one month. Episodic Accounts may be communicated using the Account.covers property. Perpetual   Account:   A long running account that accumulates charges and payments associated with a specific beneficiary.  This account is often open for as long as the beneficiary has a relationship with the healthcare organization.  It may be linked to an EpisodeOfCare.  A beneficiary may have different perpetual accounts.  For example, one for charges related to car crash (i.e., third party liability).  One associated with charges related to a research study the patient is participating in.  And one for their general personal/family care, which would be covered by their normal insurance. Perpetual Accounts may be communicated using the Encounter.account or EpisodeOfCare.account properties.
