How to Apply an Existing Prepayment

At times you may receive a payment that is more than the balance due from the payer. Once you create a voucher for the payment, whatever you do not use will remain on the voucher as undistributed funds. Any time you like, you can apply undistributed funds in a new Credit entry.

After selecting the payer and Credit Type (check, in the example below), clicking the Check field will show any existing check vouchers with undistributed amounts. In this case, there is such a check, so we can select it and apply any or all of the available $100 instead of creating a new check voucher.


It works exactly the same way for other types of payments (Cash, Credit Card, or Other) .

Reversing an Unapplied Payment

First, locate the credit containing the unapplied payment:

  1. Open the patient from Patients – Billing or Patients – All Data.
  2. Click to select the Ledger tab. The Ledger list tab has its own tabs. Make sure you are on the All Items tab of the Ledger list.
  3. All the Credit transactions are highlighted in green. Scan through the values in the Unapplied Amount column to find the desired transaction. You may find it helpful to click the column title a time or two to put the non-zero amounts at the top of the list. Once you find what you are looking for, double-click that line to open the Credit details view.
  4. At the top of the Credit screen, select the reason you are making this change.
  5. Next, simply change the number in the Credit Amount field, eliminating the unapplied portion. For example, if the credit amount is $100, and $60 of that has been applied, you will see $40 in the Amount Unapplied field just below Credit Amount. Subtracting $40 from $100 leaves $60, which is how much has already been applied. So, in this example, you would change the Credit Amount to $60. Doing so will automatically change the Unapplied Amount in the following field to zero. Note that this change will return $40 to the payment voucher, making that $40 available for to make a payment to any of this payer’s accounts or for refunding to the payer (see below).

Reversing an Applied Payment

  1. Open the relevant Credit in the patient’s Ledger.
  2. At the top of the Credit screen, select the reason you are making this change.
  3. Double-click each of the Credit Splits in the Credit Splits list at the bottom of the window. Change the split amount to zero and save.
  4. Once you have changed all the credit splits to zero, change the Credit Amount to zero in the upper part of the Credit screen.
  5. Save and exit the Credit. The original amount of the credit will be returned to the Voucher as undistributed funds.

Recording a Refund

If you want to refund the payer for the amount you just reversed, be sure to record it using the procedure detailed in the How to Record a Refund article.

What is the Difference Between Unapplied and Undistributed Payments

Entering Payers for Patient Accounts

There are two basic types of payers in SOS: Insurance and Non-Insurance payers.

Non-Insurance Payers

Examples of common non-insurance payers include:

  • The patient herself when the patient is an adult.
  • A parent or guardian when the patient is a child.
  • An attorney for certain types of forensic referrals.
  • A governmental or non-governmental agency that has accepted financial responsibility for treatment or evaluation costs.

You can detail any number of non-insurance payers on a single patient account. Furthermore, you can divide the non-insurance balance among them. For instance, you could name both of a child patient’s divorced parents as payers and specify that any amounts due should be divided 50-50 between them.

SOS also allows you to name the same non-insurance payer for more than one patient. You could, therefore, add a parent as a Non-Insurance Payer, then designate the parent as a payer on the accounts of each of the parent’s children. For details on adding and managing Non-Insurance Payers, see the article: Managing Patient Non-Insurance Payers.

Insurance Payers

Insurance payers in SOS are called Carriers. Each Carrier has one or more Insurance Plans. To link an Insurance Carrier and Plan to a particular patient, you add a new “Insurance Policy” to the patient, naming the desired Insurance Carrier/Plan on the Policy screen. See the article: Managing Patient Insurance Payers (Policies).

Managing Billing Providers (Suppliers)

In older versions of SOS, “Billing Providers” were known as “Suppliers”. They represent business entities that bill and collect money. In the case of a provider, working alone without a surrogate legal entity such as a corporation, LLC, PA, or partnership, the Billing Provider might be the same as the person who actually renders patient care. Current day healthcare delivery in the United States, however, more often involves some sort of legal/financial entity, and in SOS that entity is the Billing Provider. It is the name on the bank account into which your fees are deposited. To generate insurance claims or patient statements, you will have to define at least one Billing Provider.

Expand Billing Lookups in the navigation bar on the left side of your screen and select Billing Providers (Suppliers).

From this list, you can add an new Billing Provider, or view, modify, or delete (if not already in use) any entry already in the list.

Create a new Billing Provider

As with other list views in SOS, to add a new item you can click the “New” icon in the upper left of the toolbar, press the <CTRL><N> key combination, or right click to select New from the pop-up menu. You will then see the Billing Provider form. Once complete, the form will look something like the example below. Note particularly that there is a panel on the form in which you can customize the “letterhead” that SOS will print at the top of your patient billing statements. In addition to the name of the organization to be paid, you can include any other information you would like to display there. It is generally a good idea to include the billing department contact information. On some SOS statement formats this information can be adjusted to print in the upper window of a dual window envelope, in which case you would adjust the text and layout appropriately. If you are using pre-printed letterhead for your statements, then you would normally leave these fields blank.

One note regarding the Pay-To Provider panel on this screen: When generating insurance claims, you will notice an option in which you can force the data entered in this panel to replace the default data for a specific claim run.

On the bottom of this form are several tabs. The currently-selected Communications tab allows you to add addresses, phone numbers, and emails if you wish. (Adding items to an SOS Communications list is detailed in an article about Patient Communications if you need the specifics.)

Of particular significance, however, is the second tab, Carrier Specific ID’s. From time to time an organization may have to use a different identifier when sending claims to a particular payer. You can add an entry on the Carrier Specific ID’s tab if you have that situation in your organization. For example, perhaps your state’s Medicaid program requires that claims be filed using your Medical Director’s NPI, rather than the organization NPI that you normally use. SOS will automatically use the default information from the main form above, except when creating claims for the insurance payer specified in your Carrier Specific ID configuration.

Posting Your Daysheet

In SOS, the Daysheet is the screen that shows a list of recently created charge and credit entries which you have not yet committed to the permanent record. You can, for example, still delete entries while they are in the Daysheet. When you “post” a Daysheet, however, you make the designated entries a permanent part of your accounting and they can no longer be deleted. Until you post, the items in the Daysheet window are not included in billing runs or in accounting reports such as the all-important aging reports. How often you post daysheets is entirely up to you. You can post several times a day, or wait two or more days before posting. It is important, however, that you understand the following:

  • Items on the current daysheet do not appear in statements or insurance claims.
  • Items on the current daysheet do not appear in most accounting and management reports.

When you decide to post, you can post every transaction in the Daysheet, or just select specific transactions to be posted. You can even post a single transaction if you like.

Selecting transactions for posting

Before you start the posting process, tag (highlight) one or more rows in the Daysheet list. There are several specific icons that appear in the main toolbar at the top of the SOS screen while you are working on the Daysheet:

Left to right: Tag all transactions, un-tag all transactions, print the selected transactions, post the selected transactions.
  • First, keep in mind that the Daysheet is a list like most others in SOS, so you can easily filter the list by specifying values in one or more columns at the top of the list. For example, you can specify a particular patient name at the top of the Patient column, a particular provider at the top of the Provider column, or a particular user at the top of the Added By column. Doing so will immediately hide all rows that do not match your filter conditions. You can then selectively highlight the desired transactions using the following techniques.
  • If you want to print or post everything in the Daysheet, use the Tag All button (third button of the four shown in the image above).
  • If you want to print or post a group of consecutive transactions, click the first one to highlight that one, then hold down the <SHIFT> key and click the last one in the group to highlight everything in between.
  • If you want to print or post more than half of the transactions, first highlight the whole list using the Tag All icon, then hold down the <CTRL> key and click each of the rows you want to un-tag.
  • If you want to print or post less than half the list, you can reverse the above technique. Start by using the Un-tag All button (button four) then hold down the <CTRL> key and click the transactions you want to tag.

Preview and print the Daysheet

Once you have the desired transactions tagged, SOS suggests that you preview and optionally print a hard copy or generate a PDF of the Daysheet before posting. Click the Print Daysheet button (the second of the Daysheet buttons on the toolbar).

Daysheet Preview.

Posting the Daysheet

Once you have checked over your Daysheet preview and printed a hard copy or saved a copy as a PDF to a secure location (remember that this report contains HIPAA protected data), you are ready to post the Daysheet, moving the transactions to the permanent account ledgers. You will then be able to bill and include the data in your reports.

To post, simply click the Post Daysheet button on the toolbar. A reminder will appear. Just confirm that you want to proceed and the tagged rows will disappear from the Daysheet list. They then can be viewed and modified if necessary from the individual patient ledgers.
