BT-10 BuyerReference

General Instructions

This announcement concerns Community Pharmacies (Private and Military), Healthcare Providers (Public and Private Entities), and Pharmaceutical Companies issuing B2G invoices to the National Organization for the Provision of Health Services (EOPYY).

In accordance with the official circular that has been communicated to us, changes will be implemented in the issuance and processing of B2G-type invoices where the recipient is the National Organization for the Provision of Health Services (EOPYY).

The BT-44 field (AccountingCustomerParty/PartyLegalEntity/RegistrationName) will always have the value 'NATIONAL ORGANIZATION FOR THE PROVISION OF HEALTH SERVICES (E.O.P.Y.Y.)'. This field will be automatically populated by the provider, and no action is required on your part.

Among the changes outlined in the circular, the only modification relevant to your operations pertains to the BT-10 field (Buyer reference).

Previously — and still applicable to other B2G cases — the BT-10 field contained the following format:

Contracting Authority Name | RecipientàRegisteredName

It is clarified that this change regarding the BT-10 field applies exclusively in cases where the Contracting Authority is EOPYY. For all other Contracting Authorities, the previously stated format remains unchanged.

However, under the new instructions, for invoices issued to EOPYY, the BT-10 field must be completed in one of the following alternative formats, depending on the final recipient of the electronic invoice:

a) EOPYY Pharmacies

For invoices issued by Pharmaceutical Companies to EOPYY Pharmacies, the BT-10 field must include the prefix:
BT-10 Prefix: PHARM

Followed by the following elements separated by hyphens (-):

The EOPYY Pharmacy Code (see Annex B for a full list)

The Order Number (if applicable; otherwise, this can be left blank and the hyphen omitted)

Example BT-10: PHARM-973-2024000001

b) e-DAPY

For invoices processed through e-DAPY, Healthcare Providers must complete the BT-10 field as follows:
BT-10 Prefix: EDAPY

Followed by (hyphen-separated):

Submission Number (no leading zeroes)

Contract Number

Example BT-10: EDAPY-580999-2024000001

c) KMES

For invoices processed by KMES, Community Pharmacies must use one of the following prefixes, depending on the invoice type:

TEES-MONTHLY (for monthly submission invoices)
TEES-OTHER (for other invoice types)

i. Monthly Submission Invoices:
BT-10 Prefix: TEES-MONTHLY

Followed by and separated by hyphens (-):

Pharmacy Contract Number (numeric, no leading spaces)

Reference Month (6 digits, YYYYMM)

Submission Month (6 digits, YYYYMM)

Submission Type (numeric, as defined in the Web Service Specifications on the EOPYY website)

Example:
Contract Number: 2012000352
Reference Month: 202408
Submission Month: 202409
Submission Type: 2
BT-10: TEES-MONTHLY-2012000352-202408-202409-2

ii. Other Invoices:
BT-10 Prefix: TEES-OTHER

Followed by and separated by hyphens (-):

Invoice Type: Currently only 1 is supported (annual credit invoices for withholding rebates)

Pharmacy Contract Number

Year applicable to the invoice

Example:
Invoice Type: 1
Contract Number: 2012000352
Year: 2024
BT-10: TEES-OTHER-1-2012000352-2024

d) Credit Invoices for Rebate and Clawback

For credit invoices related to Rebate and Clawback amounts, the BT-10 field must be completed as follows:
BT-10 Prefix: ACCT-CLAWBACK

Followed by and separated by hyphens (-):

Protocol Number of the Official Notification

Issue Date of the notification in YYYYMMDD format

e) Invoices Not Related to Health Services (e.g., office supplies, cleaning services, etc.)

For invoices unrelated to health products or services, the BT-10 field must be completed as follows:
BT-10 Prefix: ACCT-OTHEREXP

Followed by and separated by hyphens (-):

PE.DI Code (a 3-digit code representing the relevant Regional Directorate; use 000 if the invoice concerns EOPYY as a whole — see Annex A for a complete list)

With regard to the referenced annexes, as well as for further information concerning the change, please refer to the circular shared in the attached PDF file.

To support the correct population of the BT-10 field according to the new specifications, a new field named BuyerReference has been added in the B2G Details.
When this field is populated correctly — as per the specifications described above — it will fully replace the previously used content of the BT-10 field.

It is clarified that validation will be applied to the BuyerReference field to ensure that the input begins with one of the predefined prefixes corresponding to the acceptable formats described above.

We kindly request that you ensure timely adaptation, as the new requirements will take effect on June 1st, 2025. Failure to correctly populate the BT-10 field will result in invoice rejections (soft-rejects) and may cause delays and inconvenience to all involved parties.
Regarding the changes related to the configuration of your ERP system, please contact your system implementers or consultants.

Also, if you have the IMPACT Connector for SAP (SAP HELLAS) solution, you will need to contact the project implementation teams for clarifications.
