NMPC Dental Procedure Codes

Dental treatment codes are a standardized system describing specific dental procedures and services performed by dentists in Bulgaria. The main goal of this system is to introduce a single terminology that will not only unify the descriptions of dental services in the country, but also facilitate the understanding and mutual recognition of treatments between Bulgaria and other countries in Europe.

Initially, there were about 11 dental treatment codes. However, in August 2024, they were increased and refined to 403 separate codes (with the Ordinance amending Ordinance No. 42 of 2004 on the introduction of classification statistical systems for coding diseases and health-related problems and medical procedures, published in the State Gazette, issue 69 of August 16, 2024, entering into force on January 1, 2025). This significant increase aims to ensure unambiguous, transparent and detailed designation of all performed dental interventions in one patient. This way, better control, higher quality of reporting and a more accessible information base are achieved for both medical specialists and patients.

Comprehensive oral examination

Dental check-up
Last Updated: January 1
Overview

Comprehensive assessment and documentation of the current condition of the dentition, oral cavity, and related structures of the patient. This applies to new patients, existing patients with significant changes in their condition, and existing patients who have been absent from active treatment for two or more years. The assessment may include interpretation of information obtained through additional diagnostic procedures, which should be reported and coded separately. The process includes documenting relevant oral and medical history, as well as any other pertinent information.

Frequently Asked Questions

Yes, codes are standardized and are applied equally to all patients. They reflect the procedure, not the specifics of the patient. However, always consider individual characteristics in the clinical documentation.

All codes are valid and comply with the amendments published in the State Gazette, Issue 69, dated August 16, 2024.

Use the closest code based on the description or [contact us] or your professional organization for guidance. The system is periodically updated to include newer procedures.

Yes, it is often necessary. For example, in a complete tooth restoration, there may be separate codes for diagnosis, anesthesia, filling placement, and final assessment. It is important to ensure that each code reflects the actual procedure performed.

Each system is developed based on local regulations, clinical practices, and market conditions. Some procedures are specific to a country or methodology, which leads to differences in nomenclature and the number of codes.

Can’t find the answer you’re looking for?

Not sure which code applies to your situation? Or wondering which of the two codes to use?

Describe your case in a few sentences and include some information about yourself, so we can clarify additional details if needed. Our partners at Updent - Dental cources will review your question and provide you with professional advice within 1-2 weeks – completely free of charge.

A list of updates to dental codes and sample treatments by code.

Adding additional sample treatments

January 13

Additional example treatments have been added, covering both updated and new procedures. The updated treatments include options for treating carious anterior and distal teeth, both one- and two-visit, as well as primary endodontic treatment. In addition, new protocols have been added, such as crown-on-abutment or single-crown replacement, bridgework, endodontic surgical retreatment, and non-surgical endodontic treatment, in accordance with current standards.

Added description for some of the dental codes

January 1

Descriptions have been added for certain dental codes, including their meaning and usage guidelines, to facilitate understanding and proper application.

We marked the dental codes covered by NHIF

December 21, 2024

We highlighted the dental codes covered by NHIF: 97017-00, 97017-01, 97020-00, 97300-00, 97300-01, 97301-00, 97301-01, 97311-09, 97311-10, 97311-11, 97311-12, 97546-00, 97546-01, 97546-02, 97546-03, 97710-00, 97710-01. Our goal is to make it easier to understand which codes correspond to NHIF and are covered.
