NOMESCO Classification of Surgical Procedures (NCSP) 


NOMESCO Classification of Surgical Procedures (NCSP) was developed by a Nordic working group within NOMESCO, and the first English version was published in 1996.


The Nordic countries, except Iceland, use their own translation of the English version of NCSP. Estonia uses the English version for statistics and DRG. The non-surgical procedures are national Nordic classifications, but are mapped to NCSP format and included in “NCSP-plus”, which is a cross map for mainly DRG use. Iceland uses the English version of NCSP-plus in their EHRs.



Since 1996 the Centre has been responsible for the yearly update and revision of NCSP.


Until 2012 the updates have taken place according to set procedures. Suggestions to updates were submitted to the national classification authorities in each country. All proposals concerning NCSP were reviewed and prepared by an expert advisor. Electronic discussion groups were also used. The proposals were then considered by the Nordic reference group for classifications and subject to approval by the Centre Board before final implementation.


During the recent years fewer updates have been needed. Moreover the time limits set for each Nordic country have made a common updating process difficult. The Centre Board therefore decided in 2011 that NCSP should no longer be updated on a yearly basis, but to monitor development in surgical procedures. A possible scenario could be an updated, printed version every third year, but then again, each Nordic country has annual national updates.

New, changed or deleted codes are reported to the Casemix Centre in Helsinki, to be mapped and imported in NCSP-plus.


Instructions for updates

The responsible national classification body requires the following if update proposals are to be considered:

• The proposal should include a description of the new method and an account of its indications.

• The proposal should also include a rough estimate of how many procedures that are performed per year in the country or the expected annual number in the near future.

• References should be included to relevant literature documenting that any proposed new codes represent established procedures and not purely experimental procedures.
