ICD-10-PCS Procedure Codes - 4 Group
ICD-10-PCS Procedure Codes
The ICD-10 Procedure Coding System (ICD-10-PCS) is a system of medical classification used for procedural codes. The National Center for Health Statistics (NCHS) received permission from the World Health Organization (WHO), the body responsible for publishing the International Classification of Diseases to create the ICD-10-PCS as a successor to Volume 3 of ICD-9-CM and a clinical modification of the original ICD-10. The final draft was completed in 2000, but the system still has not been implemented, as the WHO has not yet set any anticipated implementation date at which to phase out ICD-9-CM.
The new procedure coding system uses 7 alpha or numeric digits while the ICD-9-CM coding system uses 3 or 4 numeric digits.The current system, International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9-CM), does not provide the necessary detail on either patients' medical conditions or on procedures performed on hospitalized patients. ICD-9-CM is 30 years old, has outdated and obsolete terminology, uses outdated codes that produce inaccurate and limited data, and is inconsistent with current medical practice. It cannot accurately describe the diagnoses and inpatient procedures of care delivered in the 21st century.
Diagnostic Information is Not Included in Procedure Description
When procedures are performed for specific diseases or disorders, the disease or disorder is not contained in the procedure code. There are no codes for procedures exclusive to aneurysms, cleft lip, strictures, neoplasms, hernias, etc. The diagnosis codes, not the procedure codes, specify the disease or disorder.
Not Otherwise Specified (NOS) Options are Restricted
ICD-9-CM often provides a "not otherwise specified" code option. Certain NOS options made available in ICD-10-PCS are restricted to the uses laid out in the ICD-10-PCS draft guidelines. A minimal level of specificity is required for each component of the procedure.
Limited Use of Not Elsewhere Classified (NEC) Option
ICD-9-CM often provides a "not elsewhere classified" code option, but because all significant components of a procedure are specified in ICD-10-PCS, there is generally no need for an NEC code option. However, limited NEC options are incorporated into ICD-10-PCS where necessary. For example, new devices are frequently developed, and therefore it is necessary to provide an "Other Device" option for use until the new device can be explicitly added to the coding system. Additional NEC options are discussed later, in the sections of the system where they occur.
Level of Specificity
All procedures currently performed can be specified in ICD-10-PCS. The frequency with which a procedure is performed was not a consideration in the development of the system. Rather, a unique code is available for variations of a procedure that can be performed.
ICD-10-PCS has a seven character alphanumeric code structure. Each character contains up to 34 possible values. Each value represents a specific option for the general character definition (e.g., stomach is one of the values for the body part character). The ten digits 0-9 and the 24 letters A-H,J-N and P-Z may be used in each character. The letters O and I are not used in order to avoid confusion with the digits 0 and 1.
The second through seventh characters mean the same thing within each section, but may mean different things in other sec-tions.
In all sections, the third character specifies the general type of procedure per-formed (e.g., resection, transfusion, fluoroscopy), while the other characters give additional information such as the body part and approach. In ICD-10-PCS, the term "procedure" refers to the complete specification of the seven characters.
