The International Classification of Disease tenth revision Procedure Coding System (ICD-10-PCS) is a system of medical classification used for procedural codes that track various health interventions taken by medical professionals.
The PCS is published by the World Health Organization to track international morbidity and mortality statistics in a comparable way. The system uses three to seven digit alphanumeric codes to specify medical procedures. The first digit indicates the section of medical practice (surgery, administration, measuring and monitoring, etc.) and the following digits specify the body system, root operation, body part, approach and the device used. The seventh character is a qualifying digit. The crucial first three digits of a code are stored in the ICD manual for reference. For example, a code beginning in 0C0 would be a medical/surgical procedure on the mouth or throat – specifically, an alteration.
The ICD-10 replaced the ninth revision of the system in 1993 and the ICD-10-PCS is a clinical modification of the original ICD-10. ICD-10-PCS codes must be used on all HIPAA transactions, starting in October 2013.
