ICD-10 PROS, TIPS and ICD 9 Comparison table

International Classification of Diseases (ICD-10)

ICD-10 was endorsed by the Forty-third World Health Assembly in May 1990 and came into use in World Health Organization (WHO) Member States as from 1994. WHO's original intent for ICD was as a statistical tool for the international exchange of mortality data. A subsequent revision was expanded to accommodate data collection for morbidity statistics. On January 1, 1999 U.S. implemented for mortality statistics (death certificates). Actually is being used by the following countries for reimbursement or Case Mix;

• United Kingdom (1995)

• Nordic countries (Denmark, Finland, Iceland, Norway,

   Sweden) (1994 – 1997)

• France (1997)

• Australia (1998)

• Belgium (1999)

• Germany (2000)

• Canada (2001)

PROS

Right now, even with the less precise codes, the codes help drive research on the quality, cost, accessibility and outcomes of health services. They also help identify trends in care.

• Reimbursement – would enhance accurate payment for services rendered
• Quality – would facilitate evaluation of medical processes and outcomes
• Flexible enough to quickly incorporate emerging diagnoses and procedures
• Exact enough to identify diagnoses and procedures precisely
• Incorporates much greater specificity and clinical information, which results in
• Improved ability to measure health care services
• Increased sensitivity when refining grouping and reimbursement methodologies
• Enhanced ability to conduct public health surveillance
• Decreased need to include supporting documentation with claims
• Provides detailed information on procedures
• Ample space for capturing new technology and devices
• Logical structure with clear, consistent definitions

TIPS

It is complex. Compared with the 15,000 diagnostic codes in the current system there will now be 70,000. The number of codes for inpatient hospital procedures—now totaling in at 4,000—will spike to 72,000. Many of the codes will not be needed on a regular basis (like V97.33CD, which indicates you were sucked into a jet engine, and this is your subsequent visit to a doctor). The average medical office probably won’t need more than 40 to 50 ICD codes for diagnosis, by this time you should have selected the most used codes for your practice. You can also select the most appropriate codes by the population you serve. (Ex. High population with HBP, DM, etc.)

TIP # 1 Identify the most used codes for your practice.

TIP # 2 Look for specific codes/category within every ICD-10 sections.

TIP # 3 Start dual coding until you are familiar with the most used ICD-10 codes.
