ICD-9-CM is the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States. The ICD-9 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started.
ICD-9-CM codes are very different than ICD-10-CM/PCS code sets: There are nearly 19 times as many procedure codes in ICD-10-PCS than in ICD-9-CM volume 3. There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM. ICD-10 has alphanumeric categories instead of numeric ones.
The GEMs are a tool you can use to convert data from ICD-9-CM to ICD-10-CM and ICD-10-PCS and vice versa. The GEMs are also known as crosswalks as they provide important information linking codes of one system with codes in the other system.
On October 1, 2013, the ICD-9 code sets will be replaced by ICD-10 code sets. The U.S. Department of Health and Human Services issued a final rule on January 16, 2009, adopting ICD-10-CM (clinical modifier) and ICD-10-PCS (procedure coding) system.
However, most ICD-9-CM codes are still matched with multiple terms in ICD-10-CM, and there is still room for double billing during the period when the two systems will be activated simultaneously.
Combination Codes: single code used to identify two diagnoses, or a diagnosis with a secondary process or manifestation, or a diagnosis with an associated complication.
The GEMs are a tool that can be used to convert data from ICD-9-CM to ICD-10-CM and PCS and vice versa. Mapping from ICD-10-CM and PCS codes back to ICD-9-CM codes is referred to as backward mapping. Mapping from ICD-9-CM codes to ICD-10-CM and PCS codes is referred to as forward mapping.
Video: Crosswalking Crosswalking is the mapping of equivalent or near-equivalent codes between two different code sets. The most important type of crosswalking today is between ICD-10-CM and ICD-9-CM.
General Equivalence Mappings or GEM as it is popularly called comes into use if you are looking to translate lists of codes, coded data or code tables while converting a system or any other application containing ICD-9-CM.
This tool allows you to convert ICD-9-CM codes to their equivalent ICD-10-CM codes. The conversion tool is powered by the ICD-9-CM General Equivalency Mapping (GEM), a crosswalk between the two code standards which is maintained by the Center for Medicare Services and the CDC.
Objective-On October 1, 2015, the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) replaced ICD-9-CM (Ninth Revision) as the diagnosis coding scheme for the U.S. health care system.

To help you prepare for the Oct. 1 implementation of ICD-10, EyeNet is providing an overview of the five-step process for finding ICD-10 codes (see below), along with a series of subspecialty-specific Savvy Coders, starting next month with cataract. You’ll Need These Two Lists. Before you get started, you’ll need access to two sets of lists.
Contact with and (suspected) exposure to unspecified communicable disease 1 Z20.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 2 Short description: Contact w and exposure to unsp communicable disease 3 The 2021 edition of ICD-10-CM Z20.9 became effective on October 1, 2020. 4 This is the American ICD-10-CM version of Z20.9 - other international versions of ICD-10 Z20.9 may differ.
The 2022 edition of ICD-10-CM Z20.9 became effective on October 1, 2021.

In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.

854.00 is a legacy non-billable code used to specify a medical diagnosis of intracranial injury of other and unspecified nature without mention of open intracranial wound, unspecified state of consciousness. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
The following crosswalk between ICD-9 to ICD-10 is based based on the General Equivalence Mappings (GEMS) information:
Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death.
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
Most ICD-9 codes are three digits to the left of a decimal point and one or two digits to the right of one. For example:
ICD codes are also used in clinical trials to recruit and track subjects and are sometimes, though not always, included on death certificates. 4
Having the right code is important for being reimbursed for medical expenses and ensuring the standardized treatment for your medical issue is delivered.
When your doctor submits a bill to insurance for reimbursement, each service is described by a common procedural technology (CPT) code, which is matched to an ICD code. If the two codes don't align correctly with each other, payment may be rejected.
ICD codes are used globally to track health statistics and causes of death. This is helpful for gathering data on chronic illnesses as well as new ones. For example, a new code was added to the ICD-10 in 2020 to track vaping-related illnesses. 3
The 10th version of the code, in use since 2015, is called the ICD-10 and contains more than 70,000 disease codes. 1 The ICD is maintained by the World Health Organization (WHO) and distributed in countries across the globe.
The ICD receives annual updates in between revisions, which is sometimes reflected in the code title. For example, the 2020 updated version is the ICD-10-CM. The ICD-11 was approved by the WHO in 2019 and goes into effect in 2022. 2
