SECONDARY DIAGNOSIS (ICD) is the same as attribute CLINICAL CLASSIFICATION CODE. SECONDARY DIAGNOSIS (ICD) is the International Classification of Diseases (ICD) code used to identify the secondary PATIENT DIAGNOSIS.
In the U.S., ICD-10 is split into two systems: ICD-10-CM (Clinical Modification), for diagnostic coding, and ICD-10-PCS (Procedure Coding System), for inpatient hospital procedure coding.
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.
A: ICD-10-CM (International Classification of Diseases -10th Version-Clinical Modification) is designed for classifying and reporting diseases in all healthcare settings.
Work on ICD-10 began in 1983, became endorsed by the Forty-third World Health Assembly in 1990, and was first used by member states in 1994. It was replaced by ICD-11 on January 1, 2022. While WHO manages and publishes the base version of the ICD, several member states have modified it to better suit their needs.
The two parts of the ICD-10-CM index are the index to diseases and injury and index to external causes of injury.
A combination code is a single code used to classify 1) two diagnoses, 2) a diagnosis with an associated secondary process (manifestation), or 3) a diagnosis with an associated complication.
Combination codes may also exist that classify two diagnoses or one diagnoses with an associated complication. The diseases and injuries in the Tabular List are organized into chapters according to etiology, body system, or purpose.

The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) was developed in the United States and is used to classify morbidity (disease) data from inpatient and outpatient records, including provider-based office records.
ICD-10 -CM stands for. International Classification of Disease, Tenth Edition clinical modification.
There is no difference between ICD 10 CM and ICD 10. In fact, when most people are talking about ICD-10, they are speaking of ICD-10CM. ICD-10CM is the medical coding set for diagnosis coding and is used in all healthcare establishments in the U.S.
Which of the following is not one of the criteria that CMS uses to form a CC subclass in the MS-DRGs? Limiting the number of groups to a manageable number is not one of the criteria for determining whether a CC subclass is appropriate.
A code listed next to a main term in the ICD-10-CM Alphabetic Index is called a default code, which: • Represents the condition most commonly associated with the main term; or • Indicates that it is the unspecified code for the condition.
All health care providers use code set in U.S. health care settings. Providers document diagnoses in medical records and coders assign codes based on that documentation. CDC developed and maintains code set. Use ICD-10-CM diagnosis codes on all inpatient and outpatient health care claims.
Outpatient coding uses ICD-10-CM diagnostic codes and CPT or HCPCS codes, which specifically apply to services and supplies provided in the outpatient setting. Documentation plays a key role in assigning CPT and HCPCS codes. Inpatient coding is more complex than outpatient coding.
The codes from A00 through Z99 are always reported as first-listed diagnoses.
Section IV Diagnostic Coding and Reporting Guidelines for Outpatient Services take precedence over the general and disease specific guidelines.
Patient, with known cardiovascular disease, is seen for a follow-up visit to discuss results of a cardiac perfusion study (cardiovascular function study), which is normal.
Other Diagnosis 2: Procedure scheduled but not performed due to contraindications
There is a combination code for hypertension with end-stage renal disease. I12.0 assumes a casual relationship in this scenario. Under code I12.0 in the Tabular, a notation states "use additional code to identify the stage of chronic kidney disease (N18.5; N18.6)"
For patients receiving preoperative evaluations, sequence first a code from the subcategory Z01.81, Encounter for preprocedural examinations, followed by findings related to the preoperative evaluation.
Following outpatient surgery for a right bunionectomy for hallux valgus, the patient was admitted to observation due to an exacerbation of her asthma post procedure.
ICD-10 was implemented for mortality reporting in the U.S. in 1999
ICD-10-CM codes were developed and are maintained by CDC’s National Center for Health Statistics under authorization by the WHO.
If you utilize already-coded ICD data, you will need to learn the new codes that apply to your data and conditions of interest. See the Training for available public health-oriented training options.
You are creating a “one-to-one” applied mapping (aka crosswalk) between code sets that will be used in an ongoing way to translate records or other coded data
Currently, ICD-9-CM codes are mostly numeric and have 3 to 5 digits. ICD-10 code sets are alphanumeric and contain 3 to 7 characters. ICD-10 code sets are more robust and descriptive with “one-to-many” matches in numerous instances. There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM, and nearly 19 times as many procedure codes in ICD-10-PCS than in ICD-9-CM volume 3.
ICD-10-CM/PCS has an improved structure, capacity, and flexibility for capturing advances in technology and medical knowledge. It incorporates greater clinical detail and level of specificity to provide better quality of data for many purposes. That greater clinical detail and specificity will also allow for more efficient tracking of health care and public health trends, quality of care issues, and evaluating health outcomes.
Like ICD-9-CM codes, ICD-10-CM/PCS codes will be updated every year via the ICD-10-CM/PCS Coordination and Maintenance Committee. However, please note that a partial freeze has been implemented for ICD-10-CM/PCS and revisions will only be for new diseases/new technology procedures and any minor changes to correct reported errors. Regular updates will resume in 2015 (please go to the ICD-9-CM Coordination and Maintenance Committee page for more information).
ICD-10-CM/PCS code sets will enhance the quality of data for: 1 Tracking public health conditions (complications, anatomical location) 2 Improved data for epidemiological research (severity of illness, co-morbidities) 3 Measuring outcomes and care provided to patients 4 Making clinical decisions 5 Identifying fraud and abuse 6 Designing payment systems/processing claims
There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM
Pregnancy trimester is designated for ICD-10-CM codes in the pregnancy, delivery and puerperium chapter.
A secondary user of ICD-9-CM codes is someone who uses already coded data from hospitals, health care providers, or health plans to conduct surveillance and/or research activities. Public health is largely a secondary user of coded data.
There are new concepts that did not exist in ICD-9-CM, such as under dosing, blood type, the Glasgow Coma Scale, and alcohol level.
The greater level of detail in the new code sets includes laterality, severity, and complexity of disease conditions, which will enable more precise identification and tracking of specific conditions.
The transition to ICD-10-CM/PCS code sets will take effect on October 1, 2015 and all users will transition to the new code sets on the same date.
These codes permit the classification of environmental events, circumstances, and conditions as the cause of injury and other adverse effects, and are to be used in addition to codes that report the actual injury.
The Y codes contain two important categories: Y92 for place of occurrence of the external cause and Y93, which is an activity code. The guidelines state these codes are to be used with one another, and are only reported on the initial encounter.
The Centers for Medicare & Medicaid Services (CMS) encourages you to do so, however, because they provide valuable data for injury research and evaluation of injury prevention strategies. They may also be helpful for determining liability in third-party injury claims.
ICD-9-CM has been the standard since 1979, but has outlived its usefulness. Because of its structure, ICD-10-CM provides better data for research and statistical analysis than ICD-9-CM. Although there is no national mandate to report them, external cause codes provide a unique opportunity to report significant detail not available in ICD-9-CM.
External cause code reporting is voluntary (but is encouraged) when ICD-10-CM is implemented. It provides the opportunity to report enhanced detail, and could streamline the process of claims submission and payment adjudication. It may also improve the process of data collection for researchers and policy makers. Physicians and coders, however, must take the time to get familiar with coding guidelines and conventions to take advantage of this opportunity provided by ICD-10 .#N#Sources:#N#Medicare Learning Network, ICN 902143, April 2013#N#Complete and Easy ICD-10-CM Coding for Chiropractic, 2nd edition, The ChiroCode Institute, 2013.#N#“ICD-10-CM.
