A Brief History of Medical Coding
Because the medical coding field is expanding so rapidly at the moment, it may seem like it’s a relatively new occupation… but this certainly isn’t the case!
Medical billing and coding have been around for decades. And just like fifty years ago, it continues to be an ever-changing field.
Believe it or not, the ICD-9 diagnosis coding system originated in 17th century England.
Statistical data was gathered through a system known as the London Bills of Mortality and arranged into numerical codes. These codes were used to measure the most frequent causes of death.
Fast-forward a few hundred years…
By 1937, this statistical analysis of the causes of death was organized into the International List of Causes of Death. Over the years, the World Health Organization (WHO) used this list more and more to assist in tracking mortality rates and international health trends.
The list was later developed into the International Classification of Diseases, which is now in its 10th edition, also known as the ICD-10-CM/PCS.
In 1977, the worldwide medical community recognized the ICD system, which then prompted the National Centers for Health Statistics (NCHS) to expand the study to include clinical information.
In other words, in 1977, the ICD system was expanded to not only include causes of death, but also clinical diagnoses such as illnesses and injuries.
Adding clinical diagnoses provided additional statistical information on basic healthcare. Now there was a way to index medical records, make medical reviews easier to complete, and provide further opportunities for medical care.
The ICD-10 version is much more specific than previous editions, for example, in ICD-9 there were only 13,000 codes and the “other” and “non-specified” codes were used for numerous diseases, conditions, and injuries. The ICD-10 has 68,000 codes, which eliminate a lot of the “other” and “non-specified” codes which help greatly with the reimbursement process.There will be a lot fewer denied claims and physicians and healthcare providers will be paid for specific services instead of generic cases.
There were numerous changes made between ICD-9 and ICD-10. Aside from the number of codes and the elimination of most of the “other” and the “non-specified” codes and the inclusion of combination codes for symptoms and diagnoses, fewer codes are needed to report and fully describe a patient’s condition. The code set has been expanded from five positions (first one alphanumeric, others numeric) to seven positions. The codes use alphanumeric characters in all positions, not just the first position as in ICD-9. When using a modifier, the codes expand to 6 or 7 positions.
So,why the Change from ICD-9 to ICD-10? The question on a lot of physicians, coders, and healthcare information specialists minds was why the change? Many of these people believed the change would only confuse everyone and make things worse; if it is not broken why fix it? What they didn’t realize is that the “system” was not only broken but dated and in need of upgrading. If hospitals, healthcare facilities, and private practice physicians were going to “stay in business” these changes were necessary and long overdue.
As medicine becomes more reliant on technology and web-based medical records, more changes are sure to take place involving medical billing and coding guidelines and the preservation and confidentiality of medical records. The Centers for Medicare and Medicaid Services and Centers for Disease Control and Prevention have already approved adding 3,651 ICD-10 hospital inpatient procedure codes and about 1,900 ICD-10 diagnosis codes for the fiscal year 2017. Implementation of the new codes will begin in October 2016.
Medical Coding is making history right now and the future of health care looks promising.

In the past, there had been an Excludes1 note at I46.- Cardiac arrest that excluded R57.0, Cardiac shock. HIA had also received a letter from AHA on a case in the past that had stated that only I46.- Cardiac arrest would be coded if both were documented. In addition, the Third Quarter Coding Clinic page 26 had a similar case that asked if both could be coded, and AHA had instructed that only I46.9, cardiac arrest, cause unspecified would be coded if both were documented and that the CDC would be looking at possible revision to the Excludes1 note.
A higher CMI corresponds to increased consumption of resources and increased cost of patient care, resulting in increased reimbursement to the facility from government and private payers, like CMS. We know that documentation directly impacts coding.
Lately we have seen several cases where the endarterectomy was assigned along with the coronary artery bypass (CABG) procedure when being performed on the same vessel to facilitate the CABG. A coronary artery endarterectomy is not always performed during a CABG procedure, so when it is performed it becomes confusing as to whether to code it separately or not.
Assign code Z20.828, “Contact with and (suspected) exposure to other viral communicable diseases” for all patients who are tested for COVID-19 and the results are negative, regardless of symptoms, no symptoms, exposure or not as we are in a pandemic.
The Centers for Medicare & Medicaid Services (CMS) announced new procedure codes for treatments of COVID-19 – effective as of August 1, 2020. Among the new codes are Section X New Technology codes for the introduction or infusion of therapeutics including Remdesivir, Sarilumab, Tocilizumab, transfusion of convalescent plasma, as well as introduction of any other or new therapeutic substances for the treatment of COVID-19.
One common element in many value-based programs is risk adjustment using Hierarchical Condition Categories (HCCs) to create a Risk Adjustment Factor (RAF) score. This method ranks diagnoses into categories that represent conditions with similar cost patterns.
Why are so many AKI records being denied? It’s hard to give one answer for why so many AKI records are being denied lately, but most appear to be due to the multiple sets of criteria available for use in determining if a patient has AKI, as well as physician documentation. As stated in Part 3 of this series, there are three main criteria/classifications used to diagnose AKI.
In previous parts of this series we looked at the definitions of AKI/ARF, causes, coding and sequencing, and the common clinical indicators that patients present with that are diagnosed with this condition. In Part 4, we will look at the documentation that should be present to report the diagnosis without fear of denial, as well as when a query is needed to clarify the diagnosis.
If the facility does a COVID-19 test, and test is negative, do I need a diagnosis code. The answer is yes, you will report a Z-code. The Z-code depends on the record documentation and circumstances of testing. For any patient receiving a COVID-19 test, if negative, there MUST e a Z-code to describe why the test was taken. (Test negative for COVID-19 and MD does not override negative results).
In the first parts of this series we looked at definitions of AKI/ARF, causes, coding and sequencing. In Part 3, we will look at what clinical indicators would possibly be present to support the diagnosis of AKI/ARF.
The FY2021 IPPS Proposed Rule is out and here are some highlights from it regarding ICD-10 Code proposals. We will know if these changes are permanent after the public comment period is over on July 10, 2020 and CMS prepares the Final Rule, usually out by August 1.
As discussed in Part 1 of this series, AKI/ARF is a common diagnosis that coders see daily. In Part 2, we are going to focus on the different types/specificity of AKI/ARF. We’ll learn what they mean, as well as how to code the diagnosis.
This is part 1 in a series focused on coding of acute kidney injury (AKI) and/or acute renal failure (ARF). AKI/ARF is reported often, but is also one of the most common diagnosis found in denials.
With the proliferation of COVID-19 cases, we thought we would put together a quick reference listing of some of the common scenarios that coders have asked about. As with all coding, coders should follow Official Guidelines for Coding and Reporting and the COVD-19 Frequently Asked Questions document by the AHA.
Effective March 1, Medicare will pay physicians for telehealth services at the same rate as in-person visits for all diagnoses, not just services related to COVID-19. This great for providers whose patients are reluctant to visit the office.
The biggest reasons why some hospital systems are moving to single path coding is to eliminate duplicative processes and to optimize productivity. In addition, costs are reduced when only one coder “touches” the record and completes both types of coding.
Effective with 4/1/2020 discharges, ICD-10-CM code U07.0 is used to report vaping -related disorders. ICD-10-CM code U07.0 (vaping related disorder) should be used when documentation supports that the patient has a lung-related disorder from vaping. This code is found in the new ICD-10-CM Chapter 22. U07.0 will be in listed in the ICD-10-CM manual under a new section: Provisional assignment of new disease of uncertain etiology or emergency use.
The US government and public-health officials are urging consumers to utilize telemedicine for remote treatment, fill prescriptions and get medical attention during the new coronavirus pandemic. The goal is to keep people with symptoms at home and to practice social distancing if their condition doesn’t warrant more intensive hospital care.
Coronavirus: Tips for working from home. Companies around the world have told their employees to stay home and work remotely. Whether you’re a new to this concept or a work from home veteran, here’s some tips to staying productive from our #HIAfamily.
This is the final part of a three part series in which we address how coders can better interact with Clinical Documentation Improvement (CDI) professionals. In this part, we provide an actual example of an effective communication response to CDI.
This is part two of a three part series in which we address how coders can better interact with Clinical Documentation Improvement (CDI) professionals. In this part, we discuss mismatches and how to best go about resolving them. In part three we will provide a case example of best practice interaction.
This is part one of a three part series in which we address how coders can better interact with Clinical Documentation Integrity (CDI) professionals. Many times these departments are separate and the remote environment makes it difficult to interact efficiently between the two departments. In part one, we will discuss the history and objectives of CDI so the coder has a better understanding of CDI’s role.
One reason that coders should report chronic conditions (including history and status codes) on outpatient records is the HCC’s—Hierarchical Condition Categories. The quick and easy explanation of what HCC’s are is each HCC is mapped to certain ICD-10-CM codes or code ranges. HCC coding is designed to estimate future health care costs for patients.
For Part 4 of this 5-part series, we will look at Chapter 10 within ICD-10-CM—J00-J99—Diseases of the Respiratory System. There is no possible way to include every guideline or coding reference for this chapter, but here are some of the most common issues.
For Part 3 of this 5 part series, we will look at Chapter 9 within ICD-10-CM—I00-I99—Diseases of the Circulatory System. This chapter contains so many of the everyday diagnoses that we code such as hypertension, heart disease and stroke.
For Part 2 of this 5-part series, we will look at Chapter 1 within ICD-10-CM—A00-B99—Certain Infectious and Parasitic Diseases. There is no possible way to include every guideline or coding reference for this chapter, but here are some of the most common issues.
For Part 1 of this 5-part series, we will look at Chapter 21 within ICD-10-CM—Z00-Z99—Factors influencing health status and contact with health services. There is no possible way to include every guideline or coding reference for this chapter, but I’ll do my best to touch on some off the most common issues.
The HIM world has been buzzing recently with discussion of “Social Determinants of Health” and coded data. What does this mean for coders and the HIM field?
In response to the recent occurrences of vaping related disorders and in consultation with the World Health Organization (WHO) Framework Convention on Tobacco Control, the WHO Family of International Classifications (WHOFIC) Network Classification and Statistics Advisory Committee (CSAC) was convened to discuss a diagnosis code for vaping related illness for immediate use.
