Medical coding and health information management can be an extremely rewarding and lucrative field, which makes the value of a coding education, priceless.
CPT 2020 revisions took effect on January 1, 2020. In Part 2 of our series on these changes, we continue with a discussion of revisions in the Evaluation and Management, and Medicine sections, along with an overview of updates in the Radiology, Pathology and Laboratory, and the new Category III codes.
At first glance, physicians and nurses would seem to be the ones running the show at medical facilities nationwide. That is a reasonable observation, as they are the people who treat patients. However, there are numerous other individuals working at hospitals, medical facilities and other healthcare settings doing work that makes visits with doctors possible. Two such examples of this work are the processes of medical coding and billing.
What is Medical Billing?
A vital process in the uninterrupted functioning of any hospital or medical facility is medical billing. Medical billing encompasses preparing billing claims and submitting them to insurance providers. This safeguards that the medical office or hospital is reimbursed the correct amount for the services that they deliver to patients.
Medical offices receive funding from private insurances providers and various healthcare programs, which are offered by the government. Receiving proper funds enables the medical office to stay in business. With suboptimal reimbursement, it is problematic for these facilities to deliver stellar healthcare to patients.
|The need for keeping everything in a short and systematic way has birthed the concept of medical coding services. This process refers to changing-over the healthcare diagnosis, medical services and equipment into a combination of alphanumeric medical codes. This conversion guarantees uniform documentation and helps administrations identify the effectiveness and prevalence of the treatment.|
What is Medical Coding?
While it also pertains to the all-imperative aspect of insurance reimbursement, medical coding varies in that it involves an exclusive code for each diagnosis, procedure, and prescription. The translation of diagnoses, prescription, and procedures into these universal codes enables the health care provider to process the bill accurately.
ICD-10, The International Classification of Disease, is the existing book of codes reinforced across the vast world of healthcare. Produced by the World Health Organization (WHO), the ICD-10 and its components are important not only for maintaining billing and records, but also for enabling data on diseases to be kept both nationally and worldwide.
Why We Code?
Let’s begin with a simple question about medical coding: Why should we code medical reports? Wouldn’t it be adequate to list the symptoms, diagnoses, and procedures, send them to an insurance company, and wait to hear which services qualify for reimbursement?
According to the Centers for Disease Control (CDC), there were approximately 1.4 billion patient visits in the previous year. That’s a stat that comprises visits to hospital outpatient facilities, physician offices, and emergency departments. If we estimate only five pieces of coded information per visit, which is an exceptionally low estimate, that’d be 6 billion discrete pieces of information that are supposed to be transferred every year. In a system flooded with data, medical coding enables for the efficient transfer of huge silos of information.
Coding also enables for uniform documentation between medical facilities. The code for streptococcal sore throat is identical in Hawaii as it is in Arkansas. Having uniform data enables efficient analysis and research, which government and health agencies use to track health trends much more competently. If the CDC, for instance, wants to analyze the prevalence of viral pneumonia, they can search for the number of recent pneumonia diagnoses by searching for the ICD-10-CM code.
In conclusion, medical coding companies enable administrations to look at the incidence and effectiveness of treatment in their facility. This is particularly important to large medical facilities like tertiary-care hospitals. Like government agencies tracking, for instance, the incidence of a certain disease, medical facilities can track the efficiency of their practice by analyzing
Now that we’ve covered the importance of medical coding services companies, let’s take a look at the three types of code
A Brief Account of 3 Types of Coding:
“ICD-10” stands for International Classification of Diseases, Tenth Edition. ICD-10 codes are created by the World Health Organization and accepted by governments all over the world.
Stands for “Current Procedural Terminology,” codes are updated yearly and are divided into three categories:
Category 1: Five-digit codes with descriptions that correspond to a procedure or service.
Category 2: Alphanumeric tracking codes employed for execution measurement.
Category 3: Provisional codes for new and emerging procedures, technology, as well as services.
HCPCS Level II
HCPCS stands for “Healthcare Common Procedural Coding System” and is based on CPT. HCPCS Level II codes are typically used for products and supplies that are not directly related to a physician, for instance, drugs, ambulance services, etc.
How Medical Coding Streamlines Hospital’s Finances
To this point, it is precisely clear that medical coding and billing are imperative processes to the upkeep of hospitals and medical facilities. Medical offices rely heavily on insurance providers and other healthcare initiatives for funding.
Insurance businesses make their profit by charging those who bear policies monthly fees, or premiums. The buy-ins from the people in the pool allow the insurance providers to cover the bulk of medical costs of policyholders, based on the policy. Bearing that in mind, that is a lot of money coming in from reimbursements and not out of the clients’ pockets.
That is why it is extremely important for medical billing and coding to be completed (and completed accurately). For every patient visiting a hospital, immediate care center or other medical facility has information that needs to be documented.
Not only that, but accurate medical billing and coding are important in making sure that patients aren’t left paying more for a procedure than they should, and that they and their insurance are charged for the correct services.
On April, we provided an overview of the upcoming ICD Code Revisions for FY2020. In July, we covered in detail the 2020 Proposed Rule for the Inpatient Prospective Payment System (IPPS) CMS-1716-P, which was published in the Federal Register, May 3, 2019.
This years’ updates to the ICD-10-PCS Official Guidelines for Coding and Reporting include a new section, updates to an existing section, new guidance on a body part, some editorial changes and the introduction to the possibility of exceptions for special cases. In addition, the Guideline changes also included exceptions regarding mastectomy procedures, followed by immediate reconstruction; a welcomed change.
The Exceptions: Mastectomies Coded in All Circumstances- Immediate Replacement Included
The Introduction includes this new line regarding the guidelines: “They are intended to provide direction that is applicable in most circumstances. However, there may be circumstances where exceptions are applied.”
- A dilemma solved for coding professionals. The exceptions that were included in the updated guidelines involve a mastectomy followed by immediate reconstruction. It was a matter or timing that determined whether the mastectomy was coded. If a patient had a mastectomy during the current encounter and a subsequent reconstruction at a different episode, then the mastectomy was coded for the first encounter, and the reconstruction for the next one. This was different in the case of a mastectomy followed by immediate reconstruction during the same encounter. Before 2020, following the guidelines meant that in the case of immediate replacement, the mastectomy would not be coded as it was necessary to remove the native breast first before replacing it. The exceptions to the guidelines give coding professionals a solution to this dilemma. They also bring the guidelines in line with the advice published in the Third Quarter 2018 Coding Clinic page 13, in the article: Deep Inferior Epigastric Artery Perforator Flap Breast Reconstruction: mastectomy is coded separately, and the harvest of the DIEP graft is not reflected in a separate code.
- Guideline B3.1b has been updated to state that Components of a procedure specified in the root operations definition or explanation as integral to that root operation are not coded separately. The exception is listed: Exceptions: Mastectomy followed by breast reconstruction, both resection and replacement of the breast are coded separately. This contrasts the resection of the native breast before replacement to the example given in the guideline: Resection of a joint as part of a joint replacement procedure is included in the root operation definition of Replacement and is not coded separately. As noted in the Third Quarter 2018 Coding Clinic article, “Mastectomy with breast replacement/reconstruction and joint replacement surgery are conceptually very different. In joint replacement, the objective is to restore function by replacing the joint. For a mastectomy with reconstruction, it is important to identify that the primary objective of the surgery is to remove cancerous or potentially cancerous breast tissue, and that the reconstruction is an additional objective.”
- The changes in guideline B3.9 also relate to these circumstances. 9 instructs that if an autograft is obtained from a different procedure site in order to complete the objective of the procedure, a separate procedure is coded. Excision of a saphenous vein for a coronary bypass is highlighted as an example.
- The updated guideline lists the exception to this guideline: Except when the seventh character qualifier value in the ICD-10-PCS table fully specifies the site from which the autograft was obtained.
- Added to the saphenous vein example is the following: Replacement of breast with autologous deep inferior epigastric artery perforator (DIEP) flap, excision of the DIEP flap is not coded separately. The seventh character qualifier value Deep Inferior Epigastric Artery Perforator Flap in the Replacement table fully specifies the site of the autograft harvest. This updated guideline and example are telling us that including a code for the harvest would not add any information as the source of the graft is listed in the 7th character qualifier, and therefore the additional code is not required.
Edits in the Guidelines
While there is no change in guideline A9 that instructs that within a PCS table, valid codes include all combinations of choices in characters 4 through 7 contained in the same row of the table; the code table used as an example has been updated to include device value Y “other device” that has been added to the 0JH code table.
- Guideline B2.1a for body systems had some editorial changes, listing the complete titles of the Anatomical Regions body systems and removing the Control example, since this root operation can now be coded in in other body systems. Also added was an example: Amputation of the foot is coded to the root operation Detachment in the body system Anatomical Regions, Lower Extremities.
- The root operation Extraction was added to B3.5 for overlapping body layers, stating that for root operations such as Excision, Extraction, Repair or Inspection performed on overlapping layers of the musculoskeletal system, the body part specifying the deepest layer is coded.
- In guideline B4.1b for body part that addresses the prefix “peri,” guidance is given for the periosteum: A procedure site documented as involving the periosteum is coded to the corresponding bone body part.
A New Section of Guidelines, and Updates to New Technology
A completely new section with two guidelines, section D, is added for Radiation Therapy. The new guidelines concern Brachytherapy and instruct when separate codes are needed from the Medical and Surgical section for Insertion of the brachytherapy source that remains in the body at the end of the procedure. Also covered is the placement of a temporary applicator for brachytherapy delivery. Review these guidelines carefully.
- With the addition of the Radiation Therapy section, the New Technology guidelines from section X have been moved to E, with some edits and the addition of a new guideline. The updated guidelines specify when a New Technology code may be the only code reported and when they may be additional codes reported along with codes from other sections of ICD-10-PCS. One example given is for the use of dual filter cerebral embolic filtration, coded as X2A5312 used in conjunction with a transcatheter aortic valve replacement (TAVR); both codes are assigned.
While the updates to the 2020 guidelines are not extensive, there are important changes that warrant careful review. You can find the full document here: https://www.cms.gov/Medicare/Coding/ICD10/Downloads/2020-ICD-10-PCS-Guidelines.pdf

As a follow-up to our previous article “The HCC Coding Specialist: Benefiting payers, providers, and patients” we now delve in deeper to the background and overview of HCC risk adjustment for the Medicare Advantage Program.
Background on Payment in the Medicare Advantage Program
The Medicare Advantage (MA) program allows Medicare beneficiaries to receive Part A and Part B benefits from private insurers, otherwise known as Medicare Advantage Organizations (MAOs) that contract with the Centers for Medicare and Medicaid Services (CMS) to provide benefits as an alternative to the traditional Fee-for-Service (FFS) Medicare program. There has been a steady increase in Medicare Advantage enrollment as a proportion of total Medicare enrollment. In 2003, only approximately 13% of the Medicare population was enrolled in a Medicare Advantage (MA) plan. In 2014, Medicare Advantage (MA) enrollees accounted for 30% of all Medicare beneficiaries. And in 2018, MA enrollees grew to 36% of all Medicare beneficiaries (source: cms.gov).
CMS pays each Medicare Advantage Organization (MAO) a monthly per-person amount for each beneficiary enrolled in its plan. The plan payment rates are determined by the plan’s bid, which is submitted to CMS on an annual basis. The per-person amount paid to each plan for enrolled beneficiaries is adjusted to account for differences in health status between enrolled beneficiaries. This is referred to as “risk adjustment” model, and was authorized by the Balanced Budget Act of 1997 (BBA). From 1997 to present, there have been several different types of risk adjustment models. But, in 2004, CMS selected a new risk adjustment model to begin using for payment: Centers for Medicare & Medicaid Services (CMS) Hierarchical Condition Categories (CMS-HCC) model, which includes diagnoses recorded on professional, inpatient, and outpatient claims.
CMS-HCC Model overview
The CMS-HCC model is prospective where data is collected in the base year to determine expected costs for the following year (the “prediction” year). For example, data from 2019 (base year) will be used to predict expenses in 2020 (prediction year). Each segment of the CMS-HCC model relies on data from demographics (i.e. patient’s age and gender) and health status, based on ICD-10-CM diagnosis codes, to predict costs. To identify the disease diagnoses that predict future healthcare costs, HCC models first organize diseases/conditions into body systems or disease processes, called diagnostic groups (DXGs). The disease processes within each diagnostic group (DXG) are further organized into condition categories (CCs) and then delineated into the HCC. ICD-10-CM diagnosis codes are ranked into categories that represent conditions with similar cost patterns. There are over 9,500 ICD-10-CM codes that map to one or more of the 83 HCC codes included in the 2019 CMS-HCC Risk Adjustment Model (Version 23).
Here’s an example of HCC categorization:
NOTE: HCC 88 Angina Pectoris is a payment HCC. However, it is excluded from the clinical vignette for this patient since HCC 88 is in the same hierarchy as HCC 86, which is more severe (more at: https://www.cms.gov/)
The CMS-HCC model focuses on long-term chronic conditions such as diabetes, autoimmune disorders, end stage liver disease, end stage renal disease, chronic obstructive pulmonary disease (COPD), and congestive heart failure (CHF) that impact the probability of future healthcare costs. The CMS-HCC model does not include acute illnesses and injuries that are not reliably predictive of ongoing healthcare costs.
Coding professionals need to review the entire medical record documentation to assign appropriate ICD-10-CM diagnosis codes. Most chronic conditions are assigned to an HCC. HCC categories report all conditions that affect the patient’s health status concurrently across the continuum of care. To support an HCC, medical record must support the presence of the disease/condition and also include the clinical provider’s assessment and/or plan for management of the disease/condition. Most organizations use the “M.E.A.T” criteria: Monitoring, Evaluation, Assessment, Treatment for their documentation practices as well as ICD-10-CM diagnosis coding and HCC assignments.
This article successfully covered how the complexity of documentation, coding, and the patient’s ICD10-CM diagnosis codes can have an important impact on HCCs. Accurate diagnosis coding is essential for appropriate risk adjustment which drives the most suitable reimbursement for physician services. Be sure that your clinical providers and coders are educated about HCC documentation and coding! Additional articles will be presented on the YES blog.
