MEDICAL CODING PROCESS

Author: Vamsi Krishna

Medical Coding

Medical coding is the process of converting diagnoses, treatments, services, and equipment used in healthcare into standard medical alphanumeric codes. The diagnoses and procedure codes are derived from the documentation in the medical records, such as the transcription of the doctor’s notes, the results of the laboratory and radiologic tests, etc. experts in medical coding assist in ensuring a proper application of the codes is made during the medical billing process. which entails Taking the relevant data from the associated documents, allocating the proper codes, and generating a claim that will be reimbursed by insurance companies.

whenever you see a medical practitioner, medical coding takes place. The healthcare provider examines your problem and medical history, identifies the issue, decides how to treat you, and logs your visit. That paperwork not only forms the foundation for the patient’s continued record, but it also forms the basis for the healthcare provider’s reimbursement.

Need for Medical Coding

It is necessary to document a patient’s diagnosis, test findings, and therapy in order to ensure future visits will be of the highest caliber and to be reimbursed. The patient’s personal health records must be simple to understand and follow them throughout any subsequent complaints and treatments. Given the hundreds of millions of visits, operations, and hospitalizations that occur each year in the United States, this is particularly significant.

There are countless problems, illnesses, accidents, and fatalities. A comparable number of injectable medications and supplies, along with the thousands of services that providers do, need to be monitored. These are categorized by medical coding for simpler reporting and tracking. Each disease, process, and tool has a number of different names, eponyms, acronyms, and descriptions in the healthcare industry. All of these components are presented and spoken in a uniform manner thanks to medical coding, making it simpler to understand, monitor, and do changes to them.

Thanks to technology, communication between hospitals, providers, and payers is swift and reliable to the Health Information Portability and Accountability Act (HIPAA), which mandates the use of a standard language. The majority of confidential health information is stored digitally and is based on the allocated codes.

Types of Codes Used

Worldwide, medical coding is done, with the International Classification of Diseases being used in the majority of nations (ICD). The World Health Organization maintains the ICD, and each member nation modifies it to suit its own needs. There are six official HIPAA-mandated code sets in the US that are used for various purposes. Systems for categorizing medical codes are collections of codes that relate to certain treatments and diagnoses. They aid in the procedure for billing for medical services and are used to precisely monitor information about illnesses and medical problems in patient records. Hospitals and care facilities aren’t the only places that employ medical coding classification systems. They are also used by private insurers and government health programs for a range of functions, such as tracking outbreaks, using decision support systems, and statistical analysis of diseases and treatments.

There are various categories that are utilized for particular purposes under the overall categorization system for medical coding. For instance, healthcare professionals describe diseases and their symptoms using diagnostic codes, whereas they use procedural codes to denote surgical or medical operations. Understanding the classification of a medical coding system might help you better comprehend its function and goal. The classification schemes that are employed in the field of We briefly discuss medical billing and coding described in the list that follows.

1. ICD-10-CM (International Classification of Diseases, 10th Edition, Clinically Modified)

ICD-10-CM contains codes for everything that can harm, ill, or kill you. The 69,000-code database includes codes for diseases, toxins, neoplasms, wounds, their causes, and the things people were doing when the wounds remained intact. Codes are “smart codes” can have up to seven alphanumeric characters and express the patient’s complaint in detail. For recording and proving medical necessity for services, ICD-10-CM is employed. It also serves as the framework for the MS-DRG system described below.

2. CPT® (Current Procedure Terminology)

More than 8,000 alphanumeric codes with five characters that describe the services rendered to patients by doctors, other healthcare professionals, therapists, and others are included in this code set, It is a property of the American Medical Association and is kept up to date. The CPT® system is employed to report the majority of outpatient services. It is also used by doctors to document the services they provide to inpatients.

3. ICD-10-PCS (International Classification of Diseases, 10th Edition, Procedural Coding System)

To describe surgical procedures performed in operating rooms, emergency departments, and other settings, hospitals use the 130,000-character ICD-10-PCS code set. By properly utilizing ICD-10-PCS coding, you can avoid being intimidated by the procedural coding.

4. Level II HCPCS (Health Care Procedural Coding System)

HCPCS Level II’s more than 7,000 alphanumeric codes are used for many more things, including quality measure tracking, outpatient surgery billing, and academic studies. They were initially created to be used by Blue Cross/Blue Shield, Medicare, Medicaid, and other providers to report procedures and charge for supplies.

5. CDT® (Code on Dental Procedures and Nomenclature)

The American Dental Association is the owner and maintainer of CDT® codes (ADA). The HCPCS Level II dental section was previously represented by the five-character codes that begin with the letter D. The majority of dental and oral procedures use CDT® codes for billing.

6. NDC (National Drug Codes)

Each and every packet of medication is tracked and claimed employing the Federal Drug Administration’s (FDA) code set. Pharmaceuticals that have been prescribed, sold, and used can be identified by providers, suppliers, and federal organizations. The 10 –13 alphanumeric smart codes are appreciated.

7. Modifiers

Hundreds of alphanumeric two-character modifier codes are used in CPT® and HCPCS Level II codes to increase clarity. They may denote a patient’s status, the area of the body where the service is being provided, a payment instruction, an occasion that changed the service to which the code refers, or a quality element.

8. MS-DRG and APC

MS-DRG and APCs are two sets of federal codes that are utilized to support payments derived from the aforementioned systems. They draw on already-existing code sets but also provide information on the resources needed by the facility to deliver the service.

9. MS-DRG (Medical Severity Diagnosis Related Groups)

A hospital submits MS-DRGs in order to get paid for a patient’s stay. The ICD-10-CM and ICD-10-PCS reported codes form the basis of the MS-DRG. A specific set of aspects of the patient, such as the primary diagnosis, particular secondary diagnoses, procedures, sex, and discharge status, describe them. This data set is maintained by the Centers for Medicare & Medicaid Services (CMS) in collaboration with 3M HIS.

10. APC (Ambulatory Payment Categories)

The Hospital Outpatient Prospective Payment System (HOPPPS) is provided by the Centers for Medicare & Medicaid Services (CMS), which maintains APCs (OPPS). This system covers some of the hospital’s outpatient services, including minor surgery and other treatments.

11. CODES FOR PROFESSIONALS AND FACILITIES

Medical coders also convert the medical record into codes for businesses and facilities when necessary. Professional codes record delivered clinical services from doctors and other healthcare providers and link those services to a code for invoicing. These codes come from the data kept in a patient’s medical record. Hospitals, on the other hand, employ facility codes to track the expenses and overhead associated with providing medical care. These codes record the costs associated with nursing staff, technical care components, medical equipment, supplies, and medications. When a provider who works for the hospital provides clinical services, the hospital is permitted to put professional codes on claims. However, the facility cannot have a professional code if a non-hospital practitioner uses the hospital’s resources and space.

 Process of Medical Coding

• Medical coders with training and certification tend to be the best. Below is an example of a normal day in a medical coder’s life. Once a Medical Coder has settled onto their workstation, they frequently begin each day by reviewing the batch of patient notes from the previous day for analysis and coding.
• Depending on the therapeutic environment (outpatient or facility), It may be necessary depending on the records and notes. an exact degree of specialty (Healthcare systems may employ people who concentrate on certain medical specializations, whereas coders employed by smaller, more general offices might deal with a wider range of patients and medical issues.)
• To begin, the coder selects the top patient note or billing sheet in the stack and starts reviewing the documentation to understand the diagnoses provided to the patient and the procedures performed. out during their visit.
• The coders also take vital information from the documentation, such as the names of the doctors, the dates of the operations, and other pertinent information. Coders begin by using the ICD-10 and CPT® code books to translate the doctor’s notes into useful medical codes.
• Below is an illustration of basic procedure documentation with the corresponding codes. Medical coders individually gain in-depth knowledge of the procedures and patterns employed in their own clinic or institution.
• Coders may come across difficult notes that call for in-depth research and extra effort to code correctly. Even among the more regularly used codes, there are significant grey areas that coders may analyse.
• Coding standards can be difficult to understand in circumstances that are extremely complex or uncommon.
• In order to discuss specifics in online forums, network with experts they met at national conferences, or get assistance from coworkers, seasoned coders will rely on their network of peers and industry experts. comprehend the problem and choose the appropriate codes.
• Continuous Knowledge and professionalism can be significantly improved through education and reading current coding-related magazines, such as Healthcare Business Monthly.
• The Finally, the coder completes the patient record and begins the next chart. Reading each chart, making notes, assigning codes, and entering data into a computer are all steps that must be completed repeatedly.
• The majority of a coders will be spent today at a computer reading notes, data entry into a billing system, or looking up material to clarify the documentation in the notes.

Procedures for Coding and Delivery

A coder receives a batch of hospital intake forms or charge sheets, abstracts the handwritten information on them, converts it to code, and sends them to data entry. Our programmers have a minimum of 4 years of practical experience and are AAPC (American Academy of Professional Coders) certified. They perform the coding for the charge sheet’s handwritten diagnoses.

1. Pre-Sales Requirements Analysis – Specialties covered, turnaround time needed, file type, report format requirements, and client needs analysis are all included.
2. Receipt of Files from client – Through an FTP server, we receive scanned clinical data or patient charts from the client.
3. Download and Allocation of Files – Our medical coding team downloads these files and distributes them to the proper pre-coders and coders.
4. Pre-Coding – The Pre-Coders insert information such as the location of the service, the name of the treating physician, and any price modifiers after the files have been downloaded and assigned to the relevant team.
5. Coding- Using resources including ICD-10-CM, LMRP, CPT Assistant, and HCPCS Level II, Certified Coders (CPC) do procedural and diagnostic coding.
6. Uploading of Completed Files – The coding team also examines if the diagnosis and the operation code are compatible. When coding is successfully finished, the files are uploaded to our FTP server.
7. Quality Evaluation – The client receives the coded files from our FTP server. The client evaluates the quality of these files.
8. Client Feedback – We aim to improve and refine the process in response to client input in order to deliver the most precise and trustworthy services.

standardized medical coding dictionaries in the market

Although there are several standardized medical coding dictionaries available, only the five listed below are utilised for coding:

1. COSTART – Coding Symbols for Thesaurus of Adverse Reaction Terms

2. ICD9CM – International Classification of Diseases 9 Revision Clinical Modification

3. MedDRA – Medical Dictionary for Regulatory Activities

4. WHO-ART – World Health Organisation Adverse Reactions Terminology

5. WHO-DDE – World Health Organisation Drug Dictionary Enhanced

MedDRA and WHO-DDE are two popular medical coding dictionaries that are used to code medical terminology produced in clinical trials out of the five mentioned above. It is nearly impossible to maintain consistency in reporting a term in any given clinical trial. But it can be difficult for a coder to make sure being the term “reported on data collecting instrument” (CRF/eCRF) is coded correctly. It is common knowledge that these dictionaries are expensive and that companies performing medical coding activities need to hold the necessary, active licenses. For each of the dictionaries, certain licenses are given to specific user groups-z.

An Overview of Medical Coding

MEDICAL CARE

Why is working in medical coding a great choice? It enables you to contribute to the field of healthcare without needing years of education. Given that it has a direct bearing on…, medical coding is essential for patient care.

• demographic evaluations
• treatment results
• research into diseases
• It thoroughly examines patient information, diagnoses, drugs, techniques, and treatments; it then converts all of this data into alphanumeric codes. Where was this data obtained? Well, the patient information is gathered from numerous sources, such as…
• lab findings
• digital records
• clinical records
• Transcriptions
• Urinalysis
• radiologic evaluations
• pathology evaluations

The intention is to guarantee both smooth reimbursement and top-notch medical care during subsequent visits.

USE & DOCUMENTATION OF CODING

• The ICD-10 standard alone has nearly 70,000 codes that are used in various healthcare procedures. In addition, there are the Current Procedural Terminology (CPT) codes and the Healthcare Common Procedure Coding System (HCPCS) Level 2 codes.
• ICD codes give descriptions of disease, harm, or demise. Surgery, imaging, measurement techniques, anaesthesia, etc. are all covered by CPT codes. HCPCS codes highlight medical assistance and outpatient hospital care.
• Medical professionals record the therapy, diagnosis, or other services that a patient receives in a patient’s record. Then, the products are given the appropriate codes by the coders so that the insurance companies may get precise claims.
