The Step-by-Step Medical Billing Process
The medical billing process follows a logical sequence of steps, each building upon the previous one. Understanding this sequence helps billing specialists see how their work fits into the larger picture of healthcare administration and revenue cycle management.
Step 1
Patient sees the physician, who evaluates the patient’s condition and provides treatment. The provider documents their findings, diagnoses, and all procedures performed. This documentation must be thorough and specific enough to support the codes that will be assigned.
Step 2
The clinical documentation is translated into standardized codes. ICD-10 codes describe the patient’s diagnoses, while CPT codes describe the procedures and services performed. These codes are recorded on a superbill or charge ticket, which serves as the source document for claim creation.
Step 3
The billing specialist enters superbill information along with patient demographics and insurance details into the practice management software. This creates an electronic claim that can be transmitted to the insurance company. Before transmission, the claim should be reviewed for accuracy and completeness.
Step 4
If the claim encounters problems—such as rejection by the clearinghouse or denial by the payer—the billing specialist must investigate the cause, correct any errors, and resubmit the claim. This may involve contacting the insurance company, obtaining additional documentation, or filing an appeal.
Step 5
When payment is received, it comes with a remittance advice that explains how the payment was calculated. The billing specialist posts this payment to the patient’s account and makes any necessary adjustments. If there’s a patient responsibility amount, a statement is generated and sent to the patient.
Step 6
Unpaid claims and patient balances require ongoing follow-up. The billing specialist monitors accounts receivable aging reports, follows up on outstanding claims, and may need to work with patients on payment arrangements or transfer seriously delinquent accounts to collections.
Medical billing and coding are two closely related aspects of the modern health care industry. Both practices are involved in the immensely important reimbursement cycle, which ensures that health care providers are paid for the services they perform. For the sake of simplicity, let’s divide the two at the moment and look at them as separate pieces of a larger process. We’ll begin with medical coding.
MEDICAL CODING
Medical coding, at its most basic, is a little like translation. It’s the coder’s job to take something that’s written one way (a doctor’s diagnosis, for example, or a prescription for a certain medication) and translate it as accurately as possible into a numeric or alphanumeric code. For every injury, diagnosis, and medical procedure, there is a corresponding code. There are thousands and thousands of codes for medical procedures, outpatient procedures, and diagnoses.
Let’s start with a quick example of medical coding in action. A patient walks into a doctor’s office with a hacking cough, high production of mucus or sputum, and a fever. A nurse asks the patient their symptoms and performs some initial tests, and then the doctor examines the patient and diagnoses bronchitis. The doctor then prescribes medication to the patient. Every part of this visit is recorded by the doctor or someone in the healthcare provider’s office. It’s the medical coder’s job to translate every bit of relevant information in that patient’s visit into numeric and alphanumeric codes, which can then be used in the billing process.
There are a number of sets and subsets of code that a medical coder must be familiar with, but for this example we’ll focus on two:
- The International Classification of Diseases, or ICD, codes, which correspond to a patient’s injury or sickness, and
- Current Procedure Terminology, or CPT, codes, which relate to what functions and services the healthcare provider performed on or for the patient.
These codes act as the universal language between doctors, hospitals, insurance companies, insurance clearinghouses, government agencies, and other health-specific organizations. The coder reads the healthcare provider’s report of the patient’s visit and then translates each bit of information into a code. There’s a specific code for what kind of visit this is, the symptoms that patient is showing, what tests the doctor does, and what the doctor diagnoses the patient with.
Every code set has its own set of guidelines and rules. Certain codes, like ones that signify a pre-existing condition, need to be placed in a very particular order. Coding accurately and within the specific guidelines for each code will affect the status of a claim. The coding process ends when the medical coder enters the appropriate codes into a form or software program. Once the report is coded, it’s passed on to the medical biller.
