How coding accuracy improves sleep study billing services

 

Accurate coding serves as the foundation stone for revenue cycle management in sleep study billing. To diagnose conditions like obstructive sleep apnea or narcolepsy, sleep study implements the use of complex testing methods. Any errors in the billing process could lead to possible claim denials, delayed reimbursements, or compliance challenges.  

With the evolving coding guidelines and payer’s scrutiny of documentation processes, the claim denial rates for sleep studies have increased. This is where professional sleep study billing services have become invaluable in proper reimbursement techniques and adhering to insurance, regulatory, and coding guidelines.  

How CPT codes impact sleep study practices

The very basic necessity of accurate sleep study billing is the use of correct CPT codes. Sleep diagnosis is categorized into two different types: in-lab polysomnography and home sleep apnea tests. Each of these diagnoses has specific requirements under ICD-10, CPT, and HCPCS standards for coding.  

In-lab polysomnography refers to the detailed in-lab study that is conducted in a clinic by a qualified sleep study professional. The task of the sleep study professional includes sleep staging that requires EOG electrooculography and EMG electromyography. EEG electroencephalography is a medical examination that is conducted to record the electrical activities of the brain. EMG electromyography measures electrical activity of muscles and nerves. EMG electromyography helps in the evaluation of the health and functioning of the skeletal muscles. Below mentioned are the CPT codes required for the sleep study stages:

EOG electrooculography: CPT code 95808 for sleep staging that needs to be billed separately. It is used for patients who require additional sleep study procedures like CPAP titration for patients suffering from obstructive sleep apnea.  


EMG electromyography: CPT code 95869 for needle EMG in thoracic paraspinal muscles. The EMG needle refers to a diagnostic test for the muscles present along the spine of the human body, especially in the mid-back region.

Home sleep apnea testing (HSAT) involves the use of portable devices used by patients overnight. These tests are usually conducted to diagnose obstructive sleep apnea (OSA). The portable devices help in monitoring heart rate, blood oxygen levels, and airflow. The following codes are used in home sleep apnea tests:

CPT 95800: Used for unattended home sleep study (minimum parameters) which helps in measuring respiratory analysis and heart rate.

CPT 95801: Used for unattended home sleep study type III (comprehensive) which helps in measuring respiratory airflow and respiratory effort.

Insurance companies frequently demand documentation on the type of devices used in sleep study services. The proper documentation of each of these codes is important to reimburse claims, based on the type of sleep study service provided.

How correct coding benefits sleep study billing services

Coding in the healthcare industry requires attention to detail and knowledge of updated medical codes. Medical coding benefits sleep study services in the following ways:  

1. Establishing medical justification – Like every other medical service, sleep study also requires medical documentation to establish the medical necessity. This necessity enables the insurance companies to pay for the services provided by the sleep study specialists. The medical record of the patient needs to have extensive details of the patient’s conditions, referring physician’s recommendation, relevant clinical history, and supporting ICD-10 codes. Some of the frequently used ICD-10 codes include G47.10 for unspecified hypersomnia and G47.61 for periodic limb movement disorder. It is the responsibility of the billing services to match the diagnosis code with clinical documentation.
   
2. Assigning accurate codes and modifiers – Modifiers play a key role in clarifying how a particular sleep study service was provided. For sleep study billing professionals, it is important to understand the application of technical and professional components. If the same sleep study provider performs and evaluates the service, it is billed globally without any modifiers.
3. Claim submission with proper documentation – Submitting claims on time is a primary requirement for proper claim reimbursement. Timely claim submissions include the following necessary tasks:

• Interpretation report of the physician with authorized signature and all the essential details of the patient.
• Results of polysomnography tracings or HSAT devices that are retained according to the insurance company’s requirements.
• Summary of sleep scoring – This refers to the classified data collected during sleep tests.
• Prior authorization number – This number is recorded on the insurance claim and in the patient’s documentation. It plays an important role in reducing claim denials and speeding up the payment process.
