CPT Code 62323: Description & Reimbursement Guidelines

628.8 million! That is how many people suffer from lower back pain, according to the National Institutes of Health. This shows how common lower back pain really is. However, in most cases, people try to manage this pain with painkillers.

But what happens in more serious cases that require detailed diagnosis and treatment? Well, medical billing professionals resort to specialized methods. One such method falls under CPT code 62323. 

Before we get to the technical details and guidelines of the CPT code, let’s discuss it a little.

CPT Code 62323 – Description

Back problems are very common in several professions, especially white-collar jobs. Such professions require individuals to sit for long hours, inflicting excessive load on the spine, leading to pain. However, most people prefer relying on painkillers for pain management. 

Unfortunately, in some cases, the pain does not subside with painkillers and requires further intervention. For instance, an epidural or subarachnoid injection may be administered to manage the condition. In such cases, the injection is administered into the lower spine using a needle or catheter.

The main purpose is to introduce a diagnostic or therapeutic substance, commonly called a steroid or a pain reliever. This procedure is performed on the lumbar (lower back) or sacral (tailbone) regions of the spine. 

This process is billed under CPT code 62323 and includes fluoroscopic imaging. 

Cases Where CPT Code 62323 Applies

Physicians may use CPT code 62323 in several scenarios. Let’s discuss a few before moving forward.

Back Pain from Minor Vehicle Accident

Suppose a 19-year-old male visits a physician’s clinic to report persistent lower back pain. The physician gathers patient history and finds the individual had been in a minor car accident a few months back and showed no initial symptoms. 

However, the patient started experiencing pain in his lower back shortly after, and tried managing it with over-the-counter painkillers, instead of opting for physical therapy or professional medical treatment. Unfortunately, that approach did not provide long-term relief. 

The physician orders an MRI, which later indicates inflammation in the L4-L5 and L5-S1 spinal segments. He uses fluoroscopic imaging guidance for the insertion of a lumbar epidural steroid injection. Once the correct space is identified, a combination of local anaesthetic and corticosteroid (e.g., dexamethasone) is injected. 

The service is finally billed under the CPT code 62323.

Excessive Leg Pain

Consider a 55-year-old woman experiencing extreme pain in the legs because of sciatica. When visiting the physician, she further explains that the pain has worsened over the last few days and is currently unbearable. This has hindered her daily activities, impacting her quality of life. 

The physician checks the patient’s medical history and latest MRI reports, which provide further details. It explains the pain runs down her leg, and neither physiotherapy nor oral medicines helped with pain relief. Thus, the physician suspects sciatica-induced nerve inflammation in multiple interspaces (e.g., L3-L5).

Finally, the medical expert uses CT imaging to place the needle into the interlaminar epidural space and administers the injection to counter the pain. 

Therefore, the billing team uses CPT code 62323 for reimbursement.

Modifiers to Append with CPT Code 62323

The following are the best-suited modifiers used with CPT code 62323:

Modifier 59

If a separate procedure is performed on the same day, then modifier 59 should be used. For instance, if a physician performs two distinct procedures on the same patient on the same service date, this modifier applies.

Note: We recommend reviewing the payers’ guidelines and compliance before choosing this modifier. 

Modifier KX

Medical necessity of pain management injections is imperative where physical therapy has been insufficient. The modifier KX declares that the service meets the coverage criteria and qualifies for reimbursement. 

It can be considered a green light to carry out a particular service based on medical necessity, even after the thresholds have been met or exceeded. The modifier may then be used with CPT code 62323 to avoid frequency-related denials.

Reimbursement Guidelines for CPT Code 62323 

The following are the CPT code 62323 guidelines that billing professionals should be mindful of:

Provide All Necessary Documentation

Complete documentation is integral to any medical claim, and incomplete or wrong documents can lead to denials. In this particular case, medical billing experts should add:

• Patient identification details. 
• The procedural report (pre-procedure pain and the pain relief experienced post-procedure).
• Physician or medical health provider’s signature. 
• Imaging with at least two views of the final needle position with contrast flow documentation. Also, include the VAS pain score pre- and post-procedure.

Ensure Correct Code Application

Incorrect code application results in immediate claim denial, so billing experts should keep it in check. For instance, if the injection is administered in the thoracic or cervical area, CPT 62321 should be used instead. 

Check for Payer-Related Requirements

Every insurance payer may have its own requirements for claims and reimbursement. Therefore, the coding, billing, and supporting documentation should fulfil these requirements to reduce the chances of denial. 

Final Thoughts on CPT Code 62323

CPT code 62323 applies to a lumbar or sacral interlaminar epidural injection administered in the lower back. The procedure may be performed for treatment or diagnosis, depending on the scenario. We have covered all the essential information regarding this CPT code.
