Medicare usually does not reimburse routine healthcare services, which also include routine foot care. However, if you are providing foot care services to treat a foot disease or another medical condition, you can claim your reimbursement by applying the correct modifiers.
Modifiers Q7, Q8, and Q9 are vital modifiers in podiatry billing. Applying them correctly can ensure proper reimbursement and help prevent claim denials. How? These podiatry modifiers allow you to demonstrate the medical need for the service. So, in today’s blog, we will explain how you can bill your routine foot care services with the Q8 modifier and what the correct ways are to apply the modifier to a claim.
Q8 Modifier – Description
Let’s begin with the description of this modifier. The Q8 modifier is an HCPCS modifier used to report two class B findings. Class B findings include:
- Absent posterior tibial pulse
- Advanced trophic changes (at least 3 of the following), such as:
- hair growth (decrease or absence)
- nail changes (thickening)
- pigmentary changes (skin discoloration)
- skin texture (thin and shiny)
- skin appearance (rubor or redness)
- Absent dorsalis pedis pulse
More precisely, the Q8 modifier states that routine expert foot care is medically necessary to reduce the risk of injury or infection. Therefore, this modifier is applicable if the patient has any of the two conditions listed above.
What is Routine Foot Care and Why is it Not Covered?
Routine foot care services include:
- Trimming, cutting, clipping, or debriding of toenails
- Removing or cutting corns or calluses
- Hygienic and preventive maintenance care, like:
- Soaking and cleaning the feet
- Applying skin creams to maintain skin tone and texture
- Other foot services rendered in the absence of illness, injury, or symptoms
The services listed above are typically not covered by Medicare (and most commercial payers) because these are viewed as hygienic or cosmetic services, rather than medically necessary treatments.
Appropriate Use Cases for Q8 Modifier
Here are some real-world examples of how healthcare providers may use the Q8 modifier for podiatric billing.
Diabetic Patient with Peripheral Neuropathy
Suppose a 68-year-old male patient who has a long-standing Type 2 diabetes comes with a thickening of his opaque toenail with pain and numbness in his feet. The physician analyzes the condition of his feet and discovers peripheral vascular disease (PVD), which resulted in impaired circulation in the lower limbs and an absent pulse.
The physician decides to debride his toenail to avoid any further fungal infection. He can bill this service with the Q8 modifier to show the medical necessity of the procedure. Note that the patient’s diabetes and PVD are qualifying systemic diseases.
Psoriasis
Suppose a 64-year-old patient with a history of severe psoriasis comes for the debridement of a thick nail. The patient also exhibits trophic skin changes, such as dry and scaly skin, indicating impaired blood circulation. In this case, the patient has a systemic condition: psoriasis, and two verified Class B findings: missing pedal pulses and trophic skin changes. The podiatrist must apply the Q8 modifier to bill his services because two qualifying Class B findings were present.
Accurate Usage Guidelines for Q8 Modifier
Now we will discuss the accurate and inaccurate uses of the Q8 modifier, along with some additional compliance policies.
Apply Modifier Q8 Correctly
The Q8 modifier is used to explain that foot care was not routine or for cosmetic purposes, but was a requirement for the patient’s health. Your claim must clearly demonstrate that the patient has a condition so severe that foot care is medically necessary.
The most common health problems that necessitate foot care services, like nail debridement, include diabetes, nerve or vascular damage in the feet, or blood-related issues. The physician’s notes must clearly explain why the care was required, with appropriate Class B findings and the condition associated with them.
Avoid Inaccurate Uses of Modifier Q8
Append modifier Q8 to the claim if two Class B findings were observed. In case of one Class A finding, report modifier Q7, and Q9 if the patient had one Class B and two Class C findings.
It is inevitable to receive a denial if the Q8 modifier is applied to the claim without the provision of detailed documentation. Note that this results in failure to establish medical necessity for the services. To avoid such errors, you must ensure an internal audit system for your claims.
Ensure Compliance with Payer Policies
Every insurance payer has unique guidelines and requirements for billing and modifiers. Therefore, modifiers must also be used correctly in compliance with the payer’s specific policies. We advise that before billing and filing your claims with the Q8 modifier, you must verify each payer’s policies to avoid rejection.
Final Thoughts
Podiatrists must become proficient in the accurate usage of the Q8 modifier, as it will help them prevent payment delays and denials. Therefore, we have provided two specific examples of when to use modifier Q8 along with accurate usage guidelines. To appropriately charge Medicare for medically essential foot care services, follow our recommendations!
