XTRAC

Question:

Our practice is considering using XTRAC for patients with psoriasis. Before we purchase the laser, we want to make sure we get paid. Is there a CPT code for XTRAC?

Answer:

There is a CPT code for XTRAC, an excimer laser treatment for psoriasis. There are actually three codes: 96920, 96921, and 96922. The codes are selected by square centimeter size. CPT 96920 is reported for 250 square centimeters or less, 96921 when the total area treated is 250 to 500 square centimeters, and 96922 for treated areas over 500 square centimeters. The side of the treated area must be included for CPT codes that are reported based on centimeter or square cm size documentation.

Evacuation of Recurrent Subdural Hematoma and Drain Placement

Question:

A patient returns two weeks after evacuation of a chronic subdural hematoma with a recurrence requiring another evacuation of the hematoma and placement of a subdural drain. What are the correct codes to report for the evacuation of the hematoma and placement of the drain?

Answer:

CPT code 61312 for re-do craniotomy for hematoma with modifier 58 appended for a more extensive procedure treating the same problem during the global period.  The drain would not be separately reported.

Converting Dimensions

Question:

My surgeon placed integra and dictated the integra dimensions in inches instead of centimeters. Can the inches be converted into centimeters to determine code selection?

Answer:

Thank you for your inquiry.  

From a best practice standpoint, the physician is encouraged to document the size based on CPT requirements, e.g. centimeters in this scenario.  The risk is that an error may be made in performing the conversion if this activity is not regularly performed.

Use of Robotic Systems During Surgical Procedures

Question:

What is the code for a robotic procedure?

Answer:

When surgical procedures involve the use of robotic surgical systems, the robotic component can be represented by HCPCS code S2900.  However, there is no RVU associated with this code, and it is not reimbursed under the Medicare payment system.   The best practice is to set a fee for the extra physician work involved with robotic assistance, document medical necessity for the use of the robot, and incorporate this code into billing for tracking purposes when used.

Stratum Corneum

Question:

What CPT code do I use for the sampling of the Stratum Corneum?  I have searched everywhere and cannot find a code.

Answer:

The sampling of the stratum corneum by any method, is not a biopsy. Skin scraping or tape stripping is not considered a biopsy and should be credited as part of the E/M service.

Collagen Dressings

Question:

Our physicians would like to start using and billing collagen dressings for all post-surgical patients in the global period to aid with healing and have the dressings shipped directly to the patient and used at the patient’s home. What are the coding and billing requirements for reporting the service?  

Answer:

Thank you for your inquiry.  Several factors have to be considered.

First, using collagen dressings for routine dressing changes (e.g., all patients, as noted in the inquiry) during the global period would not meet the LCD requirements for payment consideration.

Routine dressing changes during the global period are included in the global surgical package per Medicare and, therefore, would not be separately reimbursable.

Per Medicare Claims Processing Manual, Chapter 12, Section 40.1

o   Miscellaneous Services - Items such as dressing changes; local incisional care; removal of the operative pack; removal of cutaneous sutures and staples, lines, wires, tubes, drains, casts, and splints; insertion, irrigation and removal of urinary catheters, routine peripheral intravenous lines, nasogastric and rectal tubes; and changes and removal of tracheostomy tubes.

Second, suppose the clinic wants to utilize these collagen dressings for routine postoperative patients during the global. In that case, the clinic will need to either absorb the cost and provide it to the patient or obtain an ABN or waiver from the patient advising them it is a non-covered service and give them the option if this is an item they would like to pay for out of pocket.  Depending on medical necessity, the dressings may or may not be covered under a home health benefit.

Medicare has an LCD—Surgical Dressings (L33831), with specific medical necessity requirements for coverage and payment. As with all reported services, medical necessity and the required reporting criteria must be documented.

Per Medicare LCD L33831:

Collagen Dressing or Wound Filler (A6010, A6011, A6021 – A6024)

A collagen-based dressing or wound filler is covered for full-thickness wounds (e.g., stage 3 or 4 ulcers), wounds with light to moderate exudate or wounds that have stalled or not progressed toward a healing goal.  They can stay in place for up to 7 days.  Collagen-based dressings are not covered for wounds with heavy exudate, third-degree burns, or when active vasculitis is present.

To justify payment for DMEPOS items, suppliers must meet the following requirements:

• Standard Written Order Criteria (SWO)

• Medical Record Information (including continued need/use if applicable)

• Correct Coding

• Proof of Delivery

Medicare reimburses surgical dressings under the Surgical Dressings Benefit. This benefit only covers primary and secondary surgical dressings used on the skin of specified wound types.

Refer to the related Policy Article NON-MEDICAL NECESSITY COVERAGE AND PAYMENT RULES for information about these statutory requirements.

LCD L33831 (Surgical Dressings) and Coverage Policy Article A54563 for complete details for reporting surgical dressings. 

https://www.cms.gov/medicare-coverage-database/view/lcd.aspx?lcdid=33831

As with all reported services, medical necessity and the required reporting criteria must be documented. If all Medicare LCD requirements are not met, an ABN would need to be obtained. Check your private payor policies for coverage. KZA does not recommend billing the patient for Collagen dressings for routine wounds if medical necessity is not met (e.g., all postoperative patients).
