What Q4249 covers
Q4249 represents the Amniply amniotic membrane product supplied for wound treatment, measured by the square centimeter. Wound-care clinicians, surgeons, and podiatrists may use it when applying the product to a prepared wound bed in an office or other treatment setting. The code identifies the product, not the wound preparation or application service itself.
Report the number of square centimeters represented by the Amniply product furnished, and retain documentation identifying the product and supporting the quantity reported. CMS classifies Q4249 as an add-on code: bill it only with a primary procedure, such as an applicable skin-substitute application procedure, and payment is within that procedure’s global period. It is a technical-component-only code; a separate code covers interpretation.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Q4249 billing questions
How is Q4249 different from the skin-substitute application code?
Q4249 reports the Amniply product by square centimeter. The primary application code reports the wound application service.
Can Q4249 be billed by itself?
No. CMS identifies Q4249 as an add-on code that must be billed with a primary procedure.
What quantity should be reported?
Report the square centimeters of Amniply product furnished. Documentation should identify the product and support the quantity.
Is a separate interpretation code needed?
CMS classifies Q4249 as technical-component-only and specifies that a separate code covers interpretation.
How does the global-period rule affect payment?
Payment for Q4249 is within the primary procedure’s global period, so it is not paid separately from that procedure’s global payment.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
