What Q4246 covers
Q4246 identifies Coretext or Protext, with the reported quantity measured in cubic centimeters. Each unit represents 1 cc; report units according to the volume furnished. This distinguishes it from codes that identify other named products or use area-based or half-cc measures. Q4245 identifies Amniotext per cc, Q4247 identifies an Amniotext patch per square centimeter, Q4240 identifies Corecyte topical only per 0.5 cc, and Q4242 identifies Amniocyte Plus per 0.5 cc. The product name and unit basis therefore matter when selecting among these codes.
Medicare assigns Q4246 physician fee schedule status C (carrier priced): the Medicare Administrative Contractor (MAC) determines payment for each claim, using physician fee schedule contractor pricing. Medicare coverage is left to the MAC’s judgment. CMS classifies the code as technical-component-only, and a separate code covers interpretation. The reporting unit is one cc, so the number of units follows the cc quantity furnished.
