CPT 36620 is
listed in the CPT book as a “separate procedure*,” indicating it should not be
unbundled from a global service. Therefore, 36620 should not be unbundled.
*From the CPT
Expert, 2004 edition, published by the AMA:
procedures are services that are commonly carried out as an integral part of a
larger service, and as such does not warrant separate identification. These
services are noted in the CPT book with the parenthetical phrase (separate
procedure). When this phrase appears before the semicolon, all indented
descriptions that follow are covered by it.
procedures are often improperly reported as related procedures. Related
procedures are performed for the same diagnosis and within the same operative
area. Reporting a separate procedure in addition to the larger procedure to
which it is related is improper. A separate procedure can be a component of, or
incidental to, a larger, related procedure.”
investigation, it is clear that 36620 are not held to be a portion of any
anesthetic base code. Therefore, it is billable as a separate procedure by
anesthesiologists intending to use the arterial line for monitoring of blood
pressure or arterial oxygenation during an anesthetic. Because anesthesiologists
are generally paid in base and time units, this code will normally have to be
billed separately, with the anesthesiologist’s medical provider number, to allow
it to pay correctly.
