Explanation

Updated October 26, 2026

Growth hormone exercise stimulation test with the physician present. The fee includes the venipunctures.

What it covers

G358 is the growth hormone exercise stimulation test, performed with the physician present (J41). It is listed under Endocrinology and Metabolism after the glucagon tests but is its own listing, not a type of glucagon test (G494, G495).

The fee includes the venipunctures needed for the test (J41).

Billing rules

  • The physician must be present for the test (J41).
  • Venipunctures are included, so don't bill G480, G482 or G489 for the test samples (J41).
  • G358 is not marked (+), so G700 doesn't apply (J3, J41).
  • Payable in addition to a consultation or assessment at the same visit (J3).

Often billed with

  • A003 or A007, or a specialist consultation, at the visit where the test is done (J3).
