Overnight test: After determination of baseline serum cortisol, 8 mg (typically) PO between 11:00 pm and midnight; cortisol level tested between 8:00 and 9:00 AM on following morning. IV test: After determination of baseline serum cortisol, 1 mg/hr by continuous IV infusion for 5-7 hours.
Simple: Surgical closure of a superficial wound, requiring single layer suturing of the. skin (epidermis, dermis, or subcutaneous tissue). Intermediate: 1) Surgical closure of a wound requiring closure of one or more of the. deeper subcutaneous tissue and non-muscle fascia layers in addition to the skin.
Once youve determined that the repair is simple, you would refer to codes 12001* through 12021 to choose the specific code by the length of the wound. However, according to CPT, a single-layer closure of a heavily contaminated wound that needs extensive cleaning would elevate it to an intermediate repair.
