Check a contract rate as a % of Medicare · 00873 nationwide

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 00873 covers

This code covers anesthesia for extracorporeal shock wave lithotripsy (ESWL) performed without a water bath, commonly to treat kidney or ureteral stones. An anesthesiologist or CRNA provides and reports the anesthesia in an outpatient facility or office setting; the urologist reports the stone-treatment procedure, such as CPT 50590.

Choose this code when ESWL is performed without a water bath, rather than the water-bath service represented by 00872. The anesthesia record should document anesthesia start and stop times; the operative record should establish the stone site and that ESWL was performed without a water bath. This code has 5 base units, and Medicare payment is the sum of base units and time units multiplied by the locality's anesthesia conversion factor. Anesthesia time runs from preparation for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; CMS converts minutes to 15-minute time units to one decimal place, and the conversion factor varies by locality.
