Summary & Overview
CPT 00872: Anesthesia for Extracorporeal Shock Wave Lithotripsy
CPT code 00872 covers anesthesia for extracorporeal shock wave lithotripsy (ESWL), a widely used procedure for treating kidney and ureteral stones. This code is significant in the national healthcare landscape, as ESWL is a common intervention for urinary calculi, requiring specialized anesthesia care to ensure patient safety and comfort. The code is most frequently billed in outpatient hospital settings, reflecting current clinical practice trends.
Major payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. The publication provides a comprehensive overview of payer coverage, typical billing practices, and relevant modifiers for anesthesia services associated with ESWL. Readers will gain insights into clinical context, associated diagnoses, and related CPT codes, as well as policy updates and benchmarks relevant to anesthesiology and urology service lines. The summary also highlights the importance of accurate coding and documentation for anesthesia services in outpatient procedures.
This article is designed for healthcare professionals, billing specialists, and policy analysts seeking up-to-date information on anesthesia coding for ESWL. It offers a clear breakdown of payer coverage, clinical indications, and coding nuances, supporting informed decision-making in medical billing and compliance.
CPT Code Overview
CPT code 00872 is used to report anesthesia services for extracorporeal shock wave lithotripsy (ESWL), a procedure commonly performed to treat urinary tract stones. This code falls under the anesthesiology service type and is typically provided in an outpatient hospital setting (Place of Service 22). Anesthesia for ESWL ensures patient comfort and safety during the non-invasive fragmentation of kidney or ureteral stones using shock waves.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting to the outpatient hospital with symptoms of kidney or ureteral stones, such as flank pain or hematuria. The patient is scheduled for extracorporeal shock wave lithotripsy (ESWL) to treat the urinary calculi. An anesthesiology provider evaluates the patient preoperatively, determines the appropriate anesthesia plan, and administers anesthesia during the ESWL procedure. The anesthesia may be provided by an anesthesiologist or a certified registered nurse anesthetist (CRNA), sometimes with medical direction by a physician. The procedure is performed in an outpatient hospital setting, and the patient is monitored throughout for safety and comfort.

Related Diagnoses
-
N20.0- Calculus of kidney- Indicates the presence of kidney stones, which are a primary indication for ESWL.
-
N20.1- Calculus of ureter- Indicates ureteral stones, another common reason for ESWL.
-
N20.2- Calculus of kidney with calculus of ureter- Represents patients with stones in both the kidney and ureter, suitable for ESWL treatment.
-
N20.9- Urinary calculus, unspecified- Used when the location of the urinary stone is not specified, but ESWL is still indicated.
-
Z48.89- Encounter for other specified surgical aftercare- Used for follow-up visits after ESWL, reflecting ongoing care post-procedure.

-
99100- Anesthesia for patient of extreme age, under 1 year and over 70- Used as an add-on code when the patient receiving ESWL anesthesia is of extreme age, indicating increased complexity.
-
99135- Anesthesia complicated by utilization of controlled hypotension- Used as an add-on code if controlled hypotension is employed during the ESWL procedure, reflecting additional anesthesia complexity.
-
99140- Anesthesia complicated by emergency conditions- Used as an add-on code when the ESWL procedure is performed under emergency conditions, indicating increased risk and complexity.
These codes may be used together with 00872 to reflect the clinical scenario and anesthesia complexity. 50590 is the primary surgical code, while 00872 is the anesthesia code. The add-on codes (99100, 99135, 99140) are applied as appropriate based on patient age, procedure complexity, or emergency status.
