(unknown) Effective Date: N/A Revision Date: N/A Surgery - Urinary System Feed
Excision of perinephric cyst.
Modifiers may be applicable.For example, modifier 22 (Increased Procedural Services) may be used if the procedure was significantly more complex than usual (e.g., due to extensive adhesions, unusual cyst size or location). Modifier 51 (Multiple Procedures) may apply if other procedures are performed during the same surgical session.
Medical necessity for 50290 is established when the perinephric cyst is symptomatic (e.g., causing pain, hydronephrosis, or other complications), is large enough to pose a risk of complications, or is suspicious for malignancy.Documentation should clearly support the medical necessity for the procedure.
The surgeon is responsible for prepping and anesthetizing the patient, making the incision, dissecting the perirenal muscles, fat, and Gerota's fascia, excising the cyst wall, flushing the site, obtaining tissue samples (if necessary), fulgurating any remaining cyst wall attached to renal connective tissue, suturing, inserting a drain (if necessary), controlling bleeding, and closing the incision.
In simple words: The surgeon removes a fluid-filled sac (cyst) from the area surrounding the kidney.This involves making an incision, carefully separating the cyst from surrounding tissues, removing it, and then closing the incision. A drain may be temporarily placed to remove excess fluid.
Surgical removal of a cyst located around the kidney, involving incision, dissection of perirenal muscles, fat, and Gerota's fascia, cyst wall excision, and potential drainage tube insertion.May include fulguration of cyst wall remnants, suturing, and bleeding control.
Example 1: A 45-year-old male presents with flank pain and a palpable mass. Imaging reveals a large perinephric cyst causing discomfort. The surgeon performs a 50290, excising the cyst and relieving the patient's symptoms., A 60-year-old female undergoes imaging for unrelated reasons, and a small, asymptomatic perinephric cyst is discovered. Due to the cyst's size and location, the surgeon recommends elective excision (50290) to prevent potential complications., A 2-year-old child is diagnosed with a large, complex perinephric cyst causing hydronephrosis. The surgeon performs a 50290 to remove the cyst and preserve kidney function.
Documentation should include patient history, physical exam findings, imaging results confirming the presence and characteristics of the perinephric cyst, operative report detailing the procedure (including size and location of the cyst, any complications), and pathology report (if tissue was sent for analysis).
