Medical records must document that the ultrasound was limited to retroperitoneal structures when billing CPT 76770/76775/76776, including images/findings demonstrating limitation to the retroperitoneum.
If the exam was expanded to include organs outside the retroperitoneum, documentation must reflect the expansion and support billing a full or limited abdominal ultrasound (CPT 76700/76705/76706).
Claims and documentation should follow the complementary Local Coverage Determination L34577 and any applicable LCD requirements.
Claims must report the appropriate CPT code for the flow cytometry service, include 1 unit of service (UOS), and list the appropriate ICD-10-CM diagnosis code.

Retroperitoneal ultrasound (CPT 76770, 76775, 76776) is covered when the exam is limited solely to retroperitoneal structures.
A full (complete) or limited abdominal ultrasound (CPT 76700, 76705, 76706) is covered when the exam includes organs or structures outside the retroperitoneum or when primary findings involve non-retroperitoneal structures (e.g., gallbladder, liver, spleen, common bile duct).
Coverage and medical necessity determinations for flow cytometry are governed by Local Coverage Determination L34513.
Flow cytometry may be used to analyze cellular components of body fluids and lymphoreticular tissues, including peripheral blood, cerebrospinal fluid (CSF), bone marrow, lymph nodes, tonsil, spleen, and fine needle aspirate material.
Peripheral blood or fine needle aspirate specimens may be used to avoid more invasive diagnostic procedures when clinically appropriate.
CPT 88182 reports the physician professional and facility technical components of DNA ploidy and S-phase analysis of tumor by flow cytometry.
