R74.8 — Abnormal levels of other serum enzymes
ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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.
- The submitted medical record must support the selected ICD-10-CM code(s), and the submitted CPT/HCPCS code must accurately describe the service performed.
Key Coverage Criteria
- 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).
- For tests that currently lack specific CPT codes (functional intracellular analysis and total antioxidant function), bill using CPT 84999 and add a note identifying which test was performed in the Remarks area for Part A claims and the Narrative area for Part B claims.
- Coverage and reasonable/necessary determinations for assays for vitamins and metabolic function are governed by LCD L34914 and claims must meet that LCD's requirements to be covered.
- Esophagogastroduodenoscopy (EGD) is covered when it meets the reasonable and necessary requirements specified in Local Coverage Determination L33583.
- EGD is covered for persistent upper abdominal distress (e.g., gastroesophageal reflux disease) that continues despite an appropriate trial of symptomatic therapy.
