Scrotal Ultrasonography — CPB 0532 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0532 governing scrotal ultrasonography coverage, effective November 27, 2025. If your team bills CPT 76870, this update to the Aetna scrotal ultrasonography coverage policy tightens the line between covered indications and what Aetna now explicitly labels experimental or unproven.

Aetna updated CPB 0532 in Aetna's clinical policy system to clarify medical necessity criteria for CPT 76870 (ultrasound, scrotum and contents). The changes sharpen two areas that routinely drive claim denial: infertility workups and testicular microlithiasis surveillance.

Aetna Scrotal Ultrasonography Coverage Criteria and Medical Necessity Requirements 2025

The core of CPB 0532 in the Aetna clinical policy system is a well-defined list of medically necessary indications for CPT 76870. Aetna covers scrotal ultrasonography when the clinical picture matches one of eight specific indications. Your documentation needs to map directly to one of them — "scrotal complaint" is not enough.

Aetna recognizes the following as medically necessary for CPT 76870:

Medical necessity documentation needs to be specific. A note saying "patient has scrotal pain" maps to N50.8x and supports coverage. A note saying "ordering ultrasound to work up infertility" walks right into the exclusion criteria — unless the exam documents why physical examination was difficult or inadequate.

This coverage policy does not explicitly list prior authorization requirements for CPT 76870. That said, prior auth requirements vary by Aetna plan product. Verify auth requirements at the plan level before scheduling, especially for elective indications like varicocele evaluation or infertility workup. Reimbursement exposure is real if auth is missed on a plan that requires it.

Aetna Scrotal Ultrasonography Exclusions and Non-Covered Indications

This is where CPB 0532 puts billing teams at risk. Two categories are explicitly labeled experimental, investigational, or unproven. Both are common ordering patterns that can look covered at first glance.

Infertility — initial evaluation without adequate clinical justification. Aetna considers scrotal ultrasonography experimental for the initial evaluation of infertility unless physical examination of the scrotum is difficult or inadequate, or a testicular mass is suspected. This is a narrow carve-out. If a urologist orders CPT 76870 as a routine first step in an infertility workup — without documenting a physical exam limitation or suspected mass — Aetna will deny it. The N46.x codes alone are not enough to get you paid.

The real issue here is documentation, not the indication itself. The order and the note must say why the exam was clinically necessary given physical exam findings. "Obese patient, scrotal exam limited" or "palpable firmness suggesting possible mass" — those phrases matter.

Testicular microlithiasis surveillance — without additional risk factors. Aetna considers ongoing surveillance for testicular microlithiasis experimental unless the patient has additional risk factors. Those risk factors are defined in the policy: a history of cryptorchidism, testicular atrophy (volume less than 12 ml), or previous testicular cancer. Surveillance ultrasounds for microlithiasis in an otherwise low-risk patient will deny.

This mirrors the same pattern Aetna has used in other imaging surveillance policies — coverage is not blanket, it's risk-stratified. If your practice does microlithiasis follow-up, your documentation must tie the order to one of those three specific risk factors. ICD-10 code N50.82 (scrotal pain) carries a policy note flagging it as not covered for testicular microlithiasis.
