How this category is built

HCPCS Level II codes are organized by their first letter, which is how the range hubs on this site group them, but one kind of item or service often spans several letters: wheelchairs sit in the E and K ranges, supplies in A, B, Q and T, and imaging in A, C, G, Q and R. This hub regroups the codes by the BETOS category CMS records for each code in the HCPCS file, splitting the large prosthetic and orthotic category by L-code range and keeping vision and hearing items apart, so each non-drug code belongs to exactly one category hub besides its range hub. The national Medicare amount comes from the 2026 physician fee schedule, DMEPOS, clinical laboratory, OPPS or ASC file that prices the code, as on its reference page.

Where QuickIntell fits for other diagnostic tests

QuickCode supports qualified coder review of units, modifiers and NCCI pairs before the claim leaves, and QuickAuth coordinates requirement checks and documentation for items and services that a coverage policy governs, each with human review.

Frequently asked questions

Which HCPCS codes are grouped under "Other diagnostic tests"?

23 active Level II codes in the October 2026 file, grouped here by BETOS T2 (electrocardiograms, stress tests, monitoring and other tests). 12 have a full reference page; the table lists those and the collapsed list names the rest.

What is a BETOS category?

The Berenson-Eggers Type of Service classification groups HCPCS and CPT codes into broad clinical categories such as evaluation and management, procedures, imaging, tests and durable medical equipment. CMS carries a BETOS code for each Level II code in the HCPCS file, which is what this hub reads.

Which code in this category has the highest Medicare amount?

Among the codes with an indexed page, G0398 at $220.60 (OPPS rate), from the October 2026 files. Each code page shows the full breakdown by modifier, state or locality.
