| Procedure | Volume | Avg. paid | Avg. submitted |
|---|---|---|---|
| Tissue staining for diagnosis, additional An extra laboratory procedure to apply special stains to tissue slides for detailed examination. |
573 | $24 | $115 |
| Tissue pathology examination, moderate complexity A laboratory test where a pathologist examines tissue samples under a microscope to analyze cellular details. This intermediate complexity procedure involves specialized techniques to identify abnormalities in the tissue. |
489 | $31 | $153 |
| Cell examination with selective cellular enhancement A laboratory test that examines cells from a specimen using a technique to selectively enhance specific cellular features for detailed analysis. |
269 | $22 | $199 |
| Tissue staining for diagnosis, initial A laboratory test where special stains are applied to tissue slides to help examine the cells and identify specific characteristics. |
211 | $29 | $205 |
| Intraoperative pathology examination, first tissue block A pathologist examines a tissue sample removed during surgery to provide a preliminary diagnosis. This test is performed on the first tissue block obtained from the procedure. |
207 | $52 | $256 |
| Moderately high complexity pathology tissue examination A laboratory test where a pathologist examines tissue samples under a microscope to analyze cellular details. This specific level of complexity involves a moderate to high degree of technical skill and interpretation. |
153 | $69 | $340 |
| Fine needle aspirate evaluation and report A pathologist examines cells collected via a fine needle aspiration and provides a written interpretation and report of the findings. |
92 | $56 | $289 |
| Special stain test for organisms A laboratory test using special stains on tissue slides to identify microorganisms. The process includes the technical preparation of the slides and a professional interpretation of the results. |
75 | $22 | $109 |
| Pathology tissue examination, moderate complexity A laboratory test where a pathologist examines tissue samples under a microscope to identify abnormalities. This specific level indicates a moderate degree of complexity in the analysis. |
72 | $10 | $61 |
| Genetic sequencing localization, initial procedure This procedure involves the initial process of localizing genetic sequencing. It identifies the specific location of genetic material for further analysis. |
56 | $36 | $181 |
| Tissue preparation to remove calcium A laboratory procedure that removes calcium from a tissue sample to prepare it for microscopic examination. |
43 | $10 | $51 |
| Manual microscopic genetic analysis of tumor A laboratory test that uses a microscope to manually examine tumor tissue for genetic changes. |
40 | $33 | $225 |
| Surgical pathology consultation on referred slides A pathologist reviews and reports on tissue slides that were prepared at another facility. This service provides a second opinion or expert analysis of the existing samples. |
39 | $70 | $344 |
| Pap test A screening test to check for cervical cancer by collecting cells from the cervix. |
29 | $18 | $132 |
| Cell examination of specimen, concentration technique A laboratory test that uses a concentration technique to examine cells from a specimen. |
27 | $19 | $92 |
| High complexity pathology tissue examination A laboratory test where a pathologist examines tissue samples under a microscope using advanced techniques to analyze cellular details. |
27 | $122 | $598 |
| Limited pathology tissue examination A microscopic examination of tissue samples to identify abnormalities. This limited exam focuses on specific aspects of the tissue rather than a comprehensive analysis. |
22 | $4 | $19 |
| Special tissue stain and interpretation A laboratory test using special stains to examine tissue samples, including the pathologist's review and written report of the findings. |
21 | $10 | $49 |
| Surgical pathology consultation with slide preparation A specialist reviews tissue samples sent by another provider, preparing necessary slides for examination. The specialist then provides a diagnostic report based on this analysis. |
21 | $73 | $357 |
| Additional genetic sequencing localization This procedure involves additional genetic sequencing localization work beyond the initial test. It is performed to further analyze genetic material. |
15 | $29 | $140 |
| Fine needle aspirate evaluation A laboratory examination of cells collected via fine needle aspiration to assess for abnormalities. |
12 | $30 | $145 |
