| Procedure | Volume | Avg. paid | Avg. submitted |
|---|---|---|---|
| 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. |
2,946 | $32 | $123 |
| Flow cytometry, additional marker An additional marker is tested during a flow cytometry procedure to analyze DNA or cells. This step adds specific data points to the initial analysis. |
2,836 | $18 | $62 |
| 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. |
1,206 | $56 | $206 |
| 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. |
938 | $59 | $224 |
| Additional manual multiplex genetic stain A microscopic genetic analysis performed manually using an additional multiplex stain procedure on tissue. |
783 | $287 | $1,125 |
