What 88360 covers
This service includes immunohistochemical staining of tumor tissue and a pathologist's manual quantitative or semiquantitative assessment, rather than a qualitative interpretation alone. Common uses in breast carcinoma include estrogen and progesterone receptor scoring, HER2 membrane scoring on a 0 to 3+ scale, and the Ki-67 proliferation index. Hospital and independent pathology laboratories perform the staining; a pathologist assesses the stained cells at the microscope on a biopsy or resection specimen.
Report one unit for each single-antibody stain procedure scored manually on each separately evaluated specimen. If computer-assisted image analysis performs the quantitation, report 88361 instead. Do not add a qualitative IHC code for the same antibody stain procedure; qualitative stains using other antibodies may be reported separately when supported. Documentation should identify the specimen, antibody, manual scoring method, and result. CMS prices professional and technical components separately: modifier 26 identifies the pathologist's interpretation, modifier TC identifies the staining and other technical work, and the unmodified code represents both components when furnished by one billing entity.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

88360 billing questions
When is 88360 reported instead of 88342?
Use 88360 for documented manual quantitative or semiquantitative tumor IHC assessment, such as an ER percentage or HER2 0 to 3+ score. Use 88342 for the first single-antibody IHC stain procedure on a specimen when the work is a qualitative assessment.
How many units are reported for an ER, PR, and HER2 panel on one breast biopsy?
Report three units if each single-antibody stain procedure is manually scored on that specimen. Count a second separately evaluated specimen separately when those stains are also performed and scored on it.
Can 88342 or 88341 be billed with 88360 for the same antibody?
Do not add a qualitative IHC code for the same antibody stain procedure on the same specimen. Qualitative stains for different antibodies may be reported separately when supported.
What if image analysis software is used to score the stain?
Report 88361 instead of 88360 when computer-assisted image analysis performs the quantitative or semiquantitative assessment. Do not report both for the same stain procedure on the same specimen.
Which modifier does a hospital-based pathologist use?
When the hospital performs the technical work and the pathologist bills only for interpretation, the pathologist reports 88360 with modifier 26. Modifier TC identifies a separately billed technical component; an entity furnishing and billing both components reports the global service without either modifier.
What documentation supports 88360?
The report should identify the specimen and antibody, document manual quantitative or semiquantitative assessment, and give the score or measured result, such as the percentage of positive tumor nuclei.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
