What 88112 covers
This service involves preparing and interpreting a nongynecologic cytology specimen using selective cellular enhancement, such as a liquid-based slide preparation. Typical specimens include urine, bladder washings, pleural or peritoneal fluid, bronchial washings, and cerebrospinal fluid. In a hospital or independent laboratory, technical staff prepare the slide, a cytotechnologist may screen it, and a pathologist interprets the findings and issues a report.
Report one unit per specimen, not per slide. The report should identify the specimen source and preparation method so the selective-enhancement service can be distinguished from direct smears, filter preparations, and concentration techniques such as cytospin. Do not add a concentration code merely for a preparation step within the reported examination. CMS prices professional and technical components separately: modifier 26 identifies the pathologist’s interpretation, and modifier TC identifies the preparation, equipment, and staff work. Billing without either modifier represents the global service when both components are billed together.
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.

88112 billing questions
Can this code be reported for a ThinPrep Pap test?
No. Cervical and vaginal specimens use gynecologic cytopathology codes, such as 88142 for an applicable thin-layer preparation.
Is a cytospin preparation reported with this code?
A cytospin is a concentration technique generally reported with 88108. Use 88112 for a selective cellular enhancement preparation, such as an applicable liquid-based slide.
Can 88112 and 88108 both be billed on the same urine specimen?
Do not add 88108 merely because concentration was a step in preparing the specimen for the 88112 examination. Select the code that describes the cytology preparation and interpretation performed.
Is a cell block from the same fluid separately billable?
Yes, when a cell block is separately prepared and examined, report 88305 for the cell block in addition to the cytology service.
When should modifier 26 or TC be used?
Use modifier 26 when billing only the pathologist’s interpretation and modifier TC when billing only the technical work. Bill without either modifier when both components are billed as one global service.
How are units counted?
Report one unit per specimen, not per slide. Multiple slides from the same urine or fluid specimen do not add units.
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.
