What 88161 covers
This service covers making cytology smears from a non-gynecologic specimen and examining them for cellular abnormalities, with interpretation and a report. A cytotechnologist commonly performs the technical preparation and screening, with a pathologist providing professional interpretation. Specimens may include sputum or urine; cervical and vaginal specimens use their own code family. The service may be performed in a hospital or independent pathology laboratory.
Choose this code when the laboratory prepares the smear as well as screens and interprets it. The record should identify the specimen source and support the preparation and cytologic evaluation performed. CMS recognizes separate professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff work, and billing without either modifier represents the global service.
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.

88161 billing questions
How does this differ from 88160?
88161 includes laboratory preparation of the smear as well as screening and interpretation. Use 88160 when the service is screening and interpretation without the preparation included in 88161.
Is slide preparation included?
Yes. Preparation of the smear, screening, and interpretation are part of this service; do not separately report the smear preparation as a second service under this code.
Can the professional and technical work be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical work, including equipment and staff. Without either modifier, the claim represents the global service.
Can this code be used for a Pap smear?
No. Cervical and vaginal cytology belongs to the cervicovaginal code family, such as 88142, rather than the other-source smear family.
What should the documentation identify?
Document the specimen source and the smear preparation, screening, and interpretation performed. That information supports distinguishing this service from screening and interpretation of an already-prepared smear.
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.
