Summary & Overview
CPT 88155: Cervicovaginal Cytopathology Hormone Evaluation
Headline: CPT code 88155: Laboratory cytopathology analysis for hormone evaluation
Lead: CPT code 88155 identifies a technical laboratory procedure in which an analyst evaluates cervical or vaginal cytology slides to determine hormonal effects using indices such as maturation index, karyopyknotic index, and estrogenic index. The service supplements other technical and interpretation services and has implications for lab billing and clinical reporting nationwide.
What the code represents and why it matters: CPT code 88155 represents a specialized cytopathology technical service focused on assessing hormonal influence on cervical or vaginal epithelial cells. Nationally, it matters for laboratories and pathology departments that perform cytologic assessments as part of gynecologic evaluations, menopausal assessments, or hormone therapy monitoring.
Key payers covered: The analysis discusses payment and coverage considerations for major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Overview of what readers will learn: This publication provides benchmarks and context for CPT code 88155, summarizes clinical use and common sites of service, and outlines payer coverage scope and common modifiers used in practice. It also highlights where data is available and notes when input fields are missing.
Data availability: Data not available in the input for associated taxonomies, specific ICD-10 diagnoses, related codes, and detailed payer-specific rates.
Billing Code Overview
CPT code 88155 describes a technical laboratory procedure in which a lab analyst examines cervical or vaginal cytopathology slides to evaluate a patient’s hormonal status. The analysis may use methods such as maturation index, karyopyknotic index, and estrogenic index to provide a definitive assessment of hormonal effect on epithelial cells. This service is performed in addition to other technical and interpretation services coded separately.
Service Type: Laboratory cytopathology technical analysis
Typical Site of Service: Clinical laboratory or pathology laboratory
Clinical & Coding Specifications
Clinical Context
A 48-year-old female presents to a gynecologic clinic for evaluation of symptoms related to hormonal status, such as irregular vaginal bleeding, vaginal atrophy, or menopausal symptoms. The clinician collects a cervical or vaginal cytology specimen using a standard collection device (e.g., swab or cytobrush) and submits slides to the laboratory. A cytology laboratory analyst performs a technical cytopathology test to evaluate the patient’s hormonal effect on the epithelium using methods such as maturation index, karyopyknotic index, or estrogenic index. The analyst prepares, stains, and examines slides microscopically, documents cellular maturation patterns, and generates a technical report to support clinical interpretation. Results are transmitted to the ordering clinician, who integrates findings with clinical history (e.g., menopausal assessment, medication effects, or endocrine disorders) to guide management. Typical site of service is an outpatient gynecology clinic or hospital outpatient laboratory performing cytopathology assays; specimen processing occurs in a clinical laboratory setting equipped for slide preparation and microscopic analysis.
