CPT 88305: Surgical Pathology, Level IV Tissue Examination
CPT code 88305 represents Level IV surgical pathology, encompassing both gross and microscopic examination of tissue specimens. This procedure is a cornerstone of diagnostic medicine, enabling pathologists to identify and characterize disease processes from biopsies and surgical samples. The code is widely used across hospital and independent pathology laboratories, reflecting its national importance in clinical workflows.
Major payers covering this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a comprehensive overview of payer coverage, typical sites of service, and the clinical context in which 88305 is applied. Readers will gain insights into current policy updates, reimbursement benchmarks, and the role of surgical pathology in patient care. The analysis also highlights common modifiers and related codes, offering clarity on billing practices and procedural distinctions. This summary serves as a resource for understanding the operational and financial landscape surrounding surgical pathology services, with a focus on the national scope and payer diversity.
CPT Code Overview
CPT code 88305 is used to report Level IV surgical pathology procedures, specifically for the gross and microscopic examination of tissue specimens. This code is commonly utilized in pathology laboratories, including hospital-based and independent labs, typically at place of service codes 19 or 22. The procedure involves a detailed evaluation of tissue samples to assist in the diagnosis and management of various medical conditions, making it a critical component of clinical care.
Clinical & Coding Specifications
Clinical Context
A patient presents with a suspicious lump in the breast. The surgeon performs a biopsy and submits the tissue specimen to the pathology laboratory. In the lab, a pathologist conducts a gross and microscopic examination of the specimen to determine if the lesion is benign, malignant, or of uncertain behavior. This process is coded as 88305, representing a Level IV surgical pathology service. The workflow typically involves specimen collection in a hospital or independent laboratory (place of service 19 or 22), followed by detailed analysis and reporting by an anatomic pathologist.
Coding Specifications
| Modifier Code | Description | Usage Scenario |
|---|---|
| 26 | Professional component | Used when only the pathologist's interpretation/report is billed, not the lab's technical work |
| TC | Technical component | Used when only the laboratory's technical work (processing, staining, etc.) is billed |
| 22 | Increased procedural services | Used when the procedure requires significantly more effort or complexity than usual |
