(2022) CPT Code 88305 – Description, Guidelines, Reimbursement & Examples

CPT Code 88305 is used to report Dissect Surgical Pathology. Anatomical pathology concerns with examination of surgical specimens of tissues removed from living patients for the purpose of diagnosis of disease and guidance in the care of patients.

Underneath the description, coding guidelines, reimbursement and examples of CPT 88305.

88305 Code Description

Description of 88305 CPT Code: Level IV Surgical pathology, gross and microscopic examination.

In surgical pathology coding, specimens/container, bundling/unbundling, lymph node regional resection, tissue/procedure vs. diagnosis are the most challenging issues.

Underneath the key processes involved in surgical pathology for accurate coding of CPT code 88305.

Surgical Pathology

Examinations would be ordered as a gross and microscopic pathology examination or a gross and microscopic tissue exam.

Tissue Sections

Histologic sections of tissue are pfrocessed for microscopic viewing using either chemical fixation or frozen section.

Frozen section processing involves freezing the tissue and generating thin frozen slices of the specimen that are mounted onto glass slides. 


Tissue is placed in a container that has the tissue source, preoperative diagnosis, and patient identification information labelled on it. 

Specimens from different locations must be submitted in separate containers, each labelled with the source of the tissue. 

Phases Of Assignment

There are three main phases of CPT code 88305 assignment in surgical pathology.

Code Completion When The Pathologists’ Sign-Out

During code completion of CPT code 88305, the billing manager must notify the pathologist of any discrepancy and the presence of all chargeable items that were coded in the final report.
(See Annex for Gross and microscopic examination of Lipoma)

The Pathologist’s Report

Specimen assessment, which has the draft report after grossing and the final pathologists’ report, provides the ultimate CPT code.

The ultimate CPT code is totally at the discretion of the pathologists report, although some discrepancies in reporting can be expected in some scenarios.

If the add-on codes for additional procedures, special stains, and immunochemistry are not incorporated into the computer program, they should be included.

The Specimen’s Accession Preliminary Code

The primary goal of the specimen accession is to assign a unique surgical number for processing, diagnostic assessment, and filing based on the data provided in the requisition. 

Coding Guidelines For CPT 88305

Services include accession, examination, and reporting. They do not include the services designated in codes CPT 88311 through CPT 88365 and CPT 88399 that are coded additionally when provided.

The unit of service for code is the specimen.

A specimen is defined as tissue or tissues that is (are) submitted for individual and separate attention, requiring individual examination and pathologic diagnosis.

Two or more such specimens from the same patient (eg, separately identified endoscopic biopsies, skin lesions) are each appropriately assigned an individual code reflective of its proper level of service.

Any unlisted specimen should be allocated to the code which most closely reflects the physician work involved when compared to other specimens assigned to that code.

For example, there is larynx biopsy but no larynx polyp, hence the code for larynx biopsy can be assigned. 

Do not report 88305 CPT Code on the same specimen as part of Mohs surgery.

The pathologic analysis of the specimen is an inclusive component of Mohs surgery to be performed by the surgeon and should not be reported separately by him.

If the Mohs surgeon submits a specimen(s) derived from the procedure for pathologic examination to another physician (i.e., a pathologist) for either frozen (CPT 88329 – CPT 88334) or permanent section (CPT 88305), the pathologist is allowed to report his or her services, but the procedure no longer qualifies as Mohs surgery.

The surgeon should report for excision and repair using the appropriate codes.

CPT Code 88305 Reimbursement Medicare

Underneath Medicare reimbursement for CPT 88305 for inpatient & outpatient visits, hospital services non and hospital based outpatient providers.

Inpatients & Outpatients Reimbursement

CPT code 88305 is coverd by medicare when coded for inpatient and outpatient visits. The physician professional fee component is covered by the Medicare Part B Physician Fee Schedule. 

Coverage of the technical component is decided by the provider and patient setting. 

Reimbursement For Hospital Based Services

CPT Code 88305 can be reimburst for hospital based services. The technical component is bundled into prospective payment plans with a single fixed payment based on the diagnosis-related group (inpatients, Medicare Part A) or the Ambulatory Payment Classification (hospital-based outpatient services, Outpatient Prospective Payment System).

Non Hospital Based Outpatient Providers Reimbursement

Reimbursement for 88305 CPT for non hospital based outpatient providers is as follows. The technical component is paid according to the Clinical Laboratory Fee Schedule under Medicare Part B; the fee schedule for clinical laboratory tests will be based on median private payer rates.

The technical component is billed on the date the specimen was collected. This would be the surgery date. 

When billing a global service, the provider can submit the professional component with a date of service reflecting when the review and interpretation is completed or can submit the date of service as the date the technical component was performed. This will allow ease of processing for both Medicare and the supplemental payers. 

If the provider did not perform a global service and instead performed only one component, the date of service for the technical component would the date the patient received the service and the date of service for the professional component would be the date the review and interpretation is completed. 

When the collection spans two calendar dates, use the date the specimen collection ended.

CPT Code 88305 Examples

Example 1

One Container, two skin biopsies, one with a suture.

Units of Service = 2 units 

Rationale : If the requisition confirms the significance of the suture (e.g., “sutured biopsy from right shoulder; second biopsy from right arm”), the physician work associated with each of these would be reported as two units of service.

Example 2

A patient’s colonoscopy yielded three endoscopic biopsies. Each is in its own container, which is labelled with the place of origin (e.g., hepatic flexure, descending colon, and rectum).

CPT 88305 X3 Units 

Rationale: Each is a separate specimen and the physician service related to each would be coded as CPT Code 88305 (three units of service).
