CPT 85097: Bone Marrow Smear Interpretation, Pathology

CPT code 85097 represents the professional interpretation of a smear prepared from a bone marrow sample, typically performed by a pathologist. This diagnostic pathology service is critical for identifying hematologic disorders such as anemias, leukemias, and marrow infiltrative processes, making it an important code across inpatient and outpatient laboratory settings nationwide. Recognizing how 85097 is billed and reimbursed affects laboratory workflow, clinical documentation, and payer relations.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for bone marrow smear interpretation, common billing considerations, and benchmarks where available. The publication outlines the service setting and clinical implications, summarizes common modifiers and administrative practices associated with pathology interpretation services, and identifies gaps in available data.

This summary provides a national perspective on the role of 85097 in diagnostic pathways, the stakeholders responsible for reporting the service, and the operational touchpoints that influence billing and coding accuracy.

Billing Code Overview

CPT code 85097 describes the interpretation of a smear prepared from a bone marrow sample, a service typically performed by a clinician such as a pathologist. This service involves microscopic review and diagnostic interpretation of cellular morphology from bone marrow aspirate smears to inform hematologic diagnoses and guide clinical management.

Service type: Diagnostic pathology interpretation
Typical site of service: Hospital laboratory, outpatient pathology laboratory, or clinical pathology department where bone marrow samples are processed and reviewed

Clinical Context

A 62-year-old patient with persistent pancytopenia is referred for bone marrow evaluation. The hematology team performs a bone marrow aspiration and core biopsy in an outpatient ambulatory surgery or hospital inpatient setting. A pathologist prepares a bone marrow smear from the aspirate, examines the smear under light microscopy, and issues a diagnostic interpretation describing cellularity, lineage distribution, blast percentage, dysplasia, and any abnormal infiltrates or fibrosis. The report guides diagnosis and management of conditions such as myelodysplastic syndromes, acute leukemia, aplastic anemia, and marrow infiltration by metastatic malignancy. Turnaround includes correlation with peripheral blood smear, flow cytometry, cytogenetics, and molecular testing when ordered.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing the interpretation portion separately from technical services provided by the facility or laboratory.
`TC`	Technical component	Use when billing only the technical component (preparation and slide production) separate from the professional interpretation.

Taxonomy Code	Specialty	Notes
2080P0200X	Hematology	Hematologists frequently order and interpret marrow results and supervise clinical correlation.
207K00000X	Pathology	Clinical pathologists and hematopathologists perform smear interpretation and issue formal pathology reports.
2084P0800X	Oncology	Medical oncologists manage patients with marrow-involving malignancies and use interpretations for staging and therapy decisions.
207L00000X	Anatomic Pathology	Anatomic pathologists or hematopathologists perform morphologic assessment of bone marrow smears.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`C92.0`	Acute myeloblastic leukemia not having achieved remission	Bone marrow smear interpretation is essential for diagnosis, blast count, and guiding induction therapy.
`D46.9`	Myelodysplastic syndrome, unspecified	Smear morphology helps identify dysplasia and assess marrow cellularity in MDS.
`D61.9`	Aplastic anemia, unspecified	Marrow smear helps document hypocellularity and rule out infiltrative causes.
`C79.51`	Secondary malignant neoplasm of bone marrow	Smear can demonstrate metastatic involvement and guide staging and treatment.
`C91.00`	Acute lymphoblastic leukemia not having achieved remission	Smear interpretation contributes to lineage assignment and blast percentage necessary for treatment planning.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`85097`	Bone marrow smear interpretation by pathologist	Primary CPT code describing the professional interpretation of a marrow smear prepared from an aspirate.
`38220`	Bone marrow biopsy, needle or trocar; without aspiration	Often performed in conjunction with aspiration; provides core tissue complementary to smear interpretation.
`38221`	Bone marrow biopsy, needle or trocar; with aspiration(s)	Commonly billed when both core biopsy and aspirate are obtained; aspirate provides material for smear preparation.
