CPT 88300: Level I Surgical Pathology — Specimen Accessioning and Gross Examination
Headline: CPT code 88300: Level I Surgical Pathology — Specimen Accessioning and Gross Examination
Lead: CPT code 88300 covers the level I surgical pathology service in which a physician, usually a pathologist, formally receives (accessions) a surgical specimen and performs a gross examination, documenting key features for diagnostic processing. This foundational step in surgical pathology is essential for accurate diagnosis and downstream laboratory processing.
What the code represents and national significance: CPT code 88300 identifies the basic surgical pathology encounter focused on specimen accessioning and gross evaluation. Nationwide, this service is a routine but critical element in the pathology workflow that influences diagnostic accuracy, turnaround time, and specimen triage for microscopic examination or ancillary testing.
Key payers covered: The analysis includes national commercial and public payers: Aetna; Blue Cross Blue Shield; Cigna Health; UnitedHealthcare; and Medicare.
What readers will learn: The publication explains clinical context for CPT code 88300, where the service is typically performed, and how it fits within the surgical pathology code family. Readers will find comparisons to higher-level surgical pathology services (e.g., level II–VI codes), descriptions of typical clinical scenarios and specimens, and information useful for coding, billing flow, and operational planning. Policy and benchmark content relevant to reimbursement classification and service definitions are also summarized.
Scope: This is a national overview intended for coding, billing, compliance, and pathology leadership audiences.

National Reimbursement Benchmarks
Medicare's mean rate for CPT 88300 sits at $11.3, while BUCA’s average commercial mean is notably higher at $26.2, indicating that commercial contracts captured by BUCA pay on average roughly $14.9 more than Medicare for this code. That gap highlights a meaningful premium in BUCA’s commercial portfolio versus the Medicare baseline.
Dispersion measured as the interquartile range (P75 minus P25) varies across payers: Blue Cross Blue Shield shows the widest IQR at $9.0 (P75 $42.0 minus P25 $30.1), followed by BUCA with an IQR of $13.0 (P75 $31.0 minus P25 $19.7) — actually indicating BUCA’s contractual spread is larger than BCBS when computed from provided quartiles. The tightest distributions are Aetna and UnitedHealth Group, both with an IQR of $9.0 and $8.8 respectively (Aetna $15.5–$6.0 = $9.5; UnitedHealth Group $14.8–$6.0 = $8.8), while Cigna’s IQR is $13.8 (P75 $18.8 minus P25 $5.4), reflecting substantial variation in Cigna contracts.
