CPT Code 88302: Complete Guide to Pathology Billing, Coding & Reimbursement in 2026

CPT 88302 looks like one of the simpler surgical pathology codes a gross and microscopic exam, one level up from the most basic pathology service. But accurate coding is only the starting point. Documentation quality, diagnosis linkage, specimen identification, and payer-specific claim requirements all affect whether that correctly coded claim actually gets paid.
CPT 88302 at a Glance Code category: Surgical pathology, Level II (part of the 88300–88309 code family). Service: Gross and microscopic examination of a specimen. Billing focus: Specimen-specific code selection, documentation completeness, diagnosis linkage. Unit of service: Per specimen, not per slide or per block. Common claim risk: Missing diagnosis code or incomplete gross/microscopic documentation. |
What Is CPT Code 88302?
88302 reports Level II surgical pathology — a specimen examined both grossly (visually, by the pathologist) and microscopically, used specifically to confirm identification of the specimen and the absence of disease. It sits one level above 88300 (gross examination only) and below the more complex 88304–88309 codes, which represent ascending levels of physician work for different specimen types.
What distinguishes 88302 from its neighboring codes isn't complexity in the abstract it's the specific specimen type. CPT assigns particular specimens to each level, and 88302 covers things like an incidental appendix, a fallopian tube removed for sterilization, traumatic finger or toe amputation, newborn foreskin, a hernia or hydrocele sac, nerve tissue, skin from plastic repair, and similar specimens. Code selection follows the specimen list, not a subjective complexity judgment.
What Does CPT 88302 Include?
The code covers accession, gross and microscopic examination, and reporting for the specimen — the full pathology workup for that one specimen type. It does not automatically include additional services like special stains, immunohistochemistry, or other procedures described in CPT 88311–88365 and 88399; those are reported in addition when actually performed, not bundled into 88302 by default.
Compliance Check Don't assume every related pathology service is separately billable just because it occurred alongside the 88302 exam. Review current NCCI edits and payer-specific bundling rules before reporting additional codes on the same claim. |
CPT 88302 Documentation Requirements
☐ Patient information and date of service
☐ Specimen identification, clearly matching the specimen type assigned to this code level
☐ Gross examination findings documented in the pathology report
☐ Microscopic examination findings documented in the report
☐ Clinical indication for the pathology service
☐ Diagnosis information supporting the claim
☐ Pathologist/provider documentation and sign-off
☐ Payer-specific documentation requirements checked
Incomplete or inconsistent documentation — a gross description present but no microscopic findings, or a specimen type that doesn't match the code level — is one of the more common sources of claim delay and denial for this code.

Common CPT 88302 Billing & Coding Mistakes
Issue | Billing Impact | Prevention |
Specimen doesn't match the 88302 specimen list | Code mismatch triggers review or denial | Confirm the specific specimen against the current CPT specimen assignment |
Missing diagnosis code | Surgical pathology claims without a diagnosis code are typically denied outright | Diagnosis coding reviewed before every claim submission |
Incomplete gross or microscopic documentation | Claim can't be defended as Level II if one component is missing from the report | Confirm both components are documented before coding |
Additional services bundled incorrectly | Separately billable services (88311–88365) missed or incorrectly combined | Review NCCI edits and payer policy before adding codes |
Duplicate billing | Same specimen billed more than once | Duplicate-claim check before submission |
Claims not followed up after rejection | Revenue sits unresolved in AR | Dedicated denial/rejection queue with follow-up timeline |
CPT 88302 Reimbursement in 2026
There's no single universal payment amount for 88302. Actual reimbursement depends on the payer, geographic locality, facility versus non-facility setting, contract terms, Medicare or commercial payer rules, documentation, and any applicable claim edits. A correctly selected CPT code doesn't by itself guarantee a specific payment — verify the current applicable fee schedule or contracted rate for the specific payer rather than relying on a general figure.
What Can Affect Payment |
Payer and plan type |
Geographic locality |
Contract terms |
Documentation completeness |
Coding accuracy and specimen match |
Applicable claim edits |
Payer medical policy |
Denial/appeal status |
CPT 88302 Denials: What Billing Teams Should Watch For
☐ Is the pathology documentation complete (both gross and microscopic)?
☐ Does the diagnosis support the service billed?
☐ Was the correct CPT code selected for this specific specimen?
☐ Were applicable payer requirements checked?
☐ Were coding edits (NCCI, payer-specific) reviewed?
☐ Was the claim submitted with accurate patient and provider information?
☐ Is the claim being monitored after submission, not just filed and forgotten?
CPT 88302 vs. Related Pathology Codes
The 88300–88309 family is a specimen-driven ladder, not a complexity scale you choose freely: 88300 covers gross-only specimens, 88302 covers specific Level II specimens requiring both gross and microscopic exam, and 88304–88309 cover progressively more involved specimen types at ascending levels of physician work. Selection should always follow the current CPT specimen assignment and the actual specimen examined — not an assumption based on how complex the case seemed clinically. Verify the current CPT code set and applicable coding guidance before finalizing any code in this family.

What is CPT 88302 used for?
It's used for specimens such as an incidental appendix, a fallopian tube removed for sterilization, traumatic finger/toe amputation, newborn foreskin, hernia or hydrocele sac, nerve tissue, and skin from plastic repair, among the specimens CPT assigns to this level.
How is CPT 88302 billed?
Per specimen, with accurate specimen identification, complete gross and microscopic documentation, and a supporting diagnosis code — claims without a diagnosis code are typically denied.
What documentation supports CPT 88302?
A pathology report documenting both gross and microscopic findings, specimen identification matching the code's specimen list, clinical indication, and diagnosis information.
How does reimbursement for CPT 88302 work?
Payment varies by payer, locality, contract, and documentation — there's no single universal rate, and the correct code alone doesn't guarantee a specific payment amount.
Why might a CPT 88302 claim be denied?
Common causes include a specimen that doesn't match the code's specimen assignment, missing diagnosis codes, incomplete gross or microscopic documentation, and coding edit conflicts.
