Coding Accuracy Self-Audit Checklist

Generate a coding accuracy self-audit checklist for a specific procedure type or service category. This prompt helps healthcare organizations build internal coding review processes that catch common coding errors before claims are submitted — improving clean claim rates and reducing audit risk.

This prompt helps healthcare coding teams generate a coding accuracy self-audit checklist using service type, CPT code range, care setting, specialty, and known coding issues as inputs — no patient records are entered. It produces a checklist covering pre-coding documentation review, principal diagnosis accuracy, procedure code accuracy, modifier application, E/M level verification, bundling and unbundling checks, medical necessity linkage, and high-risk coding areas for the specified service type. It is used by coders, CDI specialists, and revenue cycle compliance staff at outpatient clinics, physician practices, and hospital departments building internal quality review processes.

Constraints
This does not constitute medical advice. Follow HIPAA guidelines. Recommend consulting qualified healthcare professionals.
Never include actual patient Protected Health Information (PHI) in prompts or outputs.
Coding must reflect documented services only — coding for services not in the medical record is fraudulent billing.
NCCI edits and modifier policies change annually — verify all bundling rules against the current year's NCCI edits.
Tested Models

Uncertainty
If the specific CPT codes or service type is broadly described, generate a general coding accuracy framework and note that the modifier and bundling sections require customization based on the specific code set.
Scope
PHI-free admin only — use a BAA-compliant AI (e.g. BastionGPT or Azure OpenAI) for PHI.

You are an experienced medical billing specialist with expertise in CPT and ICD-10 coding, medical necessity documentation, and coding compliance.

Generate a coding accuracy checklist for:

Service context:
- Procedure / service type: [SERVICE_TYPE]
- CPT code range involved: [CPT_RANGE — e.g., 99213-99215, 27447, 93000]
- Setting: [INPATIENT / OUTPATIENT / OFFICE]
- Specialty: [SPECIALTY]

Known coding issues for this service type (if any):
[KNOWN_ISSUES — e.g., modifier 25 misuse, E/M level selection, unbundling]

Generate a coding accuracy checklist covering:

## Pre-Coding Documentation Review
Documentation elements that must be present before coding — medical record completeness check.

## Principal Diagnosis Accuracy
ICD-10 code selection verification: specificity level appropriate, correct code for the documented condition, sequencing correct for inpatient.

## Procedure Code Accuracy
CPT code selection verification: code matches the documented procedure, correct code version for the service year, any add-on codes required.

## Modifier Accuracy
Common modifier application verification for this service type: which modifiers are commonly required, which are commonly misapplied, NCCI modifier indicator rules.

## E/M Level Accuracy (if applicable)
For E/M services: medical decision-making components documented, total time documented (if time-based), level matches documentation.

## Bundling and Unbundling Check
CPT code combinations that are commonly bundled (cannot be billed separately) or commonly incorrectly unbundled for this service type — reference NCCI edits.

## Medical Necessity Linkage
Does each CPT code have a supporting ICD-10 code that establishes medical necessity? Are all diagnosis codes documented in the current encounter?

## High-Risk Coding Areas
Specific coding elements for this service type that are frequently the subject of payer audits or RAC/OIG scrutiny.

How to use this prompt

1

1. Build service-specific checklists for your highest-volume and highest-risk procedure types rather than a generic coding checklist — the specific errors differ significantly by service.

2

2. Incorporate the checklist into a pre-billing quality review for high-risk service types and for new coders working with complex procedure codes.

3

3. Update the checklist annually to reflect CPT code changes and NCCI edit updates.

Customization tips

Add 'Focus on [modifier 57 vs. modifier 25] for this specialty — this is the most commonly misapplied modifier in [surgical / E/M] coding.'
For hospital inpatient billing, add 'Include DRG validation: does the principal diagnosis support the assigned DRG? Are relevant complications and comorbidities (CCs/MCCs) coded?'
Append 'Add a reference section listing the top 10 NCCI bundling pairs for this service type — coders should have this reference available during chart review.'

Sample output

Mar 2026Advanced
Coding Accuracy Review — Outpatient Encounter Audit Encounter Reviewed: [Date of Service], Established Patient Office Visit Billing Provider: [Provider Name and Specialty] Codes Submitted: [CPT CODE], [HCPCS CODE], [CPT CODE] Audit Status: REVIEW REQUIRED FINDING 1 — [CPT CODE] (Evaluation and Management, Established Patient, Moderate Complexity) Documentation Assessment: SUPPORTED The medical note documents a detailed interval history, examination of two body systems with relevant findings, and medical decision making involving a new problem requiring additional workup and management of two chronic conditions. This level of service is appropriately supported by the documentation. FINDING 2 — [HCPCS CODE] (Annual Wellness Visit, Subsequent) Documentation Assessment: PARTIALLY SUPPORTED — Amendment Recommended The annual wellness visit note contains a health risk assessment, personalized prevention plan, and review of functional ability and safety screening. However, the required cognitive assessment screening (brief standardized tool result or documentation of "no concerns identified" for patients 65+) is not documented. This element is a required component for the AWV to be complete as billed. Required action: Physician to add addendum within 24 hours documenting cognitive screening result or clinical observation. Do not resubmit until addendum is complete. FINDING 3 — [CPT CODE] (Handling and/or Conveyance of Specimen) Documentation Assessment: NOT SUPPORTED FOR SEPARATE BILLING Specimen handling is not separately billable when the laboratory performing the testing is owned or operated by the billing provider's practice. Our contracted reference lab arrangement does not support separate billing of specimen handling. This code should be removed from the claim. Required action: Remove [HCPCS CODE] from claim before submission. Estimated savings from avoided denial: $18. REVISED CLAIM RECOMMENDATION: Submit [CPT CODE] and [HCPCS CODE] (with addendum). Remove [CPT CODE].
