AMPC Designation key terms

A standardized code set maintained by the American Medical Association that describes medical, surgical, and diagnostic services. Payers use these codes to determine reimbursement amounts for professional claims.

A code set with two levels. Level I consists of CPT codes, while Level II contains alphanumeric codes for supplies, drugs, and services not represented in CPT.

The diagnostic and inpatient procedure coding system used to report patient conditions. ICD-10-CM covers diagnoses in all settings, while ICD-10-PCS covers inpatient hospital procedures only.

A CPT code category used to report office visits, hospital visits, and consultations. Selection depends on documented elements such as medical decision making or time on the date of service.

A two-character code appended to a procedure code that clarifies or alters how the service should be interpreted. Common uses include indicating a distinct service or a reduced service.

A two-digit code identifying where a service was furnished, such as a physician office or outpatient hospital. The setting affects payment rates and coverage rules on the claim.

The standard paper claim form used to bill professional services to Medicare and most commercial insurers. It contains patient, provider, diagnosis, and procedure information in numbered fields.

The uniform institutional claim form used by hospitals and other facilities to bill payers. It reports facility charges, revenue codes, and type of bill information rather than individual professional services.

A statement from an insurer showing how a claim was processed, including allowed amounts, patient responsibility, and reasons for denial. It is not a bill but guides patient collection.

An electronic or paper document from a payer that accompanies payment and lists each claim, its adjudication status, and any adjustment reasons. Practices use it to post payments accurately.

A fixed dollar amount a patient pays at the time of service, as defined by the health plan. The practice collects it upfront and the plan pays the remaining allowed amount.

The percentage of allowed charges a patient owes after the deductible is met, as specified in the plan. For example, a plan may pay 80 percent and the patient owes 20 percent.

The amount a patient must pay out of pocket for covered services before the health plan begins paying its share. Practices verify remaining deductible during eligibility checks.

Money owed to the practice for services already rendered but not yet paid. Aging reports categorize this balance by how long it has been outstanding to guide collection efforts.

A claim submitted with all required and accurate information so that it can be processed without additional review or correction. Clean claims are paid faster and reduce rework.

A payer's refusal to pay all or part of a submitted claim, typically due to missing information, ineligibility, or coding issues. Denials must be tracked, corrected, and appealed within deadlines.

A formal request asking a payer to reconsider a denied or underpaid claim. It typically requires a written explanation, supporting documentation, and adherence to the plan's filing deadlines.

The determination that a service is reasonable and required to diagnose or treat a patient's condition. Documentation must support this standard because payers deny services deemed not medically necessary.

A payer edit pair that identifies code combinations typically not billed together, such as bundled services. Practices must understand these edits to avoid automatic claim denials.

Billing individual components of a procedure separately when a single comprehensive code should have been used. This practice can trigger payer audits and is considered improper billing.

Reporting a service with a higher-paying code than the documentation supports. It is a compliance risk that can result in recoupment, penalties, and exclusion from federal programs.

A federal law imposing liability on parties who knowingly submit false or fraudulent claims to government programs. Penalties include treble damages and per-claim civil monetary penalties.

The federal agency within the Department of Health and Human Services that investigates fraud, waste, and abuse in Medicare and Medicaid. It publishes work plans and compliance guidance for providers.

An organized set of policies, training, monitoring, and reporting structures a practice uses to prevent and detect violations of law. Seven core elements form the standard framework for medical practices.

The person responsible for overseeing a practice's compliance program, including policy development, staff education, and investigation of reported concerns. This role needs authority and direct access to leadership.

Legal safeguards that prohibit retaliation against employees who report suspected fraud or regulatory violations in good faith. Practices must maintain confidential reporting channels and non-retaliation policies.

A federal law establishing national standards for protecting patient health information and simplifying administrative transactions. It governs privacy, security, breach notification, and electronic data exchange.

Individually identifiable health information held or transmitted by a covered entity or business associate. It includes demographic data linked to a patient's condition, care, or payment.

The HIPAA principle that only the least amount of protected health information needed to accomplish a purpose should be used or disclosed. It applies to routine uses and disclosures.

A written contract between a covered entity and a vendor that handles protected health information on its behalf. It requires the vendor to safeguard data and report breaches.

A systematic review of medical records compared against billed codes to verify accuracy and documentation support. Audits identify overpayments, underpayments, and education opportunities for coders and clinicians.

A program that improves the clarity and completeness of provider documentation so it accurately reflects patient severity and services rendered. Better documentation supports correct coding, quality reporting, and payment.

Selecting a subset of claims or records for review to estimate overall compliance and error rates. Sample size and method must be defensible if results are extrapolated to a larger population.

Statistical projection of an audit sample's error rate onto a larger set of claims to estimate an overpayment. Payers use it in recoupment actions, so sample validity matters greatly.

The end-to-end process of scheduling, registration, coding, billing, payment posting, and collections that converts patient services into revenue. Each step affects cash flow and denial rates.

Confirming a patient's insurance coverage, benefits, and cost-sharing before or at the time of service. Accurate verification prevents denials caused by inactive coverage or unmet plan requirements.

A component of E/M code selection reflecting the complexity of problems addressed, data reviewed, and risk of complications. Higher complexity supports higher-level visit codes.

A four-digit code on institutional claims that identifies the type of facility charge, such as room and board or pharmacy. It is used with UB-04 forms rather than professional claims.

A unique identifier for human drugs, including the labeler, product, and package size. Providers report it alongside HCPCS drug codes to support accurate pharmacy billing.
