Never used alone as a diagnosis code.6Diagnosis Codes: The ICD-9-CM(cont.)ICD-9-CM CONVENTIONSA list of abbreviations, punctuation, symbols, typefaces, and notes that provide guidelines for using the code set. ConventionsNOSAn abbreviation that means “not otherwise specified”, or “unspecified”NECAn abbreviation that means “not elsewhere classified”. This is used when the ICD-9 does not provide a specific code to describe the patient’s condition.[ ]Brackets are used around synonyms, alternate wording, or explanations. ( )Parentheses are used around alternative wordings. 7Diagnosis Codes: The ICD-9-CM(cont.)ICD-9-CM CONVENTIONSA list of abbreviations, punctuation, symbols, typefaces, and notes that provide guidelines for using the code set.

What does this mean?This means the medical assistant must look up the term that follows the word “see” because another category should be used or cross-referenced.- Answer13Procedure Codes: The CPTThe Current Procedural Terminology (CPT) book is the most commonly used system for reporting procedures and services provided to the patient.This is the HIPAA required code set.Published annually by the American Medical Association (AMA).14Procedure Codes: The CPTUsing the CPTExcept for the first section, the reference book is arranged in numerical order.SectionRange of CodesEvaluation and Management99201-99499Anesthesiology0010-01999Surgery10021-69990Radiology70010-79999Pathology and Laboratory80048-89356Medicine90281-9960215Add-On CodesA plus sign (+) is usedModifiersOne or more two-digit numbers are added with a hyphen after the five digit numberCategory II, III, and Unlisted Procedure CodesCategory II (tracks healthcare performance measures)Category III (temporary codes)Unlisted Codes (Used when no other code is adequate)Procedure Codes: The CPT (cont.)16Evaluation and Management ServicesExplains how to code different levels of patient services based on:Procedure Codes: The CPT (cont.)The extent of the patient history takenThe extent of the examination conductedThe complexity of the medical decision madeNew Patient versus Established Patient New patients have not been seen by physician within the past 3 years. Established patients have been seen within a 3 year period.17Surgical ProceduresThe “Surgical Pack” is a combination of services needed for surgery such as:AnesthesiaSurgeryRoutine Follow-Up CareGlobal Period refers to the time period that follow-up is rendered following surgery.Procedure Codes: The CPT (cont.)18Laboratory ProceduresPanels listed in Pathology and Laboratory sections of the CPT include tests commonly performed.If the panel code is not used and separate codes are used, they will be rebundled.ImmunizationsInjections require two codes, one for the procedure (injection) and the other for the medication (vaccine or toxoid)Procedure Codes: The CPT (cont.)19HCPCSThe Health Care Common Procedure Coding System (HCPCS)Developed by the Centers for Medicare and Medicaid Services (CMS)Pronounced “hic-picks”Contains two levels:Level I codes duplicate CPT codesLevel II codes are national codes covering suppliesContains 5 characters, either numbers, letters, or a letter with a number.20Avoiding Fraud: Coding ComplianceMedical assistants help ensure that maximum appropriate reimbursement for services provided are received.Compliance with federal and state law and payer requirements is mandatory.Code LinkageDiagnosticProceduresThis is a process that insurance company representatives use to evaluate the necessity of medical procedures that are reported based on the patient’s diagnosis.Careful attention to details are needed to prevent errors in coding and incorrect billing.21Avoiding Fraud: Coding Compliance(cont.)Insurance FraudInvestigators look for patterns such as:Reporting services that were not performed.Reporting services at a higher level than was carried out.Performing and billing for procedures that are not related to the patient’s condition and therefore not medically necessary.Billing separately for services that are bundled in a single procedure code.Reporting the same service twice.22Compliance PlansTo avoid the risk of fraud, medical offices incorporate a process for finding, correcting, and preventing illegal medical practices. A compliance officer and committee will:Audit and monitor complianceDevelop written policies and procedures that are consistent with regulations and lawsProvide ongoing communication and training to staffRespond to and correct errorsAvoiding Fraud: Coding Compliance(cont.)23The insurance representative has questioned the codes listed on three patient forms that were submitted last year. When re-checking these forms the office medical assistant should:Use the current book to validate accuracy of the codes.Use last year’s book to validate accuracy of the codes.Use next year’s book to validate accuracy of the codes.
