    Study Notes

    ICD-10-CM Official Guidelines for Coding and Reporting

    • FY 2025 - Updated October 1, 2024 (October 1, 2024 - September 30, 2025)
    • Narrative changes are in bold text
    • Italics are used to indicate heading revisions
    • Underlined items have been moved within the guidelines since the April 2024, FY 2024 version
    • CMS (Centers for Medicare & Medicaid Services) and NCHS (National Center for Health Statistics), within the U.S. Federal Government's Department of Health and Human Services (DHHS), provide guidelines for ICD-10-CM coding and reporting.
    • The ICD-10-CM is a morbidity classification used by the United States for classifying diagnoses and reasons for visits in health care settings.
    • The ICD-10-CM is based on the ICD-10, the statistical classification of diseases published by the World Health Organization (WHO).
    • Guidelines are approved by the Cooperating Parties: AHA (American Hospital Association), AHIMA (American Health Information Management Association), CMS, and NCHS.
    • Guidelines complement the ICD-10-CM, with the conventions and instructions of the classification taking precedence.
    • HIPAA (Health Insurance Portability and Accountability Act) requires adherence to assigned ICD-10-CM diagnosis codes in all healthcare settings.
    • Accurate coding requires complete documentation of the medical record in detailing the reason for the encounter and the treated conditions.
    • The term "provider" in the guidelines refers to physicians or other qualified healthcare practitioners legally accountable for patient diagnoses.
    • Guidelines are organized into sections: Section I (conventions, general coding guidelines and chapter-specific guidelines), Section II (selection of principal diagnosis for non-outpatient settings), Section III (reporting additional diagnoses in non-outpatient settings), Section IV (outpatient coding and reporting), for a full comprehension.

    Conventions, general coding guidelines and chapter-specific guidelines

    • Conventions applicable to all health care settings

    • Guidelines should follow conventions and instructions in the ICD-10-CM Tabular List and Alphabetic Index, including notes.

    • Codes for categories, subcategories, and codes in the Tabular List may be letters or numbers only.

    • Categories are 3 characters; subcategories are either 4 or 5 characters, and codes are 3, 4, 5, 6 or 7 characters.

    • The ICD-10-CM uses an indented format for easy referencing.

    • For reporting purposes only codes—not categories or subcategories—are permissible and any applicable 7th character is required.

    • Placeholders are used for codes that require future expansion (e.g., "X").

    • Punctuation symbols (e.g., brackets, parentheses) are used for abbreviations, synonyms, or explanatory phrases in the Alphabetic Index and Tabular List.

    • Other and Unspecified codes ("Other" codes use when detail is available but specific not and "Unspecified" codes use when insufficient detail to give specific code) are used when information is not detailed for specific code.

    • Includes notes and the list of terms under certain codes to provide further detail, may include synonyms or additional codes for that code.

    • Excludes notes are of two types that indicate independence and exclusivity (e.g., “Excludes 1” and “Excludes 2” notes).

    Etiology/manifestation convention ("code first")

    • When conditions have underlying etiology and multiple manifestations due to the etiology, code first the etiology followed by the manifestation.
    • Codes for manifestations often include the phrase "in diseases classified elsewhere".
    • Codes for manifestations are used in conjunction with the underlying condition.

    "And" and "With"

    • "And" can mean "and" or "or" in the title and "with" or "in" mean associated with or due to.
    • For conditions that are related, these terms indicate a causal relationship; documentation of a linkage is not essential.

    Additional topics

    • Code assignment based on provider documentation, not clinical criteria
    • Locating a code in the ICD-10 CM (use Alphabetic Index and Tabular List)
    • Diagnoses are sequenced in the maximum detail possible
    • Reporting signs and symptoms (when diagnosis is not established from provider)
    • Coding for multiple conditions and their relationship
    • Combination codes
    • Sequela (Late Effects)

    Reporting Same Diagnosis Code More Than Once

    • A code for a single condition must be reported only once per encounter/visit.
    • This applies to bilateral conditions that lack specific codes distinguishing laterality.

    Laterality

    • When laterality is documented (left, right, bilateral), use the appropriate code.
    • Use unspecified side code only when sufficient information is absent or contradictory.
    • Multiple encounters require individual codes for each side.

    Code assignment based on clinicians other than the patient's provider

    • Code assignment is based on provider documentation (physician or qualified healthcare practitioner).
    • Exceptions may occur based on documentation from other clinicians (e.g., dietitian, nurse).
    • Provider queries may be necessary.

    Other topics

    • Impending/threatened conditions
    • Coding for healthcare encounters in Hurricane Aftermaths
    • External cause of morbidity codes
    • Sequencing of external causes of morbidity codes.
    • Other issues related to external cause of morbidity codes.
    • Chapter-specific coding guidelines.
