Cheat Sheet

  1. ICD-10 Code Structure & Conventions -

    Every ICD-10 code starts with a letter, followed by two digits for the category, a decimal, then up to four alphanumeric characters for specificity, as defined by the CDC's official guidelines. For example, "M54.5" denotes low back pain (M = musculoskeletal, 54 = back pain category, .5 = low back). Remember the mnemonic "ABC.D" to recall letter, two digits, decimal, and detail characters.

  2. Using the 7th Character Correctly -

    The 7th character (e.g., A, D, S) indicates initial encounter, subsequent encounter, or sequela, per CMS Chapter 4 guidelines. For instance, "S52.521A" is a greenstick fracture of the right radius, initial encounter. Try the phrase "A New Situation, D Days Later, S Still Follows" to lock in those values.

  3. Sequencing & Diagnostic Priority -

    ICD-10-CM coding practice questions stress placing the principal diagnosis first, followed by coexisting conditions that affect treatment, consistent with AHIMA standards. In a pneumonia admission, J18.9 (pneumonia) leads, then E11.9 for comorbid diabetes. Always review Official Coding Guideline I.C.2 to sequence correctly in scenarios with multiple pathologies.

  4. Documentation & Clinical Indicators -

    Accurate coding hinges on clear documentation: signs vs. symptoms, confirmed vs. suspected conditions, as per AAPC best practices. If the record states "rule out MI," you'd code R94.31 (abnormal cardiac enzyme) instead of I21 (acute MI). Always cross-verify notes with lab values or imaging reports to choose the right code.

  5. Practice Strategies for Mastery -

    Regularly tackle icd-10 coding scenarios with answers and download icd-10-cm practice questions and answers PDF files from reliable sources (e.g., AHA). When you encounter "true or false: icd-10-cm provides procedure codes for services provided," recall that ICD-10-CM is strictly diagnostic; CPT/ICD-10-PCS cover procedures. Time yourself to simulate exam conditions and track your accuracy improvements.
