Title: ICD-10-CM – A Piece of Cake

ICD-10-CM (International Classification of Diseases – 10th Revision – Clinical Modifications) Session: T-5-1330

pre quiz

Quiz – jot down your answers

  • ICD-10-CM is:
    • ICD-9-CM where they replaced the three digit categories with three digit alpha-numeric categories to have more space
    • Pretty much volumes 1 and 2 of ICD-9-CM (volume 3 is now ICD-10-PCS)
    • Mapped to ICD-9-CM with about 95% of the codes being a one-to-one mapping
    • All of the above
pre quiz3
  • When you think “Personal History of” you think:
    • V10 – Personal History of malignant neoplasm, through V15 Other Personal History Presenting Hazard to Health
    • V86 Estrogen Receptor Status
    • V87 Other specified personal exposures and history presenting hazards to health
    • V88 Acquired absence of other organs and tissue
    • Both a and c even though they are not in the same place – this just makes coding more challenging!
pre quiz4
  • The coding guidelines for ICD-10-CM (e.g., assign all the digits available) are:
    • Are pretty much the same as for ICD-9-CM
    • Are pretty much the same as for ICD-8-A
    • Are pretty much the same as for ICD-7
    • Are pretty much the same as for ICD-6
    • All of the above
pre quiz5
  • The ICD-9-CM codes are being “frozen” (will not change, no additions/deletions) in 2012 because:
    • There is so much automation and all those programs need to have all the code numbers for the various conditions changed, tested, fixed, tested…
    • To give coders an entire year to goof off claiming they were studying VERY hard to understand the ICD-10-CM
    • Because the cost of gasoline had gone up to $3/gallon and those of us driving up from Washington to Baltimore for the Coordination and Maintenance Meetings wanted a break for an entire year
    • Because we knew Congress was looking to cut funding so long as it was not their pet project, so we coders squirreled away the funding somewhere else and said the codes were “frozen” so they would not take the money to maintain the code set
pre quiz6
  • The General Equivalency Mappings (GEMs) don’t have a one-for-one mapping because
    • Some few medical concepts have changed so the ICD-10-CM reflects the thought process of the current medical understanding
    • ICD-10-CM has expanded some concepts so it may have five codes while ICD-9-CM only has one code
    • If there was a one-for-one mapping to ICD-9-CM from ICD-10-CM, and a one-for-one mapping to 10 from 9, why bother with ICD-10?
    • All of the above
    • None of the above
pre quiz7
  • I plan to get ready for the new codes:
    • On 1 Oct 2013 and not a second before
    • When I take the Oct 2013 AHIMA CCS-P quiz I will borrow a book and hope for the best
    • I’d be willing to attend tele-classes for a few weeks prior so long as they let me do it from work
    • What – you silly goose, who actually believes the MHS will be ready on 1 Oct 2013, they can’t even get the new codes out until Jan/Feb/Mar on a normal year – I’m sticking with the MHS and plan never to have to learn the new codes
    • Other:

Know that ICD-10-CM transition will be easy for coders

Understand the General Equivalency Mappings

Know the coding guidelines for ICD-10-CM

icd 10 cm
  • Why
  • How – Direct Care
    • Issue: CAPER diagnosis field is only 7 characters
    • Issue: SIDR diagnosis field is only 8 characters
    • Issue: AHLTA
    • Issue: CCE
    • Issue: All the other direct and purchased care MHS systems/programs using ICD codes
  • Training Proposal Development
    • Coders
    • Providers
    • Data Analysts
difference between icd 10 cm icd 10 pcs and icd 9 cm
Difference Between ICD-10-CM, ICD-10-PCS and ICD-9-CM
  • International Classification of Diseases – 9th Revision – Clinical Modifications (ICD-9-CM)
    • Developed in USA in 1970s based on the World Health Organization’s ICD-9
      • Based on ICD-8 and ICD-8a
    • Clinical Modifications (CM) is the United States’ version
      • Added to WHO ICD-9:
        • External Causes of Injury
        • Factors Influencing Health
        • Volume 3, Institutional Procedure Coding
icd 10 cm11
  • ICD-10-Clinical Modifications is for use in the United States
    • Other countries use modifications specific to their country, such as ICD-10-CA for Canada and ICD-10-AM for Australia
  • ONLY:
    • Diagnoses,
    • Factors Influencing Health, and
    • External Causes of Injury
  • Does not include procedures as did ICD-9-CM
    • No third volume
    • See ICD-10-Procedure Classification System
  • Currently used for cause of death reporting in the United States
icd 10 cm12
  • Available for download from:
    • At the bottom of the page
  • A bit easier and less expensive than going to Ingenix and buying it on disc for $119.00
  • Would recommend buying one book every other year until 2013 as books are much easier to work with if that is what you are used to
  • The downloads are nice for a quick word search
icd 10 cm is better due to
ICD-10-CM Is Better Due To:
  • Addition of information relevant to ambulatory and managed care encounters
    • Expanded injury codes
  • Creation of combination diagnosis/symptom codes to reduce the number of codes needed to fully describe a condition
  • Addition of a sixth and seventh character for some codes
  • Laterality; and
  • Greater specificity in code assignment for many codes
  • The new structure will allow further expansion than was possible with ICD-9-CM
icd 10 cm14
  • “Piece of Cake” for anyone who can code using ICD-9-CM
    • Same basic guidelines
    • Same basic layout/organization
    • Same basic index
    • Same basic tabular
    • Some codes are more detailed
    • Some codes indicate initial or subsequent encounter
    • Format: alpha + 2 numerics + decimal point + numeric + 3 alphanumerics
      • H66.9 Otitis media, unspecified
        • Otitis media NOS
        • Acute otitis media NOS
        • Chronic otitis media NOS
      • H66.90 Otitis media, unspecified, unspecified ear
      • H66.91 Otitis media, unspecified. right ear
      • H66.92 Otitis media, unspecified, left ear
      • H66.93 Otitis media, unspecified, bilateral
review of existing code formats
Review of Existing Code Formats
  • ICD-9-CM diagnoses (look for the decimal point)
    • 3-5 numeric characters with decimal point after the 3rd
    • External cause of injury Exxx.x
    • Factors influencing health Vxx.xx
  • ICD-9-CM procedure (look for the decimal point)
    • Numeric xx.xx
  • CPT – 5 numeric, or 4 numeric with terminal F or T (no decimal point)
  • HCPCS – alpha with 4 numeric (no decimal point) – does not currently use F or T

coding guidelines
Coding Guidelines

Same – Look it up in the alphabetic, then check in the tabular

Same – Abbreviations

Same – Punctuation

Same – use of “and,” “with,” “see,” “see also”

Same – other and unspecified codes

Same – includes notes and inclusion terms

Same – etiology/manifestation (code first, use additional code, in disease classified elsewhere)

Same – must use all available characters

Same – conditions that are or are not an integral part of the disease process

coding guidelines31
Coding Guidelines

Same – Acute and Chronic conditions

Same – Late Effects (sequela)

Same – Human Immunodeficiency Virus (HIV) coding

Same – Treatment directed at malignancy

Same – Treatment of secondary site of maligancy

Same – Primary malignancy previously excised

Same – Admission/Encounter for chemo

Same – Hypertension

Same – Acute myocardial infarction

Same – Coding Pathologic Fractures…

coding guidelines32
Coding Guidelines

New – placeholder “x” if the code only has 4 or 5 characters, but needs a 7th character (e.g., initial/subsequent/sequela to injury), use an “x” in the blank spaces

Different – Exclude1 (never code it here) and Exclude2 (not included, if he has that, code it separately)

New – Laterality

New – Coding pregnancy trimesters

New – Glasgow coma scale

New – Functional quadriplegia

coding guidelines33
Coding Guidelines
  • Aftercare – Official Coding Guidelines
  • Section I, C, 21, c, 7) Aftercare
    • The aftercare Z codes should also not be used for aftercare for injuries. For aftercare of an injury, assign the acute injury code with the 7th character “D” (subsequent encounter).
  • Z51.89 – Encounter for other specified aftercare
review icd 10 cm
Review ICD-10-CM

Diagnoses, not procedures

Very similar to ICD-9-CM diagnoses, volumes 1 and 2 (diagnosis index and tabular)

Up to 7 alphanumeric characters


If you can code with ICD-9-CM, you can easily transition to ICD-10-CM


MHS is working on the transition

The transition will be most difficult for the software programs

ICD-10-CM is much better than ICD-9-CM

Coders will not have a problem transitioning from ICD-9-CM to ICD-10-CM


Take the quiz again

  • Questions?
  • Training
    • Who needs ICD-10-CM training?
    • When (e.g., 2 months prior)?
    • Intensity (e.g., 1 hour teleclass a day with 1 hour a day at work to do the assigned lessons)?
    • Format (e.g., train-the-trainer to come back to work to train you, teleclasses, one REALLY large class [400 students in an auditorium], good teacher sent to each site for a week)?
