7. Help with Converting Codes
GEMs (General Equivalence Mappings) are a tool that can be used to convert data from ICD-9-CM to ICD-10-CM and vice versa.
Mapping from 10 to 9 is referred to as backward mapping while 9 to 10 is referred to as forward mapping
GEMs are a comprehensive translation dictionary that can be used to accurately and effectively translate any ICD-9-CM based data

8. Help with Converting Codes
GEMs (General Equivalence Mappings) can be used by anyone who wants to convert coded data, including:
All payers
All providers
Medical researchers
Informatics professionals
Coding professionals
Software vendors
Organizations
Others who use coded data

9. Help with Converting Codes
GEMs (General Equivalence Mappings) are not a substitute for learning how to use the ICD-10 codes.
More information about GEMs and their use can be found on the CMS website at:

10. October 1, 2014
Medical Coding in U.S. health care settings will change from ICD-9-CM to ICD-10
Compliance date is firm (no grace period, no delays)
ICD-10-CM diagnoses codes will be used by all providers in every health care setting
ICD-10-PCS procedure codes will be used only for hospital claims for inpatient hospital procedures
ICD-9-CM codes will not be accepted for services provided on or after

11. Check Your Understanding of Implementation Compliance Date

12. Important!!
ICD-10-CM codes will not be accepted for services prior to October 1, 2014
Providers must begin using ICD-10-CM codes to report diagnoses from all ambulatory and physician services on claims with dates of service on or after October 1, 2014, and for all diagnoses on claims for inpatient settings with dates of discharge that occur on or after October 1, 2014
ICD-10-PCS (procedure codes) must be used for all hospital claims for inpatient procedures on claims with dates of discharge that occur on or after

13. Benefits of ICD-10 Coding System
New Classification system will provide better data needed to:
Measure the quality, safety, and efficacy of care
Reduce the need for attachments to explain the patient’s condition
Design payment systems and process claims for reimbursement
Conduct research, epidemiological studies, and clinical trials

14. Benefits of ICD-10 Coding System
New Classification system will provide better data needed to:
Set health policy
Support operational and strategic planning
Design health care delivery systems
Monitor resource utilization
Improve clinical, financial, and administrative performance
Prevent and detect health care fraud and abuse
Track public health and risks

15. Differences from ICD-9-CM to ICD-10-CM
Overall number of codes is significantly increased from approximately 14,000 in ICD-9-CM to approximately 70,000 in ICD- 10-CM
ICD-10-PCS codes increased from approximately 4,000 in ICD-9-CM to approximately 70,000
ICD-10 codes are longer and use more alpha characters

16. Differences from ICD-9-CM to ICD-10-CM
Codes allow greater clinical detail and specificity in describing diagnoses and procedures
Terminology and disease classification have been updated to be consistent with current clinical practice
Last but not least is that system changes are required to accommodate the ICD-10 codes

21. Examples of ICD-10-CM Codes compared to ICD-9-CM Codes
Diabetes mellitus with retinopathy ICD-9-CM ICD-10-CM E

22. ICD-10-CM NEW FEATURES
Combination codes for conditions and common symptoms or manifestations
Combination codes for poisonings and external causes
Added laterality
Expanded codes (injury, diabetes, alcohol/substance abuse, postoperative complications)
Injuries grouped by anatomical site rather than injury category

23. Combination Codes
I Atherosclerotic heart disease of native coronary artery with unstable angina pectoris
E Type 2 diabetes mellitus with unspecified diabetic retinopathy with macular edema
K Crohn’s disease of small intestine with intestinal obstruction
N41.01 Acute prostatitis with hematuria
T57.0X4A Toxic effect of arsenic and its compounds, assault

24. Laterality
C Malignant neoplasm of lower-outer quadrant of right female breast
C Malignant neoplasm of lower-outer quadrant of left female breast
C Malignant neoplasm of lower-outer quadrant of unspecified female breast
C Malignancy neoplasm of lower-outer quadrant male breast

25. Increased Specificity
S72.044G Nondisplaced fracture of base of neck of right femur, subsequent encounter for closed fracture with delayed healing
I Sequelae of cerebral infarction, Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side
Z47.81 Encounter for orthopedic aftercare following surgical amputation
Z48.21 Encounter for aftercare following heart transplant

26. 7th Character Addition of 7th character :
Used in certain chapters to provide information about the characteristic of the encounter
Must always be used in the 7th character position
If a code has an applicable 7th character, the complete code must be reported with an appropriate 7th character value in order to be valid

27. Character “X”
Character “x” is used as a 5 character placeholder in certain 6 character codes to allow for further expansion and to fill in other empty characters when a code that is less than 6 characters in length requires a 7th character
T46.1x5A - Adverse effect of calcium channel blockers, initial encounter
T15.02xD – Foreign body in cornea, left eye, subsequent encounter

28. Two Types of Excludes Notes
Excludes 1 – Indicates that the condition excluded should never be used with the code noted in the note (do not report both codes)
Excludes 2 – Indicates that the condition excluded is not part of the condition represented by the code but a patient may have both conditions at the same time, in which case both codes may be assigned together (both codes can be used to capture both conditions)

29. Example of Excludes R22.2 Localized swelling, mass and lump, trunk
Excludes 1: intra-abdominal or pelvic mass and lump (R19.0-)
Excludes 2: breast mass and lump (N63)

30. Inclusion and Code Expansion
Inclusion of clinical concepts that do not exist in ICD-9-CM (e.g., underdosing, blood type, blood alcohol level)
A number of codes have been significantly expanded (e.g., injuries, diabetes, substance abuse, postoperative complications)

31. Examples of Expanded Codes
T45.526D – Underdosing of antithrombotic drugs, subsequent encounter
Z67.40 – Type O blood, Rh positive
Y90.6 – Blood alcohol level of mg/100 ml

32. Examples of Expanded Codes
E – Type 1 diabetes mellitus with diabetic neuropathic arthropathy
F – Alcohol abuse with alcohol- induced sleep disorder
T82.02xA – Displacement of heart valve prosthesis, initial encounter

33. Category restructuring and Code Reorganization
Injuries are grouped by anatomical site rather than by type of injury
Category restructuring and code reorganization have occurred in a number of chapters, resulting in the classification of certain diseases and disorders that are different from ICD-9-CM

34. Category restructuring and Code Reorganization
Certain diseases have been reclassified to different chapters or sections in order to reflect current medical knowledge
New code definitions (e.g., definition of acute myocardial infarction is now 4 weeks rather than 8 weeks)
The V codes and E codes are incorporated into the main classification rather than separated into supplementary classifications as they were in ICD-9-CM

35. ESSENTIAL DEFINITIONS
The Uniform Hospital Discharge Data Set (UHDDS) provides definitions for primary and secondary diagnoses.
Adapted to fit all non-inpatient settings (post- acute) such as home healthcare, hospice, nursing facilities, and rehab facilities.
In determining principal diagnosis/primary diagnosis, the coding conventions (instructional notes incorporated in the codes) take precedence over the Tabular and Alphabetic Index guidelines.

36. Primary Diagnosis
The condition that caused the admission for services.
That condition most relevant to the plan of care.
That diagnosis which represents the most acute condition and will require the most intensive services.

37. Secondary Diagnosis Co-Morbidities
Additional Diagnoses used in coding guidelines.
All conditions that coexist during the episode of care that may affect the plan of care or which developed subsequently and affect the treatment or care of the patient.
Entered on the OASIS C (OASIS C-1) in the order by the degree of which they will impact the plan of care and the need for homecare services.
Entered on the MDS only if active diagnoses and impact the plan of care.

38. Case-mix Diagnosis
A diagnosis related to the prospective payment system; may involve manifestation coding.
Medical record documentation must support the diagnosis reported on the OASIS-C and 485 and the MDS Assessment.

39. Hospital or Referral Diagnosis
The condition treated by the inpatient facility or by the physician in an outpatient setting relevant within the past 14 days.

40. Historical Diagnosis
Any condition that is resolved and is no longer being treated.
Appropriate for the OASIS C assessment but not the plan of care.
Not appropriate for MDS assessment.

41. LTC CODING SCENARIO

48. How to Prepare for Implementation
Learn about the structure, organization, and unique feature of ICD-10-CM
Learn about the system impact and 5010
Identify areas of strength/weakness in medical terminology and medical record documentation
Review and train to improve knowledge of medical terminology as needed

49. How to Prepare for Implementation
Provide intensive coder training approximately 3-6 months prior to implementation
Contact vendors to determine their state of readiness for implementation
Provide additional training to refresh or expand knowledge in the biomedical sciences (anatomy, physiology, pathophysiology, pharmacology, and medical terminology)

50. How to Prepare for Implementation
Communicate with all staff who will be impacted by the change to keep them updated and to make sure they understand their role in the transition
Work with physicians to make sure they understand some of the changes that will need to be made in documentation to allow for greater specificity in coding with ICD-10

51. Expect the Unexpected
Three variables which you can control or influence.
Human resources (coders, auditors, IT)
IT systems (internal/external)
Vendors
**Training
**Practice
**Keep current with industry
