Operational Process to the CMG
• Pre-admission screening (screener/physician) Gather apparent Impairment Group Code Gather co-morbid conditions Age information Payer status (Medicare vs. other payer)
• Admission Physician assessment is done and H&P is written IRF-PAI is started once Impairment Group Code and co-
morbid conditions are confirmed with physician documentation
Therapy and nursing assessment are completed and plan of care is written
FIM motor subscale scores are obtained
Operational Process to the CMG
• Assessment Coders review charts at the end of the assessment to assign
admission codes Beginning CMG is established Discharge plan identified
• Concurrent coding Additional comorbidities and complications are added to the
IRF-PAI as per physician documentation
• Discharge Discharge destination selected Length of stay set Final coding is complete IRF-PAI is locked and transmitted UB-04 is sent to FI for payment

Simple Payment Determination
•Base Rate x CMG/Tier weight

Exceptions to full CMG Payment
•Transfer Rule Discharge to Medicare or Medicaid certified
facility And -
•Has a LOS shorter than the LOS for the CMG they were assigned when discharged
•Per diem payment for the days on the unit plus ½ the per diem for the first day
Transfer Rule Example
• Base Rate $13,241• Weight for CMG 108 Tier 3 = 1.8897• Weight times base rate = $25,021• LOS for CMG 108 Tier 3 is 25• CMG 108 Tier 3 divided by 25 = $1001/day• Times 8 days = $8006• Plus ½ one per diem = $8506
Transfer Process
•Works the same for transfers to:
Skilled Nursing Facilities & Nursing Homes Long Term Acute Care Acute Care Another Rehab Program
Program Interruption
•Program Interruptions include transfers to acute and back to rehab during the stay.
CMG includes paying for acute stays when:•Patient is discharged to acute and returns to IRF by
midnight of the 3rd calendar day.•All costs associated with the acute stay are
recorded on the rehab cost report.•True for discharges to acute care of your own
facility or acute care of another hospital.
Program Interruption
•Acute stay greater than 3 days are different. If patient goes to acute care and does not return by
midnight of the 3rd calendar day, discharge and re-admit.
Patient will have a new admission and assessment reference period.
New CMG will be assigned based on information gathered at admission.
Correct Coding
• Why Correct Coding is Important
Assignment of appropriate case mix group (CMG) Correct payment tier for co-morbidities Prevention of issues with potential Medicare
compliance audits Compliance with the “75%” rule
Accurately coding documented diagnoses allows for appropriate reimbursement and permits us to capture all
possible resources for our patients’ care.
Correct Coding
• Assignment of Rehab Impairment Code
Assign the group that best describes the primary condition requiring admission to the rehabilitation program.
•PPS Coordinator will look at the condition for whether or not it meets 75% rule compliance
•If not, look at the acute care documentation to determine what the patient was being treated for
•Is there an etiologic diagnosis that will qualify the patient?
Diagnosis Coding
• Etiologic diagnosisUse ICD-9 codes, but official coding guidelines do not apply
• Comorbid conditionsUse ICD-9 codes, official coding guidelines sometimes apply
Etiologic Diagnosis
• Etiologic diagnosis Diagnosis that led to condition for which the patient is
receiving rehabilitation
May use code for an acute condition causing the impairment
May use code for a late effect of an acute condition if a rehabilitation program was completed previously for same impairment
Co-morbidities
• Co-morbid condition Patient condition other than the impairment or etiologic
diagnosis Exists at the time of admission/may develop during stay Affects treatment received and/or LOS
• Co-morbid conditions should be reported if they require: Clinical assessment Additional diagnostic procedures Therapeutic treatment Extension of the length of stay Enhanced nursing care and/or monitoring
• List on IRF-PAI even if not in payment tier
Complications
• Complications are medical conditions
Not present at time of admission to rehabilitation
Identified during rehabilitation stay
That slow or compromise the rehabilitation program
Coding Complications
• Conditions occurring day prior to discharge or on day of discharge
Do not add to the burden of care, so they do not yield additional payment
Document conditions early or as identified rather than waiting until the discharge summary
Coding
•Coding the IRF-PAI and the UB-04 is not the same!
Common question: Should the codes on these documents be the same?
•NO!
Diagnosis Coding
Etiologic Diagnosis
The problem that lead to the impairment requiring rehabilitation
Using ICF terminology, the disease, disorder or injury that resulted in impairment
Principal Diagnosis
The circumstances of inpatient admission always govern the selection of principal diagnosis.
It is “that condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care"
Diagnosis Coding
IRF-PAI Coding
Etiology is selected by identifying the cause of the primary impairment
Acute Care Coding
Principal diagnosis is always a V57 code – Care involving use of rehabilitation procedures
V57.89 – Other specified rehabilitation procedure
Diagnosis Coding
IRF-PAI Coding
Limited to ten codes to report comorbid conditions
Acute Care Coding
Limited to spaces on the UB04 – eighteen spaces
Diagnosis Coding
IRF-PAI Coding
Codes should be sequenced according to PPS strategy:1.) tier assigning2.) conditions that affect the patient (increase need for heath care resources or LOS)3.) support medical necessity
Acute Care Coding
Codes are sequenced using specified procedures, software scrubbing
Diagnosis Coding
IRF-PAI Coding
Codes are reported for actively treated conditions, only. Do not code "probable", "suspected", "likely", "questionable", or "possible“ conditions
Acute Care Coding
If the diagnosis documented at the time of discharge is qualified as "probable", "suspected", "likely", "questionable", "possible", or "still to be ruled out", code the condition as if it existed or was established. The bases for this guidelines are the diagnostic workup, arrangements for further workup or observation, and initial therapeutic approach that correspond most closely with the established diagnosis.
Diagnosis Coding
IRF-PAI Coding
Late effect codes are used when the patient has completed a rehabilitation program for the condition in the past
Acute Care Coding
A late effect is the residual effect (condition produced) after the acute phase of an illness or injury has terminated. The residual may be apparent early, such as in cerebrovascular accident cases, or it may occur months or years later, such as that due to a previous injury
Diagnosis Coding
IRF-PAI Coding
Code significant symptoms that require health care resources
Code residual effects of the primary impairment treated in rehabilitation
Acute Care Coding
Signs and symptoms that are integral to the disease process should not be assigned as additional codes
Diagnosis Coding
IRF-PAI Coding
Code concurrently
Acute Care Coding
Recent change from coding at discharge to coding concurrently
Diagnosis Coding
IRF-PAI Coding
Coding may be done by HIM professional or by a clinician (PPS coordinator)
Acute Care Coding
Official rules for who does coding
Diagnosis Coding
IRF-PAI Coding
Do not code conditions that are recognized the day of discharge or the day preceding discharge
*Coding comparison from Dr. Pam Smith, Extreme Makeover for Medical Rehabilitation
Acute Care Coding
No stipulation on when a condition is identified
Documentation Tips
• In the H&P note all active conditions and plan to address the conditions
• Medication changes – document why changed
• Lab results – document decisions made based on lab results
• Ordering additional tests/labs – document reason why ordered,
discuss risks, advantages, hasten rehab participation and
discharge
Coding Points to Remember
• When in question, distinguish between obesity and morbid obesity
Involve dietitian Morbid obesity is a BMI of 40 or more
• Physician delineation of manifestations of diabetes mellitus assists coders
Peripheral neuropathy Nephropathy Retinopathy, etc.
