MDC




Major Diagnostic Category (MDC)

            The Major Diagnostic Categories (MDC) are formed by dividing all possible principal diagnoses (from ICD-9) into 25 mutually exclusive diagnosis areas.

            The diagnoses in each MDC correspond to a single organ system or etiology and in general are associated with a particular medical specialty. MDC 1 to MDC 23 are grouped according to principal diagnoses.

            Patients are assigned to MDC 24 (Multiple Significant Trauma) with at least two significant trauma diagnosis codes (either as principal or secondaries) from different body site categories.

DRG



Diagnostic Related Groups (DRG)
            A grouping of disease and disorders into medically meaningful sets as developed by the Centers for Medicare & Medicaid Services (CMS).

            This reimbursement system consists of established payment levels for groupings of patients according to medically meaningful characteristics. There are six major criteria, which are utilized in assigning a particular admission to a specific DRG.
        
    These consist of:

            - Patient's principal diagnosis

            - Procedures performed on the patient

            - Patient's age

            - Patient's gender

            - Patient's discharge status

            - Multiple diagnoses, complications or comorbid conditions.

HOSPITAL COURSE: The patient was admitted to the hospital for bed rest, hydration, monitoring of blood pressure and pain medication. The orthopedic surgeon examined the patient and concurred with diagnosis of femoral neck fracture of the right hip. Performed a hemiarthroplasty and found an additional fracture of the greater trochanter – patient tolerated the procedure well. The patient had significant pain after the surgery and experienced severe blood loss anemia following surgery. Transfusion of packed cells was given and patient improved. Blood pressure fluctuated slightly and was controlled well with medication.

On postoperative day two, patient underwent paracentesis for removal of 2.5 liters of ascites. Postoperative course was further complicated by the rise in ammonia. This came down with Lactulose.

Patient was discharged to the subacute unit for physical therapy. To be maintained on a low salt diet with moderate fluid restriction.


HISTORY AND PHYSICAL

REASON FOR ADMISSION: Fracture of right hip

HISTORY OF PRESENT ILLNESS: A 84 year-old-female was walking down the stairs at home when she tripped and fell, landing on her right side. She believed she broke her hip. Unable to walk and in severe pain she called her family and they brought her to the hospital.

Examination and x-ray determined a right hip fracture of the femoral neck with severe osteoarthritis of the same hip.

PAST MEDICAL HISTORY: Significant for long standing alcoholic liver disease with cirrhosis and ascites. And he was found to have massive ascites.

SOCIAL HISTORY: Lives alone with her many cats.

REVIEW OF SYSTEMS: Massive ascites, liver spans about 2-3 fingers below costal margin and is firm.

PHYSCIAL EXAMINATION: Well-developed female in considerable distress due to fall. Blood pressure 180/110, pulse 88, marked muscle wasting.

IMPRESSION:
1. Femoral neck fracture of right hip secondary to fall at home
2. Dehydration
3. Chronic cirrhosis


PROGRESS NOTES

DAY 4 – Pain is much better
Compression stockings in place
Anemia stable
Ammonia level within normal limits, abdomen less tense

DAY 5 – Discharge to subacute unit for physical therapy


OPERATIVE REPORT

NAME OF OPERATION: Hemiarthroplasty of right hip

DESCRIPTION OF PROCEDURE: An incision was made centered over the greater trochanter, carried down to the skin, subcutaneous tissue, fascia lata, and incised in line with the femur. Following this, the posterior aspect of the hip is exposed and the short external rotators are dissected sharply from the proximal femur, and the piriformis is also incised and saved for later repair. Incision retractor is placed. Following this, the fracture is identified and the femoral head is delivered from the acetabulum after opening the capsule in a T fashion.

At this point, the attention was turned to the fracture and the fracture was somewhat lower than originally expected and the attempt was made to broach the femur for the hemiarthroplasty. It was noted that there was an additional fracture, which was present on the lateral aspect of the trochanter and this later was significant to the point where it was felt that it required cable fixation. At this point the greater trochanter was reducted and a trochanteric claw is utilized to grasp the trochanter and this is affixed with 2 cables. A 3rd cable is placed over the main fracture. Satisfactory fixation was accomplished.

At this point, the leg was rolled 90 degrees, the foot was raised 90 degrees to the floor and the broaching was done utilizing a 10 Biomet fracture stem and the broach was positioned appropriately. At this point, the cement was mixed and the cement was passed into the proximal femur and the 10 Biomet fracture stem was inserted, approximately 6-7 degrees of femoral anteversion. The standard was perhaps too tight and a –3 was placed and the hip was stable with flexion and internal rotation. Following this the hip is prepared and the cement is dried and the –3 head is placed and the biopolar is assembled and a 47 outer bearing is placed. The hip is located and again there is good stability. The capsule is repaired utilizing #0 Vicryl. The piriformis is repaired utilizing #1 Vicryl. The fascia lata is closed utilizing a running double #1 Vicryl. The subcutaneous tissue is closed, the deep tissue with 0 Vicryl, the more subcutaneous tissue with 2-0 Vicryl and the skin with skin clips. Hemovac was placed in the depths of the wound and the soft compression dressing was applied. The patient was placed in an abduction pillow and rolled supine and then was awakened and taken to the recovery room.

Replacement was 2 units of packed red blood cells. Additional 2 units are available. The patient will have a repeat hemoglobin and hematocrit in the recovery room. The patient was given Ancef at the start of the case and at the end of the case and this will be continued postoperatively.

Cardiac Resynchronization Therapy



Types of Cardiac Resynchronization Therapy(CRT-P / CRT-D) Coding


What is CRT?

Cardiac resynchronization therapy (CRT) is a newer generation of pacemakers and AICDs. Its distinguishing feature is an extra lead at the left ventricle, in addition to the leads at the right atrium and/or the right ventricle used with conventional pacemakers and AICDs.

CRT is also known as biventricular therapy because, with one lead at the right ventricle and another at the left ventricle, it coordinates the pumping action of the ventricles.

There are two types of cardiac resynchronization devices:

·        CRT-pacemaker (CRT-P)

·        CRT-defibrillator (CRT-D)

A cardiac resynchronization therapy pacing (CRT-P) system utilizes conventional pacing technology, but takes it one step further by adding a third lead, or electrode, to sense and pace the left ventricle.

The pacing device can then simultaneously stimulate both ventricles in synchrony with atrial activity. The synchronous contraction of both ventricles facilitates more adequate filling of the left ventricle and less backflow to the left atrium, resulting in more oxygenated blood being pumped to the body.

Cardiac resynchronization therapy has also been incorporated into automatic internal cardioverter-defibrillator devices (CRT-D), allowing for the simultaneous treatment of congestive heart failure with intraventricular conduction delays and the prevention of sudden cardiac death caused by life-threatening ventricular arrhythmias.

In physician’s operative notes, you may see CRT devices referred to as one of the following:

CRT-P

·        Cardiac resynchronization therapy pacemaker
·        Biventricular pacemaker
·        Bi-V pacemaker
·        Low power CRT
·        Heart failure pacemaker

CRT-D

·        Cardiac resynchronization therapy defibrillator
·        Biventricular ICD
·        Biventricular pacemaker with defibrillator
·        Biventricular pacing with defibrillation
·        High power CRT
·        Heart failure pacemaker with defibrillator
·        Heart failure pacemaker with ICD

Outpatient Reimbursement



Hospital Outpatient Coding and Reimbursement Process


Similar to physicians, hospitals use ICD-9-CM codes for diagnoses and CPT or HCPCS II codes for procedures for outpatient encounters. For Medicare, hospital outpatient reimbursement is under the Ambulatory Payment Classification (APC) system.

Each CPT and HCPCS II code is assigned to an APC group with a unique relative weight, which is then converted into the payment amount. Unlike DRGs, multiple APCs can be assigned and paid for each outpatient encounter, depending on the procedure performed. Additional amounts may also be available for specific pass-through devices.

Medicare has used APCs for hospital outpatient reimbursement since 2000.

Changes to APCs and CPT procedure codes are effective January 1st

Inpatient Reimbursement




Hospital Inpatient Coding and Reimbursement Process


Hospitals assign ICD-9-CM codes for both diagnoses and procedures for inpatient admissions. For Medicare, inpatient hospital reimbursement is under the Diagnosis Related Group (DRG) system.

For each admission, the ICD-9-CM diagnosis and procedure codes are grouped into one of more than 800 DRGs. Regardless of the number of codes, only one DRG is assigned per admission. Each DRG has a unique relative weight, which is then converted into the payment amount.

Medicare has used DRGs for hospital inpatient reimbursement since 1983.

Changes to ICD-9-CM procedure and diagnosis codes as well as DRGs are effective October 1st of each year.

POA Documents



            Documents to capture POA Indicators in Inpatient reports/charts
         

Coders can use several documents to decipher POA information:

1.      ED notes: ED notes may state the patient’s condition in the workup.

2.      History and physical (H&P): A patient’s condition may be diagnosed or found in the workup of the H&P portion of the physician exam notes. Past medical history, as well as current medications, may be found here as well.

3.      Progress notes: Progress notes are a follow-up on a patient’s initial condition diagnosis. These notes may also reveal new fi ndings of existing conditions.

4.      Consults: Reports from a consulting physician may yield information for management of other conditions that need surgery.

5.      Admission forms: A nursing admission, an operating room admission, or an anesthesia workup may contain useful POA information.

6.      Laboratory and x-ray reports: Coders can look for information in the workup of both laboratory and  x-ray reports.

Coders should remember that admission forms, lab reports, and x-ray reports don’t support a POA indicator. To assign POA, coders must rely on a treating physician’s documentation.

Assuming physician documentation is accurate and complete, a coder can consider these tips when assigning the POA indicator:

·        Look in the history and physical, as well as the emergency room physician documentation and admitting progress note and orders. The cut-off point in determining whether the condition was POA, is when the admit order was written.

·        Look for confi rming diagnoses. Perhaps the physician documented a sign or symptom on admission, but didn’t render a diagnosis until two or three days later. The physician may have documented a diagnosis as “possible” or “probable,” but didn’t confi rm it until later in the progress notes. Only code a diagnosis listed as “possible” or “probable” if the condition is later confi rmed or still qualifi ed as uncertain at the time of discharge. Since the diagnosis is based on signs or symptoms that were POA, the coder would assign a “yes” indicator. Note that an uncertain diagnosis would be POA only when that diagnosis had related signs or symptoms that were present at the time of admission. Otherwise, if the signs and symptoms developed after the physician order, the diagnosis is not POA.
