Billing CPT 99234, 99235, 99236 with example

here are 3 codes for Observation admission and discharge of a patient in the same day. these are 99234, 99235 and 99236.

The inpatient and outpatient E and M codes all have the same format. New Patient? You must meet all 3 criteria. In this case it all admitted patients are considered new patients in house....

So these criteria are very similar to outpatient encounters.

The 99236 requires:

1. Comprehensive history
2. Comprehensive Examination
3. Medical decision Making of High Complexity

The Comprehensive history is:
1. A chief complaint
2. An extended HPI (four HPI elements OR the status of three chronic or inactive probs.
3. A 10 system ROS
4. A Complete PFSH. Which includes Meds, Allergies, FamHx, SrgHx, MedHx
Remember it only takes on element from each category of the PFSH to qualify as complete.

The Comprehensive Examination is 2 points from 9 organ systems

Lastly for all admitted patients you must ALSO meet the third criteria.....Medical Decision Making.....

MDM for short. In this case 99236 the medical decision making must be of high complexity. Which is ALWAYS a bear, unless you know how to do it.

MDM is judged by 3 criteria.

  • Problem Points, 4 points required
  • Data Points, 4 Points Requires
  • Risk Chart, High Risk
Luckily, you only need 2 of 3 criteria to qualify for the Highest Level of MDM. Most people accomplish this feat through data and problem points....

Always hit the problem and the data points, Strive to hit risk….

You need Four Problem Points

New Problem with work up (4)
New problem no Work up (3)
Est Problem, Worsening (2)
Est Problem Stable(1)

Four Data Points
Labs(1) Ordered OR Reviewed
Indep Review of EKG/Film/Specimen (2)
Reviewed Old records (2)
Decision to Obtain Old Records (1)
Discuss test with Physician(1)
Order Test EKG/Cath/PFTs (1)

Risk, to be high risk
1 New Problem which poses a threat to life or limb
1 chronic illness with severe exacerbation
1 change in neurologic status

Or if you chose to do

1. Cardiovascular imaging, with contrast
2. Cardiac EP studies
3. Diagnostic endoscopies
4. Discography
5. Elective major surgery
6. Emergency major surgery
7. Parenteral controlled substances
8. Drug therapy requiring intensive monitoring for toxicity (Digoxin/Heparin)
9. Decision not to resuscitate, or to de-escalate care because of poor prognosis
Or the decision to do the following

Most of these things aren't done on an ambulatory basis, so you are essentially screwed with the risk part of this.

In other words, YOU CAN ONLY BILL 99236 IFF you meet the Problem AND Data points. IF you do not, you cannot likely make the grade for a 99236.

Hospital Observation Services During Global Surgical Period

The global surgical fee includes payment for hospital observation (codes 99217, 99218, 99219,99220, 99224, 99225, 99226, 99234, 99235, and 99236) services unless the criteria for use of CPT modifiers “-24,” “-25,” or “-57” are met. Contractors must pay for these services in addition to the global surgical fee only if both of the following requirements are met:

• The hospital observation service meets the criteria needed to justify billing it with CPT modifiers “-24,” “-25,” or “-57” (decision for major surgery); and

• The hospital observation service furnished by the surgeon meets all of the criteria for the hospital observation code billed.

Examples of the decision for surgery during a hospital observation period are:

• An emergency department physician orders hospital outpatient observation services for a patient with a head injury. A neurosurgeon is called in to evaluate the need for surgery while the patient is receiving observation services and decides that the patient requires surgery. The surgeon would bill a new or established office or other outpatient visit code as appropriate with the “-57” modifier to indicate that the decision for surgery was made during the evaluation. The surgeon must bill the office or other outpatient visit code because the patient receiving hospital outpatient observation services is not an inpatient of the hospital. Only the physician who ordered hospital outpatient observation services may bill for observation care.

• A neurosurgeon orders hospital outpatient observation services for a patient with a head injury. During the observation period, the surgeon makes the decision for surgery. The surgeon would bill the appropriate level of hospital observation code with the “-57” modifier to indicate that the decision for surgery was made while the surgeon was providing hospital observation care.

Examples of hospital observation services during the postoperative period of a surgery are: A surgeon orders hospital outpatient observation services for a patient with abdominal pain from a kidney stone on the 80th day following a TURP (performed by that surgeon). The surgeon decides that the patient does not require surgery. The surgeon would bill the observation code with CPT modifier “-24” and documentation to support that the observation services are unrelated to the surgery.

• A surgeon orders hospital outpatient observation services for a patient with abdominal pain on the 80th day following a TURP (performed by that surgeon). While the patient is receiving hospital outpatient observation services, the surgeon decides that the patient requires kidney surgery. The surgeon would bill the observation code with HCPCS modifier “-57” to indicate that the decision for surgery was made while the patient was receiving hospital outpatient observation services. The subsequent surgical procedure would be reported with modifier “-79.”

• A surgeon orders hospital outpatient observation services for a patient with abdominal pain on the 20th day following a resection of the colon (performed by that surgeon). The surgeon determines that the patient requires no further colon surgery and discharges the patient. The surgeon may not bill for the observation services furnished during the global period because they were related to the previous surgery.

An example of a billable hospital observation service on the same day as a procedure is when a physician repairs a laceration of the scalp in the emergency department for a patient with a head injury and then subsequently orders hospital outpatient observation services for that patient. The physician would bill the observation code with a CPT modifier 25 and the procedure code.
