One reason for inflated medical costs in the US. Abuse of CPT codes. Read on and save a bunch.

This article is specific to the US.

Summary: Over charging is very common by doctors and hospitals. Almost 80% of the bills are over charged. Pay attention to time spent with doctor, tests ordered and services performed. Check against the bill.
CPT (Current Procedural Terminology) codes.

Details:

In the US, we have many reasons for medical costs and therefore insurance to go up lot more than inflation.

Most people know the few reasons:

Frivolous mal-practice lawsuits people and ambulance chasing lawyers which can cause mal-practice insurance to be as much as 30% of an individual physician. It alone contributes to about 2.5% of the US medical cost.

Supply of doctors is artificially kept low by American Medical Association's control over the number of graduates per year. Very self-serving.

Price gouging by drug and equipment makers and hospitals charging 100 times the cost of medication like Tyelenol they give inpatients for example.

So called non-profit hospitals where the profits are pretty much divided as salaries and bonuses to the administrators and top brass to show no profit.

An insurance company provided the following breakup.

Let us take the above graphic for granted for now. Just note than 50% of the cost is hospitals and physicians. Why is that?

Here is what Aetna Insurance said in 2010.


Per Aetna:

Mergers of hospitals were followed by 20% price increase due to monopoly.

About half the spending increase per year is on Medical technology. Doctors are therefore encouraged to order tests which use this equipment.

"The biggest area of excess is defensive medicine, including redundant, inappropriate or unnecessary tests and procedures. Other factors that contribute to wasteful spending include non-adherence to medical advice and prescriptions, alcohol abuse, smoking and obesity."

So, what we can do as consumers of medical care? Do not assume that just because we have medical insurance paid for by the employer, it is cheap to go to doctor or emergency room. Do what we can to stay fit and eat healthy but go get the physical exam and flu shots as a minimum. When we do go to the doctor, have a family member or a friend to take notes of how much time was spent by your doctor with you and what procedures and services were performed. When you get the bill pay attention to CPT codes in the statement.

CPT codes are developed by the American Medical Association to identify codes most often used by physicians rendering services in the medical office. The most frequently used codes are medical Evaluation and Management (E/M) codes.
  1. 99201-05: New Patient Office Visit
  2. 99211-15: Established Patient Office Visit
  3. 99221-23: Initial Hospital Care for New or Established Patient
  4. 99231-23: Subsequent Hospital Care
  5. 99281-85: Emergency Department Visits
  6. 99241-45: Office Consultations
Most of what we need is 99213 a 15 min visit with established patient.

Office or other outpatient visit for the evaluation and management of an established patient, which requires at least 2 of these 3 key components: An expanded problem focused history; An expanded problem focused examination; Medical decision making of low complexity. Counseling and coordination of care with other physicians, other qualified health care professionals, or agencies are provided consistent with the nature of the problem(s) and the patient's and/or family's needs. Usually, the presenting problem(s) are of low to moderate severity. Typically, 15 minutes are spent face-to-face with the patient and/or family.

You can plug in the code and see what it means here.

Doctors think that 61% of the time they are using 99213 wrongly instead of 99214 for 30min.

I beg to differ. Most of the time we go to the doc office for a 30min appointment, we are waiting in the exam room for 10min, nurse 5 min before 5 min after doctor and perhaps 10min with the doctor. It should be 99212 most of the time.

Then pay attention to the tests ordered and other services which can inflate the bill. Insurance companies cannot challenge it. Only consumers can.

Interesting failure with SmartThings coincided with Hub v2 and App update. Android App 2.0.3 brought back Hello Home under Routines.

If you browse my blogs you will see very glowing articles about SmartThings.

You need to know the not so good too.

Summary:
One of the GE Z-wave dimmer switches (made by Jasco) stopped responding to the SmartThings Hub to turn ON and OFF. I eventually got it to work without help from support. I called it Entry Light.

Solution was to remove the switch forcibly using the Android App, remove the bulb, screw the same bulb into the same socket, add new device and call it Entry Light. When I removed the device, I had to remove it from 2 Apps which were controlling this switch. One of the Apps was Smart App called Hello Home from Smartthings.

I luckily had one Android phone rinning version 1.7.6 of the App which still has Hello Home and all the things I automated.

Interesting thing is after the Android App update to newer App version 2.02 and the Hub update the App Hello Home was replaced by something else Market Place -> SmartThings Recommends -> Smart Lights -> Automations. I was able to add a new App to shut off the light called Entry Light.

However, the old Hello Home App still runs on the devices it was supposed to. Now if I want to add back the Z-Wave switch which I was forced to remove and add back, I cannot even see the App. Unbelievable!

I also had a SmartApp called Clothes Dryer stopped. I still use it to detect end of cycle by sensing vibration on washer and dryer and they work. It is an App called Laundry Monitor which was moved into a new section. Market Place -> More -> Laundry Monitor. They could have moved Hello Home also under More.

That App Laundry Monitor is the only one listed under My Apps. Hello Home disappeared but still the App works and I cannot modify and device or the features. I am in touch with support about this strange problem. I will update it when I am done. BTW, it took me 5 days to get a response from support but one day after I posted on Twitter. Apparently they are busy with the v2 Hub. BTW, migrating to the new v2 hub requires all the devices and Smart Apps to be deleted and re-installed.

What they say about the new hub v2 is
" SmartThings Hub will come equipped with “AppEngine” functionality. This means that much of the processing that has previously existed in the cloud (ie: SmartApps and device types) can now automatically occur locally in the Hub. Circumventing the cloud will result in a much faster response time with automations. It will also mean that certain automations (SmartApps; Hello, Home actions, etc.) driven by ZigBee, Z-Wave, or LAN-connected devices will continue to work even if you lose your Internet connection. And because the new Hub contains battery backup capability, certain automations can continue to work for awhile even without power."

Well for the Smart App called Hello to work you first have to find it...
I think it was the missing Menu in the Android 2.0.2 update all they had to do was put it back under routine for existing users. Looks like this was fixed in 2.0.3. I was asked to look under Routines and there they were.



I was told that there would be a migration process for upgrading from hub v1 from hub v2 by the end of this year. I look forward to it. Compared other IoT hubs, I surely recommend new users to try the new v2 hub by SmartThings and look forward to an easy upgrade for existing hub v1 users so that all the devices will disconnect from the hub, the new hub connects to servers and then connects to all the devices using the device ID.

How I was cheated in India.


Rented a Toyota corolla in Hyderabad for 8hrs. He was actually there for 6hrs. Yet demanded 20% more than he orally quoted for 8hrs.

Rented a Toyota corolla for 4 hrs. He dropped us in a place and said that he needs to return a ledger to his office and will come back in 30min. He came 90 min later and made us wait for 30min. We went to 2 other places. In the 3rd place he said he needs petrol and was gone for 1hr. He asked us to pay for the entire 4hrs. I have a feeling that he made money on the side.

Wanted to recharge airtel phone at a local place my in-laws knew in Madras. We paid money upfront. He said 15 min. After 20 min, we said that we will do little shopping and come back in 30 min. After we went back in 30 min and waited 15 more min, we asked for money back. He made us wait for another 15 min to give money back. Went directly to Airtel retail location and got recharged in 5 minutes. No idea what this guy was doing. May be he gets a cut and so he is a lower priority for Airtel.

Wanted to get DSL service from Airtel in Hyderabad. The guy asked if I want wireless and asked about $40 equivalent for a DSL wireless router which he said I would own. It did not work. They did not take back the router. I had no real service, wasted several hours of my time. I was stuck with the router and I was forced to pay for 10 days of service I did not get plus I was stuck with a useless DSL modem.

My cousin wanted my help to invest in Indian stock market. A citi bank guy approached him and I was there. He was pitching very high risk mutual funds for a 2% fee on an investment of 200,000 which was Rs. 4000. We decided to open account at ICICI brokerage. The commission per trade was about Rs. 50. We did not plan to do more than 1 trade per week. When we bought NIFTY ETF, I noticed that the volume of trading was low because the difference between ask and bid was lot more. For example if ask was 100, bid was 101 1%. When we bought we had to pay 101. 2 weeks later, we saw ask was 101 and bid was 102. Since we are selling we bid 102. Not sold. After a while we had to sell at market price. What we got was 99. So, instead of gaining 1% in 2 weeks, we lost 1%. That means brokers made money. We closed the account and opened an account in the US. It did just fine. In the US, if the ask in 100, bid would be 100.02 and market price may be 100.01. Huge difference.

Summary:

Big difference in what is promised and what is delivered. Clearly, they do not care about customer satisfaction. Goal is to say anything to get your money.

Interesting experience with Automatic car driving assistant 2 cars 2 phones.

Automatic

It attaches to OBD2 port in the car and for now only gives MPG per trip and has apps for expense reports where you need to submit logs. For a non business user, it might make you a better driver by warning you on hard acceleration, hard braking or going above certain speed limit you get to set which is really on the highway. It connected with my phone using my email account, phone number and bluetooth and connected with my wife's email account, phone number and bluetooth. When both were in the car, I never really checked if both recorded the same but when I was driving either car, I surely saw the record.

I was an early adapter and got the first gen unit in 2 cars and both my sons also got it for their cars.

First of all I do understand that a bluetooth slave can be paired only with one bluetooth master. So, it is reasonable that if there are 2 phones in the same car with Automatic, only one of them will actually connect with Automatic first and both phones will not see real time status such as Driving. I know that Automatic suggests that the passenger to disable bluetooth so that the driver's phone will link with the Automatic and later on the passenger can enable bluetooth later. That is rather inconvenient. As a minimum, allow a setting to indicate primary phone for each car at the time of set up. If both phones are present, the primary will connect.

However, I suggest an enhancement. Currently, each smart phone which pairs with the Automatic is required (suggested) to ave its own email account and password on Automatic's Server. I suggest a notion of family account that email accounts and passwords can be entered on the Automatic's server to "link" the multiple phones to the same account. When the car is moving allow the option of sending location to the server periodically and rather that say "driving", show speed on the map and show status "stopped" or "parked" based on the status of the engine. Also good to see other status in real time such as engine temperature, distance and avg mpg since last filled (Allow user to mark when tank was filled). Make remote tracking an optional feature with parental lock when a car is given to a new driver by a parent. Finally, after the trip was completed, allow linked accounts to see the complete status and history.

I used IFTTT on both email accounts to send email to a single address at the end of the trip. I also have the option of appending data to a shared .csv file in Dropbox of Google Drive using IFTTT. Automatic could allow sharing too and make it a social networking experience as well.

Once more suggestion I have for Automatic is to change the App to ask if there is another car nearby with Automatic installed in it or scan and inform the user to move away from the other one before set up of a new automatic. Lot of my issues would have gone away.

Finally, I would like to acknowledge the support I received for Craig Drake and Derrick S of Automatic. Together they helped me pair a Samsung Galaxy Note 2 running Kitkat and a Samsung Galaxy Note 3 running Lollipop to a gen 1 automatic and a gen 2 automatic in 2 cars which are parked in the same garage.
It took 2 weeks but bottom line is I got credit for a defective unit and the new one is working.
