Clinical Classification Systems

1.	A patient presents with CKD stage III, edema and hypertension. The correct ICD-10 CM codes for this chart are:
		a. N18.3, I10, R60.9
		b. N18.9, I10, R60.9
		c. N18.3, I12.9
		d. N18.9, I12.9, R60.9
Per ICD-10CM guidelines do not code signs and symptoms. Edema is a symptom of both hypertension and CKD. ICD-10CM guidelines state there is a casual relationship assumed between CKD and hypertension unless the provider specifically states that the hypertension is not related to the CKD, giving this patient hypertensive chronic kidney disease instead of regular hypertension. Incorrect answer. Please choose another answer.

2.	A 42-year-old female, who is a new patient, presents with foul-smelling urine, frequency, flank pain and fever for 4 days. Patient denies nausea and headache. Patient is not sexually active and is a non-smoker. The provider performs the following exam in addition to patient's height, weight and blood pressure check: General: Well-developed, well nourished, in no acute distress Ears: external ears normal, TM bilaterally intact Neck: Supple, no thyromegaly Extremities: No edema Cardiovascular: RRR, no bruits Lungs: Clear to auscultation The patient is prescribed ciprofloxacin and given a diagnosis of acute cystitis without hematuria. The correct coding for this encounter, using 1997 E/M guidelines is:
		a. 99202, N30.00
		b. 99203, N30.00, R30.0
		c. 99202, N39.0
		d. 99203, N39.0, R30.0
1997 E/M guidelines state that the provider must reach 12 bullet points for a detailed level of exam. Although the patient's chart has a detailed history and moderate medical decision making, the provider only reached 11 bullet points, making this level a 99202. N39.0 is not the most specific code for this chart. Incorrect answer. Please choose another answer.

3.	A patient presents with a cyst at the base of his tailbone. It is swollen and painful for the patient to sit down. The provider drapes the patient in the usual fashion, administers lidocaine and uses a scalpel to excise the 2cm cyst and a subcutaneous extension, rinses it with sterile saline, performs an intermediate repair of the wound with a layered closure. The correct CPT code assignment for this procedure is:
		a. 10080, 12001-59
		b. 10081
		c. 11771
		d. 11770, 12031-59
The provider performs an excision, not an incision, completely removing the cyst. The excision is intermediate because it involves subcutaneous extensions and the repair is included with the procedure. Incorrect answer. Please choose another answer.

4.	A 7-year-old child presents for a series of vaccines. The patient receives MMR and DTaP and counseling on vaccines. The correct CPT code assignment for this procedure is:
		a. 90460, 90461
		b. 90471, 90472
		c. 90460, 90461x5
		d. 90460x2, 90461x4
Pediatric vaccines with counseling are coded per component. Each first component of a vaccine (Measles and Diphtheria in this case) are coded as one unit of 90460. Each additional component to the vaccine (mumps, rubella, tetanus and acellular pertussis) receive another 90461 for an additional component code. Incorrect answer. Please choose another answer.

5.	ICD-10 codes are used:
		a. as procedure codes
		b. in DRGs
		c. as diagnosis codes
		d. All of the above
ICD-10 PCS are used as procedure codes for inpatient visits. DRGs use similar ICD-10CM weights for facility reimbursement and ICD-10CM are used as diagnosis codes for all healthcare settings. Incorrect answer. Please choose another answer.

6.	For urosepsis, a coder must:
		a. Use the code for severe sepsis
		b. Use the code for sepsis with organ dysfunction
		c. Query the provider
		d. Code first localized sepsis
According to ICD-10CM guidelines, urosepsis is a nonspecific term and has no tabular position. The provider must be queried for clarification. Incorrect answer. Please choose another answer.

7.	A patient comes into the office with white fuzzy patches on their tongue and is diagnosed with oral hairy leukoplakia. The provider runs a test for HIV and notates that the patient has HIV in the chart, but does not have a positive lab test yet. The patient is a smoker. What is the correct sequencing of these ICD-10 codes?
		a. B20, K13.3, F17.200
		b. K13.3, R75, Z87.891
		c. B20, K13.3, Z87.891
		d. K13.3, Z21, F17.200
According to chapter guidelines, if a patient is seen for an HIV-related condition, (which oral hairy leukoplakia is), then B20 is coded first, then the complications. Only the provider's statement is needed that the patient has HIV, not a positive lab test. F17.200 is to be assigned when the provider documents "smoker", but gives no further clarification (AHA: 2016, 1Q, 36) Incorrect answer. Please choose another answer.

8.	A 25-year-old patient is 27 weeks and 6 days pregnant. The patient is experiencing dysuria and blood in her urine. She is diagnosed with acute cystitis. What is the correct coding of this patient's chart?
		a. N30.01, Z33.1
		b. O23.32, N39.0, Z3A.27
		c. O23.12, N30.01, Z3A.27
		d. N30.00, Z33.1
Cystitis is an infection of the bladder. The provider must specifically state that the infection or condition is not affecting the pregnancy for an incidental code. The patient is experiencing blood in her urine, which gives us the hematuria portion of the diagnosis. Incorrect answer. Please choose another answer.

9.	A patient comes in after her pressure cooker has exploded and covered her face with boiling soup. She was luckily wearing a sweater which protected her arms. She has partial-thickness burns covering her entire face.

		a. 01730 P1
		b. 01742 P1, 99100
		c. 01744 P1
		d. 01756 P1, 99100
Anesthesia for all closed procedures on humerus and elbow. The 99100 code is only used for patients under 1 year old or over 70 years old. 01744 is for open procedures, not closed. Incorrect answer. Please choose another answer.

Confidentiality and Privacy

11.	The Breach Notification Rule, found in the ______ Rule of HIPAA, states that when _____ individuals have had their confidential data exposed and the covered entity has outdated contact information for them, that the covered entity must_____ for ______ days.

		d. Privacy Rule, 5 or more individuals, post a notice on their website, in the lobby and send postcards with information at least 3 times over 90 days.
The Omnibus Rule established HITECH and the AARA of 2009 and finalized the Breach Notification Rule, mandating that covered entities who have more than 10 individuals with outdated contact information involved in a data breach must be notified by posting a notice on their website or creating a local ad in the newspaper. For breaches over 500 individuals, major news outlets must be contacted and the Secretary of HHS immediately. Incorrect answer. Please choose another answer.

12.	Sally calls the coding department to contest the duplicate procedures that her adult sister received while admitted to an inpatient mental health facility. Sally has her sister's date of birth, her name but not her ID number. She says her sister is too depressed to advocate for herself and Sally just wants the charges reviewed. What do you do?
		a. Tell Sally you'll review her sister's chart while she was hospitalized and process a corrected claim if needed.

Incorrect answer. Please choose another answer.

13.	You need a second opinion on coding a chart from your Coding Manager, who does not have access to the patient's records. You decide to e-mail a screenshot of the chart to the Coding Manager. What steps must you take to ensure that the patient's data is protected in your email?
		a. Create a confidentiality notice in your email, asking an unintended recipient to delete the information
		b. Follow all company guidelines to encrypt your email
		c. Remove patient's name, date of birth, insurance ID#, SSN, address and patient number before emailing
		d. All of the above
HIPAA HITECH requires that covered entities take reasonable action to protect electronically transmitted information. Removing protected health information, encrypting email and creating confidentiality notices are a multi-layered security approach that is best-practice to prevent breaches of data. Incorrect answer. Please choose another answer.

Reimbursement Methodologies

14.	Facility payments are based on:
		a. Fee schedules
		b. ICD-10 PCS codes
		c. IPPS using DRGs
		d. RVUs and conversion factors
The Inpatient Prospective Payment System drives value-based care by paying inpatient stays based on DRGs (Diagnosis-Related Group(s)) which are groups of diagnoses with similar weights in order to determine "how much" a patient's stay ought to cost. These drivers force hospitals to work to be most efficient in their use of resources to come in under what they will be paid in order to avoid losing money. Incorrect answer.

15.	Conversion factors:
		a. Are based on how difficult a procedure is
		b. Depend on the level of education a provider has
		c. Are based on locality
		d. None of the above
RVUs are based off work for each HCPCS. RVUs are multiplied by Geographic Practice Cost Indices (GPCI), which account for physician work, cost of malpractice and practice expenses. A conversion factor, which is a national number that changes annually, is multiplied by the sum of RVUs that are multiplied by the GPCI to calculate payment for professional fee schedules. Incorrect answer. Please choose another answer.

16.	Pressure ulcers, catheter-associated urinary tract infections, falls and head trauma, DVTs and pulmonary embolisms are all examples of:
		a. DRGs that should have a POA indicator
		b. Hospital-acquired conditions that will not be reimbursed
		c. Part of similar weight DRGs
		d. Complications that must be coded to receive full reimbursement
The HAC-POA (Hospital acquired condition, present on admission) program was created by the Deficit Reduction Act of 2005--any of these conditions which are not present on admission and could have reasonably been prevented by following accepted standards of care will not be reimbursed. Usually, adding the DRG weight would have increased the facility's reimbursement, but this forces hospitals to avoid hospital acquired conditions, rather than profit from them. Incorrect answer. Please choose another answer.

17.	Relative Value Units are:
		a. Different for each locality
		b. A weight for procedure codes
		c. Multiplied with conversion factors

Compliance

28.	You work at a billing company, coding charts for clients. Your manager sends out claims that have not been coded professionally because your team is 2 months behind and out of compliance with your service line agreement in the contract with your client, but says that it is okay because the provider has coded the claims at the time of service and the client does not want to pay for extra coding. Which of the following statements is true?
		a. This is fine because the provider coded the claim to the best of their ability and therefore cannot be held liable.
		b. Billing companies have liability for fraudulent claims that they submit, including undercoding, so this is not acceptable.
		c. Only overcoding is fraudulent, so this is acceptable.
		d. The providers mostly under-code their services, so it's really saving the insurance money and saving us work!
The OIG states that billing companies who submit fraudulent claims (as well as the person who submitted them!) are just as responsible as the provider who rendered the services. Both undercoding and overcoding are examples of fraudulent claims, the claim submitted must accurately represent the services rendered. Incorrect answer. Please choose another answer.

29.	Which of the following are considered fraudulent:
		a. Use of modifier -59 to report a distinct and separate service that would otherwise be prohibited by NCCI guidelines.
		b. Changing the code on a claim because the provider did not meet documentation standards.
		c. Use of modifier -25 on a minor evaluation and management service that is coded with a related procedure.
		d. All of the above are acceptable practices.
Procedures include a minor evaluation and management service. If the patient complains of an abscess and a I&D is performed, only the procedure should be reported. If the patient comes in complaining of hypertension and an abscess is discovered, then it would be acceptable to report an evaluation and management service. Incorrect answer. Please choose another answer.

30.	Which of the following is an example of a compliant query to a physician:
		a. 06/30: Dr. Brown, can you add documentation for the procedure you did on for Mrs. Parks 5/22? We've billed it out but I'm worried that there isn't enough documentation to support it. We know you did the procedure, but just need a little something extra!
		b. 6/30: Dr. Brown, can you clarify in the patient's chart Mrs. Cramb's diagnosis for 6/27 given the positive rapid strep test that was uploaded?
		c. 6/30 Dr. Pepper, can you add acute sinusitis (if that's what he had!) to Mr. Meltzer's record--all we have is nasal congestion, headache and malaise and I see you prescribed him antibiotics. Thanks!
		d. 6/30 Dr. Pepper, I see that you gave Mr. Evans a diagnosis of unspecified loss of kidney function, but we would get paid a bit more if it were Chronic Kidney Disease, would that be an appropriate diagnosis to code for this patient?
Physician queries must be non-leading, not based on reimbursement, for the purpose of improving patient care and open-ended, or Yes/No questions. Providers must not add documentation solely for the purpose of being reimbursed and it must be within a reasonable time frame. Incorrect answer. Please choose another answer.
