X D. . - answerX Rationale When doing diagnosis coding, an "X" is always used as a place holder. Some ICD-10-CM codes require 7th characters.

L89.133 - answerL89.143 Rationale In the ICD-10-CM Index, the main terms is Ulcer, pressure, stage 3, back, category L89.1. In the Tabular List, category L89.1, there are many choices for coding specific parts of the back and the stage of the ulcer, such as for this case, the left lower back, state 3. L89.133 is for the right lower back stage 3 (it is identified as left low back). L89.139 is for the right lower back unspecified stage (this is specified to stage 3). L89.141 left lower back stage 1 (not the correct stage). L89.143 left lower back, stage 3, this is the correct code for a pressure ulcer of this stage and location. 3. The patient is a 56-year-old male who presents to the office today to discuss the results of recent laboratory tests. Discussion with Patient: I discussed with the patient that he has diabetes mellitus. Patient educational information was given and he was referred to the Diabetic Clinic to attend educational classes. He was given information about the need to maintain a well-balanced, nutritious diet. His diabetes will be managed by diet therapy. He is to schedule an appointment and to return to my office in four weeks. Assessment: type 2 diabetes. Which of the following is the correct ICD-10-CM code assignment? A. E10.9 B. E11.9 C. E10.59 D. E11.59 - answerE11.9 Rationale In the ICD-10 index, the main term is "Diabetes Mellitus". Under "Diabetes Mellitus", find "Type 2". This search will lead to code E11.9. This is correct because there is no further specification for the diabetes. Type 2 is the default Diabetes Mellitus code when the type has not been specified. 4. When a patient has a blood test done for HIV and the results are inconclusive, which of the following ICD-10-CM codes should be assigned? A. B20 B. R75 C. Z21 D. Z11.59 - answerR75 Rationale B20 is a code that states the patient has been diagnosed with HIV. (Do not use this code unless there is a definite diagnosis of HIV). R75 is the code used for inconclusive results for the HIV condition, and is the correct code to use. Z21 is used for a patient who is asymptomatic (positive for the virus but is not showing any symptoms to date), Z11.59 is for screening for the condition. 5. A patient reports to the physician office with complaints of swelling and ankle pain. After x- ray and examination the physician listed the final diagnosis as effusion of the right ankle joint. Which of the following ICD-10-CM should be assigned? A. M25.471 B. M25.474 C. M25.48 D. M25.571 - answerM25.471 Rationale The patient's complaints of swelling and ankle pain are signs and symptoms of the condition. The physician has documented the definitive diagnosis as effusion of the right ankle. In the ICD- 10-CM Alphabetic Index, the main terms are Effusion, joint, ankle, code M25.471. Checking the Tabular List for code M25.471, it identifies effusion of the right ankle so ICD-10-CM code M25.471 is the correct code. M25.474 identifies the right foot; M25.571 identifies pain in the right ankle and foot. (The symptom of joint effusion is not coded since there is a definitive diagnosis,) M25.48 identifies effusion of other site. (This clearly states the right ankle so this is not the code needed). 6.
