AAPC CPC Chapter 7 Integumentary System 2023/2024 updated to pass

AAPC CPC Chapter 7 Integumentary SystemWhat term relates to connection of skin to underlying muscles? - correct answer Correct Answer:b. Hypodermis Response Feedback: Rationale: The hypodermis is also known as subcutaneous tissue and is made up of fat and connective tissue responsible for binding skin to the tissue beneath it. A patient is taken to surgery for removal of a squamous cell carcinoma of the right thigh. What is the correct diagnosis code for today's procedure? - correct answer Correct Answer: C44.722 Response Feedback: Rationale: In the ICD-10-CM Alphabetic Index look for Carcinoma, there is a note to see also Neoplasm by site, malignant. Go to the Table of Neoplasms and look for Neoplasm, neoplastic/skin NOS/limb NEC/lower/squamous cell carcinoma/Malignant Primary column refers you to subcategory code C44.72-. In the Tabular List the 6 th character 2 indicates the right lower limb (thigh). What is commonly known as a boil of the skin? - correct answer Correct Answer: Furuncle Response Feedback: Rationale: Carbuncles and furuncles (boils) typically are caused by a staphylococcal infection. Several furuncles together make up a carbuncle and often involve a group of hair follicles. Melanin is found in what layer of the epidermis? - correct answer Correct Answer: Basal Response Feedback: Rationale: Scattered throughout the basal layer of the epidermis are cells called melanocytes, which produce the pigment melanin, one of the main contributors to skin color. What is the correct diagnosis code to report initial treatment of an infected post procedural stitch abscess of the right leg from a previous excision of a squamous cell carcinoma? - correct answer Correct Answer: T81.41XA Response Feedback: Rationale: In the ICD-10-CM Alphabetic Index look for Abscess/stitch or Complication/surgical procedure/stitch abscess or Stitch/abscess referring you to T81.41-. In the Tabular List, seven characters are needed to complete the code. The 5th character identifies the depth of infection. Since the infection is a stitch abscess, 1 is the correct 5th character. One X placeholder is for the 6th character and the 7th character A is reported for initial encounter (or treatment). An instructional note indicates to use an additional code to identify the infection. We do not know what the type of infection, so it is not coded. What CPT® code(s) would best describe treatment of 9 plantar warts removed and 6 flat warts all destroyed with cryosurgery during the same office visit? - correct answer Correct Answer: 17004, 17110 Response Feedback: Rationale: Cryosurgery is a method of destruction using extreme cold to destroy the lesion. The method selected for destroying benign or premalignant lesions is based on the type of lesion and number of lesions. There were 16 premalignant lesions destroyed. Look in the CPT® Index for Destruction/Lesion/Skin/Premalignant and you are directed to codes 17000-17004, 96567. In the numeric section, code 17004 is the only code reported for this procedure because 16 lesions were destroyed. There is a parenthetical note under code 17004 that states "Do not report 17004 in conjunction with ." Ten benign lesions were destroyed. In the CPT® Index look for Destruction/Lesion/Skin/Benign and you are referred to codes 17110 and 17111. Code 17110 is reported for destruction of 10 lesions. What CPT® codes are reported for the destruction of 16 premalignant lesions and 10 benign lesions using cryosurgery? - correct answer Correct Answer: 12051, 11441-51, D22.39 Response Feedback: Rationale: This is excision of a benign lesion (nevus) of the face. In the CPT® Index look for Skin/Excision/Lesion/Benign and you are directed to code range . Code selection is based on location and size. The lesion is on the face, narrowing the code selection to . The lesion size is documented as 0.8 cm plus 0.2 cm for the margins (.1 cm on each side) for a complete excision of 1.0 cm of the face making 11441 the correct code. Category guidelines for Excision-Benign Lesions state if the repair is intermediate (layers), a code from range is reported in addition to the excision code. Code selection is again based on location and size. 12051 is the correct repair code.
