Add-on code 11045 for additional subcutaneous surface area

For Mohs micrographic surgery, CPT® coding is based on the anatomic location of the lesion, the number of stages, and the number of tissue blocks per stage.

17311: This code is used for Mohs surgery on body areas such as the trunk, arms, or legs for the first stage.

17315: This is an add-on code used when more than five tissue blocks are examined in a single stage. Since this case involved six tissue blocks, 17315 is appropriate.

Explanation of incorrect answers:

A. 17313, 17314, 17315: Incorrect, as 17313 applies to the head, neck, hands, feet, or genitalia, not the arm.

C. 17313, 17315: Incorrect, as 17313 is not appropriate for the arm.

D. 17311, 17312, 17315: 17312 is used for additional stages beyond the first, which is not applicable here since only one stage was performed.

E. 85B2-335 is not a valid CPT code for Mohs surgery.

Thus, the correct answer is B. 17311, 17315, which accurately reflects a single-stage Mohs surgery with six tissue blocks on the arm.

In CPT® fracture and dislocation care, manipulation refers to the application of force or traction to restore a bone or joint to its normal anatomic position.

This is a key distinction between with manipulation and without manipulation, which directly affects CPT code selection (e.g., 23505 vs. 23500).

Manipulation may be performed closed (no incision) or open (with incision).

99214 aligns with CPC exam standards

1. Procedure and CPT® Code Selection:

The emergency department physician placed an indwelling catheter into the lumbar region for continuous infusion for pain management with fluoroscopic guidance.

CPT® Code 62327 is appropriate for injection or catheter placement for continuous infusion of anesthetic or analgesic in the lumbar or sacral region using imaging guidance.

CPT® Code 77003 represents the fluoroscopic guidance used during the catheter placement, which is separately reportable in this case.

2. Rationale for Excluding Other Options:

Code 62326 (in options B and D) is for the injection or catheter placement without imaging guidance. Since fluoroscopic guidance was specifically mentioned, 62327 is the appropriate choice.

Code 77003 must be reported separately when fluoroscopy is used in conjunction with 62327 for pain management catheter placement.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, the combination of 62327 and 77003 is correct when catheter placement for continuous infusion is performed with fluoroscopic guidance.

Therefore, the correct answer is C. 62327, 77003.

The patient had a post-operative complication (cardiac tamponade) following a previous CABG surgery, requiring a return to the operating room for exploration and evacuation of a blood clot. This is coded using CPT code 32658 (Exploration, mediastinum, with or without drainage; for postoperative hemorrhage, drainage of abscess, or to locate foreign body). Modifier 78 is appended to indicate an unplanned return to the operating room by the same physician following the initial procedure for a related procedure during the postoperative period.

99152 – Moderate sedation, same physician, patient under 5 years, initial 15 minutes

Time documented: 21 minutes

First 15 minutes = 99152

Additional 15 minutes (99153) not reported separately in CPT® exam context

Why others are incorrect:

99151 – Minimal sedation

99155 / 99156 – Different age/provider scenarios

73522 = Bilateral hips with pelvis, 3–4 views

Modifier -76 = Repeat procedure by the same physician

Modifier -51 identifies multiple procedures

The injection into the trochanteric bursa under ultrasonic guidance is coded with CPT® 20611, which describes an injection of a major joint or bursa with ultrasound guidance. The modifier -LT indicates the procedure was performed on the left side.

11765 = Excision of nail fold (wedge excision), ingrown toenail

TA = Left great toe

Other codes are incorrect:

11730 = Partial nail avulsion

11750 = Nail excision

11755 = Biopsy

Correct answer: 11765-TA

30901 = Control of anterior epistaxis, limited, any method

30903/30905/30906 are for extensive packing or posterior epistaxis

82252 = Bilirubin, feces

82247/82248 = Serum bilirubin

82239 = Fecal fat

This scenario describes apalatoplasty(repair of cleft palate) withclosure of the alveolar ridgeusing abone graft. CPT code42210is the code that captures palatoplasty withclosure of the alveolar ridgeand associated bone grafting work as part of the reconstructive procedure described. Because the bone graft is part of the defined palatoplasty service in this code concept, you donotseparately report a generic bone graft harvesting code such as20900in the way the answer options suggest. The distractor42200is associated with a more limited palate repair (not matching the alveolar ridge closure with graft detail), and42205does not reflect the specific alveolar ridge closure with bone grafting described in the question stem. CPC exam strategy: identify the mostcomprehensive cleft palate repairthat matches the documentation; when a CPT code description includes the specific additional work (like alveolar ridge closure with graft), code that single comprehensive service.

1. Procedure and CPT® Code Selection:

The provider performed both a bronchoscopy and a microlaryngoscopy to evaluate the patient’s airway due to respiratory distress and stridor.

Code 31622 is used for a diagnostic bronchoscopy, which includes the inspection of the trachea, carina, and bronchial structures. Since the bronchoscopy was diagnostic and no additional therapeutic procedures were performed, this is the appropriate code.

Code 31526 is for direct laryngoscopy with the use of an operating microscope or telescope (microlaryngoscopy). This code is appropriate given the use of a Parson’s laryngoscope and magnifying telescope to inspect the larynx.

2. Modifier 51:

Modifier 51 is added to 31526 to indicate that it was performed in conjunction with another procedure (31622, bronchoscopy). Modifier 51 denotes multiple procedures without the necessity of a separate incision.

3. Exclusion of Code 69990:

Code 69990 is used for the use of an operating microscope in microsurgery but is not coded separately when the procedure (such as microlaryngoscopy) already includes visualization with a microscope or telescope as part of the CPT® descriptor. Thus, 69990 is not separately reported in this scenario, per CPT® guidelines.

4. AAPC and CPT® Coding Guidelines:

The guidelines specify that when visualization or microlaryngoscopy is inherently part of the procedure (as in 31526), 69990 should not be billed separately. Also, the use of Modifier 51 for multiple procedures in the same session is appropriate.

Therefore, the verified answer, following the CPT® and AAPC coding rules, is A. 31622, 31526-51.

Injection of atropine: Atropine is administered to reduce sialorrhea.

Bilateral submandibular salivary glands: The physician administers the injections into the salivary glands.

Total of four glands: Indicates that multiple glands are treated in the same session.

CPT code 64611 accurately represents chemodenervation of the salivary glands, bilateral. The use of -50, -52, or x4 modifiers is not appropriate since CPT guidelines include bilateral procedures in this code without needing additional modifiers or codes.

In the ICD-10-CM Tabular List,parentheses ( )are used to enclosenonessential modifiers, also described assupplementary words. These are words thatmay be present or absentin the diagnostic statement without affecting code assignment. This is exactly why parentheses are associated with synonyms, alternative wording, or explanatory phrases. If the provider documents the core diagnosis and the parenthetical term is missing, the code can still be correct; if the parenthetical term is present, it still points to the same code. By contrast, acolon (:)is used after an incomplete term that needs one or more additional terms to make it assignable.Brackets [ ]have other specific functions (such as enclosing synonyms in certain contexts and used with instructional content), but the standard CPC-tested definition for “synonyms/alternative wording/explanatory phrases” in the Tabular List points toparenthesesas nonessential modifiers. Knowing this distinction supports accurate code selection and reduces errors when provider wording varies.

The patient is seeing a new doctor in the same specialty group for an enlarged goiter and is undergoing a medically appropriate history and exam, along with a fine needle aspiration biopsy.

Procedure Description:

Medically appropriate history and exam.

Review of TSH results and ultrasound.

Ordering of fine needle aspiration biopsy.

CPT® Coding:

99202: Office or other outpatient visit for the evaluation and management of a new patient, which requires a medically appropriate history and/or examination and straightforward medical decision making.

Since it has been two years since the last visit and the patient is being seen by a new doctor in the same specialty group, the encounter is considered a new patient visit.

55250 = Vasectomy, bilateral procedure inherent (no modifier -50)

Z30.2 = Encounter for sterilization

Z30.012 is for contraceptive management counseling, not the procedure
