Frozen section pathology coding rules:

88331 – Frozen section, first tissue block, each specimen

88332 – Frozen section, each additional tissue block, same specimen

Breakdown:

Specimen 1

Block 1 → 88331 × 1

Block 2 → 88332 × 1

Specimen 2

Block 1 → 88331 × 1

Block 2 → 88332 × 1

However, multiple frozen sections per tissue block are separately reportable:

Total first blocks = 4 frozen sections → 88331 × 4

Total additional blocks = 3 frozen sections → 88332 × 3

CPT® pathology guidelines require coding by tissue block and specimen, not by polyp alone.

For a complete bilateral mastectomy with insertion of breast prosthesis performed during the same surgical session, the correct CPT® codes are:

1. 19303-50: This code represents a complete mastectomy (removal of breast tissue) performed bilaterally (indicated by the -50 modifier).

2. 19340-50: This code is for the immediate insertion of a breast prosthesis following mastectomy, also performed bilaterally.

Explanation of other options:

A. 19303-50, 19342-50: Incorrect because 19342 is for the insertion of a breast implant, which differs from a prosthesis.

B. 19305-50, 19340-50: 19305 describes a modified radical mastectomy, which is more extensive than what is documented here.

C. 19325-50: This code represents a breast augmentation procedure, not a mastectomy with prosthesis insertion.

Thus, the correct answer is D. 19303-50, 19340-50, which accurately describes a bilateral mastectomy with prosthesis insertion.

To determine the correct anesthesia code for a cesarean delivery with specific conditions, we review the following codes:

01961 is defined as "Anesthesia for cesarean delivery only," which aligns with this scenario, as the patient is admitted for a cesarean section.

01960 refers to anesthesia for a vaginal delivery, which does not apply here as the delivery is via cesarean.

01967 is for "Anesthesia for planned vaginal delivery," which also does not apply due to the cesarean route.

01958 is used for planned vaginal delivery that may involve a complicated scenario, but since the procedure is a cesarean section, this code is not appropriate.

Given that the patient is in labor for a cesarean section and has had a previous external cephalic version, 01961 is the correct answer.

Procedure: Impedance testing via tympanometry is performed to assess hearing loss in the left ear.

CPT® Code:

92567: This code is for tympanometry (impedance testing) without reflex threshold measurements.

Code Selection Justification: The procedure involved tympanometry without reflex threshold, which is specifically coded as 92567.

Brackets [ ] in the ICD-10-CM Alphabetic Index are used to identify manifestation codes.

These codes cannot be reported as the principal diagnosis and must be sequenced after the underlying condition.

This is a frequently tested ICD-10-CM guideline concept.

To determine the correct E/M code, we need to consider the three key components: history, examination, and medical decision making (MDM).

History:

The documentation indicates an expanded problem-focused history. This is supported by the detailed history of present illness, including the patient's description of symptoms, family history, and review of systems with pertinent positives and negatives.

Examination:

The examination is also expanded problem-focused. The physician focused on the relevant systems (head, neck, throat) and documented specific findings related to the chief complaint (thyromegaly).

Medical Decision Making:

The MDM is straightforward. The physician is evaluating a new problem (bilateral thyroid nodules) with a low level of risk. Although further workup is planned, this alone doesn't automatically increase the MDM complexity.

Based on these components, 99213 is the most appropriate code.

Why other options are incorrect:

99212: Requires a problem-focused history and examination, which is less comprehensive than what was documented.

99214 and 99215: Require a higher level of MDM (low or moderate complexity) and/or a more detailed examination. The documentation doesn't support this level of service.

CPT Code 00811: Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to the splenic flexure; diagnostic, with or without collection of specimen(s) by brushing or washing

This code is reported for anesthesia services provided during a colonoscopy that is diagnostic in nature.

ICD-10-CM Code D62: Acute posthemorrhagic anemia

This is the most accurate postoperative diagnosis. The operative report states "Anemia due to acute blood loss."

ICD-10-CM Code N18.6: End stage renal disease

This code captures the patient's documented history of ESRD.

ICD-10-CM Code Z99.2: Dependence on renal dialysis

This code is necessary to report the patient's dialysis status, as it affects the overall risk of the procedure.

Why other options are incorrect:

00812: This code is for therapeutic colonoscopies, not diagnostic.

D64.9: This code is for anemia, unspecified. D62 is more specific to the patient's condition.

K62.5: This code is for lower gastrointestinal bleeding, but the anemia is the primary diagnosis in this case.

Diabetic polyneuropathy is coded as E11.42, which indicates type 2 diabetes mellitus with diabetic polyneuropathy. The ICD-10-CM guidelines direct that when a patient has both diabetes and polyneuropathy, a single combination code is used to capture both conditions.

ICD-10-CM (current year), Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00-E89), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.4.a.6.

The procedure described involves a LeFort I reconstruction, which is a type of orthognathic surgery performed to correct deformities of the midface. In this scenario, the surgeon performed the reconstruction in two pieces, moving the upper jawbone forward and repositioning the teeth of the maxilla. According to the CPT® guidelines, CPT code 21146 describes a LeFort I (maxilla only) osteotomy, two-piece segment, including bone grafts (includes obtaining autografts). This code matches the description provided.

In the ICD-10-CM Tabular List, square brackets [ ] (Brackets) are used to enclose synonyms, alternative wording, or explanatory phrases. This is a punctuation convention taught for ICD-10-CM and is tested on CPC.

To avoid confusion with other punctuation:

Parentheses ( ) indicate nonessential modifiers (supplementary words that may be present or absent without affecting the code selection).

A semicolon ( ; ) is used in the Tabular List to show that additional modifying words (that follow the semicolon) are required to complete the diagnostic statement.

Colons ( : ) are used after an incomplete term that needs one or more modifying terms to make it assignable.
