Study Notes

Carcinoma in Situ

Refers to tumor cells in the initial stage of malignancy, remaining confined to the original site without invading surrounding tissue.
Common example includes intraepithelial infiltrating.

Patient Cases and Diagnoses

Elevated CPK and MB enzymes, along with ST changes on an EKG, may indicate a myocardial infarction (MI).
For urinary tract infections, Escherichia coli is coded as a secondary diagnosis when a definitive diagnosis is provided.
In cases of post-heart transplant patients with unclear documentation, coders should query the physician for clarity.
Symptoms like loss of interest, weight gain, fatigued state, and sleep difficulties suggest a diagnosis of major depression.

Inpatient Admission Coding Examples

A patient with AIDS underwent an inguinal herniorrhaphy; necessary ICD-10 codes include K40.90 for hernia and B20 for AIDS.
A 75-year-old presented with dehydration post-stroke; codes related to dehydration and I69.391 for stroke should be used.
Alcohol detoxification with liver cirrhosis would require coding for both conditions, including F10.229 for alcohol dependence.
For exploratory laparotomy due to intestinal obstruction, only abdominal adhesions with obstruction will be coded, excluding abdominal pain as it is merely a symptom.

Diagnosis and Treatment Procedures

Pneumonia treated with IV antibiotics takes precedence in coding over atrial fibrillation managed with oral medications.
Women giving birth may require coding for hemorrhage occurring after delivery but before placenta expulsion.
For cancer treatments such as lobectomy for lung cancer, both primary and metastatic sites must be accurately coded.
Documentation of patient care and responses, such as treatment records, must be adequately reflected in medical records.

Outpatient and Ambulatory Coding Examples

Noncardiac chest pain and tests like esophageal acid reflux require specific ICD-10-CM and CPT codes.
Annual screening mammograms and excisions of basal cell carcinoma have designated diagnostic and procedural codes for accurate tracking.
Surgical procedures like hysteroscopy for dysfunctional uterine bleeding must document both the action taken and the associated conditions.

Documentation and Authentication

Key aspects of medical record adequacy include clear documentation of patient care actions and their responses.
Authentication of entries serves to verify the authorship and integrity of medical documents, requiring signatures for validation.
Regulations delineated in medical staff bylaws outline necessary documentation requirements and penalties for noncompliance.

Overall Diagnosis Coding Considerations

The act of coding for multiple conditions must adhere to guidelines that prioritize definitive diagnoses over mere symptoms.
Changes in coding based on additional complications (e.g., aspiration pneumonia due to dysphagia) affect health classifications and reimbursement structures.
Proper coding of treatments and diagnoses involves reviewing operative reports and citing specifics of patient conditions for accuracy and compliance with regulations.### Screening Colonoscopy Coding
Z12.11: Used for encounters involving screening for malignant neoplasm of the colon.
D12.6: Represents benign neoplasm of the colon, unspecified.
Correct coding sequence prioritizes screening colonoscopy (Z12.11) followed by the polyp code (D12.6).
Option c (Z12.11, D12.6) is the correct coding sequence.

Benign Neoplasms of Skin Coding

Category D23 includes other benign neoplasms of skin, including those of hair follicles, sebaceous glands, and sweat glands.
Excludes benign lipomatous neoplasms and melanocytic nevi; these should not be coded under D23.
Correct code for benign neoplasm of sweat glands is found in category D23, making option a correct.

Coding for Benign Lipomatous Neoplasms

When coding benign lipomatous neoplasms of the skin, the appropriate range is D17.0-D17.3.
D23 is not applicable for benign lipomatous neoplasms, thus option b is the correct choice.

Multiple Diagnoses Discharge Coding

Relevant diagnoses include posterior subcapsular cataract in right eye, diabetes mellitus, hypertension, and mild acute renal failure.
E11.9: Code for Type 2 diabetes mellitus without complications.
H25.041: Correct code for posterior subcapsular polar age-related cataract in right eye.
I10: Represents essential hypertension but does not combine with acute renal failure as it is temporary.
N17.9: Code for unspecified acute kidney failure.
Correct combination of codes for this discharge is option b (H25.041, E11.9, I10, N17.9).

Coding Acute Exacerbation of COPD

Acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) is coded as J44.1.
Hypertension is documented alongside chronic renal disease, requiring combined coding due to their relationship.
Stage of chronic kidney disease must also be accounted for in the coding process.
