Combination codes are used to classify two diagnoses, a diagnosis with a manifestation, or a diagnosis with an associated complication. A complication is a condition that arises during the hospital stay that prolongs the length of stay by at least one day in approximately 75 percent of cases1. Complications may affect payment and severity of illness and risk of mortality classifications. Examples of combination codes that include a diagnosis with an associated complication are:

• I50.23 Acute on chronic systolic (congestive) heart failure
• K57.21 Diverticulitis of large intestine with perforation and abscess with bleeding
• O34.211 Maternal care for incompetent cervix with cerclage, first trimester

A diagnosis that is an integral part of a disease process is not a valid option for combination codes, because it does not represent a separate or additional condition that needs to be coded. For example, chest pain is an integral part of acute myocardial infarction and does not require a separate code.

A diagnosis with an associated procedure is not a valid option for combination codes, because procedures are coded separately from diagnoses using ICD-10-PCS codes. For example, appendicitis with appendectomy is not a combination code, but rather two codes: one for the diagnosis (K35.80 Acute appendicitis without perforation or gangrene) and one for the procedure (0DTJ4ZZ Resection of appendix, percutaneous endoscopic approach).

A diagnosis with a sequelae or late effect is not a valid option for combination codes, because sequelae or late effects are coded separately from the original condition using the appropriate code from category B90-B94 Sequelae of infectious and parasitic diseases or category I69 Sequelae of cerebrovascular disease, followed by the code for the specific condition2. For example, hemiplegia following cerebral infarction is not a combination code, but rather two codes: one for the sequelae (I69.351 Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side) and one for the original condition (I63.9 Cerebral infarction, unspecified).

According to the AHIMA CDIP Exam Preparation Guide, the adjusted case mix index (CMI) is a measure that demonstrates the relative severity and complexity of patients treated in a hospital, and is used to evaluate the financial impact of a hospital’s clinical documentation integrity (CDI) program1. The adjusted CMI is calculated by multiplying the unadjusted CMI by a factor that accounts for the percentage of Medicare patients in the hospital2. The higher the adjusted CMI, the higher the expected reimbursement per patient, and the more effective the CDI program is assumed to be3. The other options are not correct because they do not measure the severity and complexity of patients or the financial impact of CDI. Hospital acquired conditions (HACs) are conditions that are not present on admission and are considered preventable by CMS, and may result in reduced reimbursement or penalties4. The program for evaluating payment patterns electronic report (PEPPER) is a report that provides hospital-specific data on potential overpayments or underpayments for certain services or diagnoses, and helps identify areas of risk or opportunity for improvement. Present on admission (POA) indicators are codes that indicate whether a condition was present at the time of admission or acquired during the hospital stay, and affect the assignment of DRGs and HACs. References:

 Severity of illness (SOI) and risk of mortality (ROM) are two metrics that measure the complexity and acuity of a patient’s condition, based on the number, nature, and interaction of complications and comorbidities (CCs) and major CCs (MCCs). SOI reflects the extent of physiologic decompensation or organ system loss of function, while ROM reflects the likelihood of dying. Both SOI and ROM are divided into four levels: minor, moderate, major, or extreme. These metrics are used to adjust payment rates, quality indicators, and performance measures for hospitals and other healthcare providers.

If a CDIP stops reviewing any record after a major CC is found, they may miss other CCs or MCCs that could affect the patient’s SOI and ROM levels. For example, a patient with pneumonia and sepsis would have a major CC (pneumonia) and an MCC (sepsis). If the CDIP stops reviewing the record after finding pneumonia, they would not capture sepsis, which would increase the patient’s SOI and ROM levels from major to extreme. This would result in underreporting the patient’s true complexity and acuity, and potentially lead to lower reimbursement, lower quality scores, and higher denial risk.

Therefore, the unintended consequence of this policy is a decrease in SOI and ROM levels for patients who have more than one CC or MCC.
