List-A-Code™  ICD-10-CM

Age range 15-124 years inclusive

Presence of a complication or condition that increases the severity of a patient's condition, affects DRG assignment, and increases the resources needed to care for the patient appropriately.

The Chronic Condition Indicator provides an easy way for users to categorize ICD-10-CM diagnosis codes into one of two categories: chronic or not chronic. Examples of chronic conditions include conditions such as malignancies, diabetes, most forms of mental illness, hypertension, many forms of heart disease, and congenital anomalies. Not chronic conditions include conditions such as infections, pregnancy, many neonatal conditions, nonspecific symptoms, and injuries.

This instructional note indicates that another code may be required to fully explain a condition, but the order they are sequenced in depends on whichever is the primary reason for an encounter.

This instructional note points to a code which must be sequenced before the code this instructional note falls under.

Codes mentioned in the American Psychiatric Association's DSM-5 publication. This indicator is useful for those working in the field of behavioral health or in an integrated care practice.

This instructional note conveys which codes cannot be coded with the code it falls under.

This instructional note conveys codes which can co-exist with the code it falls under, but must be coded separately.

Female-related only

This instructional note further defines the content of the category.

Male-related only

Describes the manifestation of an underlying disease, not the disease itself. Code first the underlying disease followed by the manifestation code.

Age range 12-55 years inclusive

Presence of a major complication or condition that increases the severity of a patient's condition, affects DRG assignment, and increases the resources needed to care for the patient appropriately.

Age range 0-28 days inclusive

There are selected codes that describe a circumstance which influences an individual's health status, but not a current illness or injury, or codes that are not specific manifestation but they may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis. The following unacceptable principal diagnosis code is considered "acceptable" when a secondary diagnosis is also coded on the record. Example: Z51.89 Encounter for other specified aftercare

Diagnosis is a combination code in ICD-10-CM, which also represents the MCC. In ICD-9-CM, it was represented by two or more codes one of which was the CC.

Age range 0-17 inclusive

Diagnosis codes that cannot be listed as Present on Admission. They are exempt from POA use.

Some diagnosis are not usually sufficient justification for admission to an acute care hospital. For example, if a patient is given code R03.0 for elevated blood pressure reading, without diagnosis of hypertension, then the patient would have a questionable admission, since an elevated blood pressure reading is not normally sufficient justification for admission to a hospital.

Codes located in Chapter 21 that begin with the letter "Z" and can only be reported as first-listed or principal diagnosis.
