Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I27.81:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Cor pulmonale NOS
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- acute cor pulmonale I26.0
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I27.81 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Chronic cor pulmonale
- Chronic right-sided heart failure
- Cor pulmonale
- PULMONARY HEART DISEASE-. hypertrophy and dilation of the right ventricle of the heart that is caused by pulmonary hypertension. this condition is often associated with pulmonary parenchymal or vascular diseases such as chronic obstructive pulmonary disease and pulmonary embolism.
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|314||OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC||05||2.0834|
|315||OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC||05||0.9752|
|316||OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC||05||0.7495|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert I27.81 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I27.81 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Pulmonary hypertension (PH) is high blood pressure in the arteries to your lungs. It is a serious condition. If you have it, the blood vessels that carry blood from your heart to your lungs become hard and narrow. Your heart has to work harder to pump the blood through. Over time, your heart weakens and cannot do its job and you can develop heart failure.
Symptoms of PH include
- Shortness of breath during routine activity, such as climbing two flights of stairs
- Chest pain
- A racing heartbeat
- Pain on the upper right side of the abdomen
- Decreased appetite
As PH worsens, you may find it hard to do any physical activities.
There are two main kinds of PH. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease.
There is no cure for PH. Treatments can control symptoms. They involve treating the heart or lung disease, medicines, oxygen, and sometimes lung transplantation.
