ICD-9-CM code 433 indicates occlusion and stenosis of precerebral arteries; code 434, occlusion of cerebral arteries; code 436, acute but ill-defined cerebrovascular disease.
ICD-10 code I67. 9 for Cerebrovascular disease, unspecified is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
In ICD-9, essential hypertension was coded using 401.0 (malignant), 401.1 (benign), or 401.9 (unspecified). ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease. That code is I10, Essential (primary) hypertension.
9.
I63. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Obstruction in blood flow (ischemia) to the brain can lead to permanent damage. This is called a cerebrovascular accident (CVA). It is also known as cerebral infarction or stroke. Rupture of an artery with bleeding into the brain (hemorrhage) is called a CVA, too.
401.9 - Unspecified essential hypertension | ICD-10-CM.
In ICD-10, the diagnosis codes are simplified and the hypertension table is no longer necessary. The concept of controlled and uncontrolled are not a part of the coding choice, although good clinical documentation should include the status of the patient and the type of hypertension being treated.
ICD-10-CM Code for Elevated blood-pressure reading, without diagnosis of hypertension R03. 0.
Z12. 11: Encounter for screening for malignant neoplasm of the colon.
No specific diagnosis is required for the Annual Wellness Visit, but Z00. 00 or Z00. 01 is appropriate for the Annual Routine Physical Exam. A Depression Screening (G0444) is a required component within the initial Annual Wellness Visit (G0438) and should not be billed separately.
Applicable To. Screening is the testing for disease or disease precursors in asymptomatic individuals so that early detection and treatment can be provided for those who test positive for the disease.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an exact match to ICD-9 code 437.9:
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
437.9 is a legacy non-billable code used to specify a medical diagnosis of unspecified cerebrovascular disease. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
References found for the code 437.9 in the Index of Diseases and Injuries:
The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating.
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
