Persistently high systemic arterial blood pressure. Based on multiple readings (blood pressure determination), hypertension is currently defined as when systolic pressure is consistently greater than 140 mm hg or when diastolic pressure is consistently 90 mm hg or more. ICD-10-CM I10 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0):
Chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity. I87.331 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM I87.331 became effective on October 1, 2019.
Retinal nerve fiber layer myelinated ICD-10-CM H47.099 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0): 123 Neurological eye disorders Convert H47.099 to ICD-9-CM
Hypertension, transient– The code used is R03.0 ( Elevated blood pressure reading without diagnosis of hypertension). In case of transient hypertension in pregnancy, the codes used are from categories O13 and O14. Hypertension, Controlled – Refers to hypertension under control with treatment.
Myelinated nerve fiber layer (mNFL) is a benign clinical entity that results from an embryologic developmental anomaly whereby focal areas of the retinal nerve fiber layer fail to lose their myelin sheath. Clinically, mNFL appears as distinct white patches on the inner retinal surface.
INTRODUCTION. Myelinated retinal nerve fibres (MRNF) are rare congenital anomalies that appear as grey-white opaque lesions on the retina with feathery edges that obscure retina details. They may be located on the disc or elsewhere on the retina.
ICD-10 code H47. 10 for Unspecified papilledema is a medical classification as listed by WHO under the range - Diseases of the eye and adnexa .
By term, these myelin sheaths had become thicker, and a majority of the nerve fibers had become myelinated. In the optic nerve near the globe, myelin was first seen at term and virtually all fibers were myelinated by 7 months of age.
NeurilemmaNeurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system.
Myelinated Nerve Fibers: Myelinated nerve fibers are the nerve fibers that are insulated by a myelin sheath, allowing the faster conduction of the action potential along the nerve fiber. Unmyelinated Nerve Fibers: Unmyelinated nerve fibers are the nerve fibers that do not have a myelin sheath.
Pseudopapilledema is defined as anomalous elevation of one or both optic discs without edema of the retinal nerve fiber layer. Papilledema, on the other hand, is a swelling of the optic disc due to increased intracranial pressure.
Optic disc edema is swelling of intraocular portion of the optic nerve. The axons of retinal ganglion cell which forms the nerve exit the eye through scleral lamina cribrosa and convey the visual signal to the occipital cortex.
Papillitis, also known as optic neuritis, is characterized by inflammation and deterioration of the portion of the optic nerve known as the optic disk.
The most common cause for ON is inflammatory demyelination of the optic nerve. Demyelination is a process in which the myelin is stripped off by disease. It is believed that ON is an autoimmune process, where for some unknown reason the immune system attacks tissues of the body causing injury.
Although there are several molecular or morphological differences between nerve fibers in the PNS and CNS, the basic myelin sheath arrangement and the electrophysiological characteristics are essentially the same. Are all axons covered with myelin? No; they can be either myelinated or unmyelinated.
Myelinated nerve fibres are present in spinal and cranial nerves.
Generalized anxiety is one of the causes of white-coat hypertension. Systolic hypertension – Refers to the elevated systolic blood pressure. Gestational hypertension – High blood pressure in pregnancy. Hypertensive crisis- A severe increase in blood pressure that can lead to stroke. Hypertensive urgencies.
Hypertension: Hypertension is a very common chronic problem that many patients especially the elderly ones suffer from. Accurate documentation regarding the cause/type of hypertension is the key to accurate coding of the diagnoses related to hypertension.
Hypertensive Heart and Chronic Kidney Disease: The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease, and should be used when there is hypertension with both heart and kidney involvement.
CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease.
