2024 ICD-10-CM Diagnosis Code H44.2C9

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Retinal detachment due to high myopia

H44.2C9 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
124	OTHER DISORDERS OF THE EYE WITH MCC OR THROMBOLYTIC AGENT	02	1.3219
125	OTHER DISORDERS OF THE EYE WITHOUT MCC	02	0.7975

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.

Replacement Code

H442C9 replaces the following previously assigned ICD-10-CM code(s):

• H33.2 - Serous retinal detachment
• H44.20 - Degenerative myopia, unspecified eye
• H44.21 - Degenerative myopia, right eye
• H44.22 - Degenerative myopia, left eye
• H44.23 - Degenerative myopia, bilateral

Convert H44.2C9 to ICD-9-CM

• ICD-9-CM Code: 360.21 - Progressive high myopia
  Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
• ICD-9-CM Code: 361.9 - Retinal detachment NOS
  Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

Patient Education

Retinal Detachment

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. It provides the sharp, central vision needed for reading, driving, and seeing fine detail. A retinal detachment lifts or pulls the retina from its normal position. It can occur at any age, but it is more common in people over age 40. It affects men more than women and whites more than African Americans. A retinal detachment is also more likely to occur in people who:

• Are extremely nearsighted
• Have had a retinal detachment in the other eye
• Have a family history of retinal detachment
• Have had cataract surgery
• Have other eye diseases or disorders
• Have had an eye injury

Symptoms include an increase in the number of floaters, which are little "cobwebs" or specks that float about in your field of vision, and/or light flashes in the eye. It may also seem like there is a "curtain" over your field of vision.

A retinal detachment is a medical emergency. If not promptly treated, it can cause permanent vision loss. If you have any symptoms, see an eye care professional immediately. Treatment includes different types of surgery.
