2025 ICD-10-CM Diagnosis Code Q13.5

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Clinical Information

• Dentinogenesis Imperfecta

  an autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth. the dentin develops poorly with low mineral content while the pulp canal is obliterated.

• Dentinogenesis Imperfecta

  a congenital tooth development disorder caused by mutations in the dspp gene. the teeth are weak, discolored, and translucent.

• COL1A2 wt Allele|COL1A2|Collagen Type I Alpha 2 Chain wt Allele|Collagen, Type I, Alpha 2 Gene|OI4|Osteogenesis Imperfecta Type IV Gene

  human col1a2 wild-type allele is located in the vicinity of 7q22.1 and is approximately 37 kb in length. this allele, which encodes collagen alpha-2 (i) chain protein, plays a role in the structural integrity of tendons, ligaments and bones. mutations in the gene are associated with atypical marfan syndrome, ehlers-danlos syndrome types and osteogenesis imperfecta types.

• Osteogenesis Imperfecta Type I

  the mildest and most common type of osteogenesis imperfecta. it is characterized by bone fractures, muscle weakness, and loose joints. bone deformities are either absent or minimal.

• Osteogenesis Imperfecta Type II

  a severe form of osteogenesis imperfecta. it is characterized by bone deformities, multiple fractures, underdeveloped lungs, and often death during or after birth due to respiratory abnormalities.

• Osteogenesis Imperfecta Type III

  a type of osteogenesis imperfecta characterized by bone fractures, bone deformities, short stature, poor muscle development, barrel-shaped chest, and triangular face.

• Osteogenesis Imperfecta Type IV

  a type of osteogenesis imperfecta that is characterized by fractures and hearing loss. it is more severe than type i and less severe than types ii and iii.

MS-DRG Mapping for ICD-10-CM Code Q13.5

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

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 V42.0 applicable from 10/01/2024 through 09/30/2025.

Present on Admission (POA)

Q13.5 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Convert Q13.5 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include:

• Refractive errors
• Cataracts - clouded lenses
• Optic nerve disorders, including glaucoma
• Retinal disorders - problems with the nerve layer at the back of the eye
• Macular degeneration - a disease that destroys sharp, central vision
• Diabetic eye problems
• Conjunctivitis - an infection also known as pink eye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
