Clinical Information

• Hypotrichosis

  presence of less than the normal amount of hair. (dorland, 27th ed)

• Alopecia

  absence of hair from areas where it is normally present.

• Alopecia Areata

  loss of scalp and body hair involving microscopically inflammatory patchy areas.

• Mucinosis, Follicular

  a disease of the pilosebaceous unit, presenting clinically as grouped follicular papules or plaques with associated hair loss. it is caused by mucinous infiltration of tissues, and usually involving the scalp, face, and neck. it may be primary (idiopathic) or secondary to mycosis fungoides or reticulosis.

• Hypotrichosis

  a congenital condition, usually due to genetic aberrations, that is characterized by a lack of hair growth on the head and/or body.

• Roberts-SC Phocomelia Syndrome|Hypomelia Hypotrichosis Facial Hemangioma Syndrome|Phocomelia-Pseudothalidomide Syndrome|Pseudothalidomide Syndrome|SC Phocomelia Syndrome

  a rare genetic syndrome with an autosomal recessive pattern of inheritance. it is caused by a mutation in the esco2 gene. clinical signs at birth include multiple limb and facial abnormalities. it is considered to be a mild variant of roberts syndrome.

L65.9 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.

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 L65.9 to ICD-9-CM

• ICD-9-CM Code: 704.00 - Alopecia NOS
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Hair Loss

You lose up to 100 hairs from your scalp every day. That's normal, and in most people, those hairs grow back. But many men -- and some women -- lose hair as they grow older. You can also lose your hair if you have certain diseases, such as thyroid problems, diabetes, or lupus. If you take certain medicines or have chemotherapy for cancer, you may also lose your hair. Other causes are stress, a low protein diet, a family history, or poor nutrition.

Treatment for hair loss depends on the cause. In some cases, treating the underlying cause will correct the problem. Other treatments include medicines and hair restoration.
