2025 ICD-10-CM code F51.3

Sleepwalking (somnambulism): A non-rapid eye movement (NREM) sleep arousal disorder characterized by repeated episodes of rising from bed and walking while asleep.

Follow current ICD-10-CM coding guidelines.Ensure that all relevant conditions are properly documented.

No specific modifiers are typically used with F51.3. Modifiers may be applied in specific scenarios based on circumstances of care.

Medical necessity is established by the presence of recurrent sleepwalking episodes causing significant distress, functional impairment, or risk of harm to the patient or others.The documentation must support the clinical significance and the need for the evaluation and treatment.

The clinical responsibility includes obtaining a detailed patient history, performing a physical and mental status examination, ordering and interpreting any necessary diagnostic studies such as polysomnography, making the diagnosis, and developing and implementing a treatment plan.This may involve counseling, medication management, and/or referral to other specialists.

IMPORTANT May be coded in conjunction with other codes describing associated behaviors or injuries sustained during episodes.ICD-9-CM equivalent is 307.46.

In simple words: Sleepwalking, or somnambulism, happens when someone walks around while they're still asleep. It's most common in children and rarely occurs in adults.People who sleepwalk don't remember doing it, and they might seem disoriented or unresponsive.Treatment focuses on improving sleep habits, managing stress, and sometimes involves medication.

Sleepwalking, also known as somnambulism, is a non-rapid eye movement (NREM) sleep arousal disorder.It involves rising from bed and walking while still asleep, typically occurring within an hour or two after falling into deep sleep.Episodes usually last 5-15 minutes, and individuals often have no memory of the event.Symptoms may include disorientation, unresponsiveness, a glazed expression, and potentially engaging in routine activities or exhibiting violent behavior. Diagnosis is based on patient history, symptoms, and a thorough examination, potentially including polysomnography. Treatment may involve creating a relaxing sleep environment, arousal techniques before anticipated episodes, improved sleep hygiene, addressing underlying medical or psychological conditions, medication adjustments, counseling, hypnosis, or the use of benzodiazepines or antidepressants.

Example 1: A 7-year-old child is brought to the clinic by their parents due to repeated episodes of sleepwalking. The child is found to sleepwalk 2-3 times per week, often leaving their bedroom and wandering around the house. The child does not recall these episodes and displays no other concerning symptoms., A 25-year-old woman presents with sleepwalking episodes occurring 1-2 times per month following the recent death of a loved one. These episodes are infrequent and short in duration, but have caused concern amongst the patient and their family., A 55-year-old male patient, experiencing multiple episodes of sleepwalking per week, presents to the Emergency Room following an injury sustained during an episode. The patient was found in a confused state on the floor and reports no memory of the incident.This is the third instance of this sort in the last six months.

Detailed patient history including frequency, duration, and circumstances of sleepwalking episodes.Description of any associated behaviors (e.g., talking, violence).Documentation of any injuries sustained during episodes. Results of physical examination, and if performed, polysomnography.

** Consider using additional codes to specify any associated symptoms or conditions (e.g., sleep-related eating disorder, sleep-related sexual behavior).
