ICD 10 Coding Alert

G47.0- codes: These codes are a sort of catch-all group for use when notes are vague or the condition hasn’t been too deeply explored:

• G47.00 (Insomnia, unspecified)
• G47.01 (Insomnia due to medical condition)
• G47.09 (Other insomnia)

Take a look at the extensive Excludes2 list. There are several specific types of insomnia for which payers will accept one of the general codes listed above. This proves that the conditions listed in the note are different, despite “insomnia” being in the name. See also the note under G47.01, which instructs you to code also the associated medical condition. This is not to be confused with the next code family, which includes insomnia that’s due to a mental disorder.

F51.0- codes: These codes include a variety of more specific codes that relate to mental conditions:

• F51.01 (Primary insomnia)
• F51.02 (Adjustment insomnia)
• F51.03 (Paradoxical insomnia)
• F51.04 (Psychophysiologic insomnia)
• F51.05 (Insomnia due to other mental disorder)
• F51.09 (Other insomnia not due to a substance or known physiological condition)

These also feature a sizable list of Excludes2 notes, indicating your ability to pair F51.0- with other types of insomnia, including G47.0-.

Look to Other F Codes for Other Issues

If your provider notes other types of sleep disturbances, such as nightmares, these conditions may or may not lead to insomnia. However, they still tell a valuable story and should be in the patient’s record:

• F51.3 (Sleepwalking [somnambulism])
• F51.4 (Sleep terrors [night terrors])
• F51.5 (Nightmare disorder)

Note: To report periodic nightmares, code either of the following, depending on the provider’s documentation:

• F51.8 (Other sleep disorders not due to a substance or known physiological condition)
• F51.9 (Sleep disorder not due to a substance or known physiological condition, unspecified)

For Kids, Look to Notes Before Assigning Colic Codes

Colic is a common pediatric condition affecting patients under 6 months of age that can lead to insomnia and sleep disturbances. When you look in the alphabetic index, you’ll first see R10.83 (Colic).

However, if the colic occurs in a patient over 12 months old, you’ll need to use a code such as R10.84 (Generalized abdominal pain) instead of R10.83, per the Excludes1 note mentioned by the colic code in the ICD-10. Another Excludes1 code worth mentioning, which is listed for all R10 codes, is N23 (Unspecified renal colic). While rare in infants, you’ll report N23 if your gastroenteritis documents stomach pain associated with this particular form of colic.

Get Specific When Reporting Pediatric Sleep Apnea

Newborns can have a variety of types of apnea, and ICD-10-CM allows you to report apnea in children to the 5th character. That means that the greater the documented details, the better.

Remember, apnea is defined as the stoppage of respiratory airflow for at least 20 seconds.

Central apnea occurs when breathing stops due to poor or no muscle coordination.

Obstructive apnea occurs when breathing stops due to an obstruction in the airway.

Mixed apnea is an episode where central and obstructive forces are present.

Sleep apnea definitions are similar, but symptoms occur during sleep.

“Apnea is a symptom that has many possible etiologies,” explains Donna Walaszek, CCS-P, billing manager, credentialing/coding specialist for Northampton Area Pediatrics LLP in Northampton, Massachusetts. This is why ICD-10-CM has assigned codes to several types of newborn apnea, in turn making P28.3- and P28.4- parent (non-billable) codes:

• P28.30 (Primary sleep apnea of newborn, unspecified)
• P28.31 (Primary central sleep apnea of newborn)
• P28.32 (Primary obstructive sleep apnea of newborn)
• P28.33 (Primary mixed sleep apnea of newborn)
• P28.39 (Other primary sleep apnea of newborn)
• P28.40 (Unspecified apnea of newborn)
• P28.41 (Central neonatal apnea of newborn)
• P28.42 (Obstructive apnea of newborn)
• P28.43 (Mixed neonatal apnea of newborn)
• P28.49 (Other apnea of newborn)

Note: Evaluations for some pediatric conditions, such as autism spectrum disorder, include a workup of co-occurring conditions like sleep disorder. If such an evaluation were to determine that a patient’s apnea has its origin not in something like obesity, but rather in the perinatal period, no matter the age at which the evaluation is performed, you’ll report a P28- code. Section I.C.16.a.1 of the ICD-10-CM Guidelines directs coders that “Chapter 16 codes may be used throughout the life of the patient if the condition is still present.”

E/M May Be Appropriate Even Without Patient Visit

Sometimes, sleep disturbances can be embarrassing, especially if the child is experiencing bedwetting, or enuresis, past when is considered the norm.

Consider a scenario where the parents of a 12-year-old patient present in the office to discuss their child’s bedwetting. The pediatrician spoke to them about the child’s condition and made a plan with the family. It is perfectly possible to bill for an appropriate level of office/outpatient evaluation and management (E/M) service in situations like this, such as 99212 (Office or other outpatient visit for the evaluation and management of an established patient, which requires a medically appropriate history and/or examination and straightforward medical decision making…).

That’s because CPT^® defines total time for office/outpatient E/M services as including “counseling and educating the patient/family/caregiver.” Under this situation, family counseling without the patient would qualify.

Further, CPT^®’s Counseling Guidelines state that “counseling is a discussion with a patient and/or family,” (emphasis added). The “or” here can be taken to mean that the patient does not have to be present.

Note: Some payers may interpret these guidelines differently and may insist that the patient be present during the encounter in order for you to be reimbursed for the office/outpatient E/M service. Make sure you verify a specific payer’s policy before billing.
