Ruby Adjustable Style CPAP Chinstrap

By Spirit Medical  |  HCPCS: A7036

Continuous Single-Strap Design — Less Slippage  |  Ultra-Wide Comfort Bands  |  Breath-O-Prene Material  |  Two Velcro Adjusters — Easy On/Off  |  Available in Standard & Extra Large  |  HCPCS A7036

The Ruby Adjustable Style CPAP Chinstrap keeps the mouth closed during CPAP, BiPAP, and APAP therapy through a flowing continuous single-strap design that wraps the chin and head in one unbroken band — a geometry that distributes holding force evenly and resists the positional slippage common in two-piece or two-band designs that can separate and shift during sleep. The ultra-wide comfort bands maximize the contact surface against the skin, spreading the holding pressure over a larger area for a more comfortable, less concentrated feel throughout the night. The soft breath-o-prene material is breathable and skin-friendly for extended wear during sleep. Two velcro adjusters make it quick to put on and take off and allow a precise custom fit across the adjustment range. Available in Standard (adjusts to a maximum of approximately 22–24 inches) and Extra Large (adjusts to a maximum of approximately 26–28 inches). HCPCS A7036. By Spirit Medical.

Sizing tip: if you are between sizes or near the upper end of the Standard's range, order the Extra Large for more comfortable velcro overlap and longer usable strap life. Call 1-866-218-0902 with sizing questions.

Key Features

• Continuous single-strap design — anti-slippage geometry — unlike conventional two-piece chinstraps where a chin band and a head strap are joined at connection points that can shift during sleep position changes, the Ruby's design uses a single continuous flowing band that wraps chin and head together; there are no junction points to separate or slide, and the continuous tension distributes holding force consistently around the entire wrap path rather than concentrating it at attachment points
• Ultra-wide comfort bands — the strap's width is designed to maximize skin contact area under the chin and along the cheeks; wider contact spreads the holding pressure over more surface area, reducing the pressure per square inch at any single point and making the strap less noticeable during extended wear through the night
• Breath-O-Prene material — a soft, breathable neoprene-type material that allows airflow through the strap fabric, reducing heat and moisture buildup under the chinstrap during sleep; more comfortable for prolonged nightly wear than non-breathable neoprene or rigid materials
• Two velcro adjusters — the strap fastens with two velcro closure points that allow independent adjustment of fit; makes the chinstrap quick to put on before therapy and easy to remove after; velcro allows fine-tuning of tension without fixed buckle positions
• Two sizes — Standard and Extra Large — Standard adjusts up to approximately 22–24 inches (head + chin circumference); Extra Large adjusts up to approximately 26–28 inches; the two-size offering accommodates a broader range of head sizes than one-size-fits-most designs
• HCPCS A7036 — the standard insurance billing code for a CPAP chinstrap

Clinical FAQs

How does the Ruby's continuous single-strap design resist slippage better than a standard chinstrap?

Most CPAP chinstraps use a design where a chin cup or chin band is connected to one or more separate head straps — the chin portion holds the jaw, and the head strap portion anchors it to the skull, with the two joined at side connection points near the ears. During sleep, particularly in side sleepers who press the head into a pillow or shift positions frequently, these junction points are lever points where the chin section and head section can pull apart from each other. When the chin section slips forward or down relative to the head band, the holding tension on the jaw is reduced or lost — the mouth opens and the chinstrap has effectively failed for the rest of the sleep session. The Ruby's continuous single-strap design eliminates these junction points: the strap is one unbroken band that wraps the chin from below and the head from behind in a continuous loop. There is no connection point to separate, and no chin section that can shift independently from the head section. The tension throughout the strap is shared across the entire loop rather than localized at attachment points. This makes the chin-holding force more resistant to positional disruption during sleep movement. For users who have tried standard two-piece chinstraps and found them sliding or shifting during the night, the continuous-band geometry is a meaningfully different approach worth trying.

How do I know whether to order Standard or Extra Large?

The Ruby Adjustable is available in Standard (adjusts up to approximately 22–24 inches) and Extra Large (adjusts up to approximately 26–28 inches). The measurement the size refers to is the full wrap circumference — from the chin, up each side of the face, and around the back of the head. To estimate your size, measure loosely around your lower head and chin in the path the chinstrap would follow. If that circumference is 22 inches or under, Standard will fit with comfortable velcro overlap. If it is 22–24 inches, Standard will fit but may be near its maximum adjustment range, which reduces the amount of velcro contact and can make the closure less secure over time as the velcro wears. If it is over 22 inches, Extra Large is the better choice for a more comfortable fit with adequate velcro overlap. A practical rule of thumb from user experience: if you have a larger-than-average head size, wear a hat size larger than medium, or have had other chinstraps feel tight, order the Extra Large. The Extra Large costs the same, and choosing one size up is easier to correct by tightening the velcro than choosing too small and running out of adjustment range. Questions about sizing?

Is a CPAP chinstrap covered by insurance, and what is HCPCS code A7036?

HCPCS code A7036 is the standard DMEPOS billing code for a CPAP chinstrap — specifically defined as "Chinstrap, used with positive airway pressure device." The Ruby Adjustable Chinstrap carries this HCPCS code and is a covered supply item under Medicare Part B and most commercial insurance plans that include CPAP/BiPAP supply benefits. Medicare and many plans cover a replacement chinstrap once every 6 months for active CPAP therapy patients — the chinstrap is considered a wearing supply that degrades over time from nightly use, washing, and velcro wear. Coverage requires that the patient have an active, valid CPAP or BiPAP prescription and that the chinstrap is documented as medically necessary (typically as part of the therapy management for obstructive sleep apnea). The DME supplier must be enrolled with the patient's insurance plan. Medical Department Store is a licensed DMEPOS supplier — call us at 1-866-218-0902 to discuss whether your plan covers the Ruby Chinstrap and what documentation your insurer requires for the claim.
