Questions we often hear from directors, office managers and medical clerks at clinics that provide CPAP therapy for sleep apnea: "Can our clinic file for the CPAP enhanced management system addition?", "How is the 40% usage standard counted?", and "Are there patients for whom we must not bill management fee 2?" This article organizes the points, billing rules, facility standards and notification, based on the FY2026 fee schedule (MHLW Public Notice No. 69), the interpretive notice (Hoi-hatsu 0305 No. 6) and the facility standards notice for special medical treatment fees (Hoi-hatsu 0305 No. 8).
Disclaimer: This article is general information based on public documents as of November 3, 2026. The official notices of the Ministry of Health, Labour and Welfare (MHLW) and the guidance of your regional Bureau of Health and Welfare are authoritative. Always confirm billing and notification decisions against the latest original texts and your regional bureau.
Overview: C107-2 and related points
Guidance for patients receiving home CPAP (continuous positive airway pressure) therapy is evaluated under "C107-2 Home CPAP Therapy Management Fee." The points in the notice are as follows.
| Item | Points | Description |
|---|---|---|
| C107-2 (1) Management fee 1 | 2,250 | Certain heart failure patients on ASV therapy, etc. (below) |
| C107-2 (2) Management fee 2 | 240 | SAS patients on CPAP therapy, etc. |
| Note 2: Enhanced management system addition | 15 | Added to (2); facility standard notification required |
| Note 3: Remote monitoring addition | 150 × months | Added to (2); CPAP patients; up to 2 months |
| Note 4: Via information and communication devices | 218 | Billed instead of the 240 points of (2) |
| C165 Home CPAP therapy device addition | ASV 3,750 / CPAP 960 | When a device is used |
| C171-2 Home CPAP therapy materials addition | 100 | When equipment is used |
Note that the enhanced management system addition can be added to management fee 2 only (Note 2 of the notice).
Eligible patients: fee 1 vs. fee 2
The interpretive notice distinguishes them as follows.
- Fee 1: Chronic heart failure patients with NYHA class III or higher, Cheyne-Stokes respiration during sleep and an apnea-hypopnea index (AHI) of 20 or more on polysomnography, who still had an AHI above 15 under CPAP and were placed on ASV therapy (both conditions must apply)
- Fee 2: Any of the following (a)–(c)
- (a) Heart failure patients as above, not covered by fee 1, who receive ASV therapy
- (b) Heart failure patients who must continue ASV therapy while heeding the ASV appropriate-use statement of the Japanese Circulation Society and the Japanese Heart Failure Society
- (c) Patients meeting all of (i)–(iii) (if AHI is 30 or more, (ii) alone is enough)
- (i) AHI (apneas plus hypopneas per hour) of 15 or more
- (ii) Strong symptoms such as daytime sleepiness or morning headache that interfere with daily life
- (iii) On polysomnography, fragmented sleep and markedly reduced or absent deep sleep due to frequent apneas, which normalize under CPAP
Common rules in the notice:
- Treatment status is evaluated for up to 2 months after the start; only cases judged suitable to continue remain billable
- When billing the management fee, the CPAP device is loaned to the patient by the medical institution
When not to bill management fee 2 (usage check)
Interpretive notice item (6) covers SAS patients meeting condition (c) who are on CPAP. Using equipment that can monitor usage, if the average daily usage was under 1 hour in every one of the three months before the month of management, do not bill the management fee.
- Patients within 3 months of starting CPAP are exempt from this rule
- Even then, the notice states that the home treatment materials addition can still be billed
Facility standards for the enhanced management system addition (Note 2)
The facility standards notice (Section 16-7) requires two things.
- Monitoring system: For all non-inpatients receiving CPAP management at the institution who are eligible for fee 2, usage and AHI are regularly monitored with equipment capable of monitoring them
- Management results: Within the most recent 3 months, the share of the total patient-months of CPAP management in which the device was used 4 hours or more on 20 or more days is 40% or higher
How the 40% standard is counted (illustration)
Form 20-12 asks for three figures.
| Item | Content | Example (hypothetical numbers) |
|---|---|---|
| ① | All non-inpatients under CPAP management | 20 patients |
| ② | Total patient-months of CPAP management (last 3 months) | 60 months |
| ③ | Of ②, months with 4+ hours of use on 20+ days | 24 or more meets the standard (24 ÷ 60 = 40%) |
The numbers above are hypothetical, only to show the calculation; the actual judgment uses the form and your last three months of results.
Chart documentation
Interpretive notice item (7) states that for the addition, regardless of whether the management fee is billed, usage and AHI must be monitored for all CPAP-managed patients and the average daily CPAP usage entered in the medical record. Note that monitoring covers patients not billed under this fee as well.
Notification
- Use Form 20-12 of Attachment 2
- The form for the remote monitoring addition is specified separately in the same notice (Attachment 2-2)
Remote monitoring addition (Note 3)
For fee-2 patients on CPAP, when usage and AHI are regularly monitored via information and communication equipment from the month after the previous visit to the month before the current visit, and necessary guidance is given, bill 150 points × the number of months (up to 2) at the visit. Main requirements from interpretive notice item (8):
- With patient consent, create a care plan combining in-person visits and monitoring (including emergency response)
- In the billing month, record the clinical findings from monitoring and any guidance given in the medical record
- Guidance is given by phone or video call; when using communication devices, follow the online care guideline
- The cost of this care is included in the addition
The facility standard requires, when giving guidance by video call, a system for care in line with the online care guideline.
Management via communication devices (Note 4: 218 points)
Under Note 4, when management that would be billed as fee 2 is provided via information and communication devices, bill 218 points instead of 240. The notice specifies:
- Targets are patients meeting condition (c) who are on CPAP with a diagnosis of obstructive sleep apnea
- Do it only after confirming in person that CPAP has improved symptoms such as sleepiness and snoring
- Check the same CPAP management data as in person
- Switch to in-person care promptly if symptoms worsen
- Record the first-visit date and the date of in-person confirmation in the chart and the receipt abstract field
- The facility standard is simply having the notification for care via information and communication devices; no separate notification for Note 4 is needed

Practical checklist
- Do you have a list of CPAP-managed patients and a system to see usage and AHI?
- Can you tally months with 4+ hours on 20+ days against total patient-months for the last 3 months?
- Is average daily CPAP usage recorded in the chart?
- Do you check patients whose average daily use was under 1 hour in all of the previous three months (excluding the first 3 months) before billing fee 2?
- Have you submitted Form 20-12 and confirmed with your regional bureau?
- If using the remote monitoring addition or Note 4, are the care plan and chart items in place?
