Addressing the 'Diagnostic Letter Barrier' in Disability Pension Applications | Nationwide 'Doctor Navi Map' Launched, Featuring Over 2,500 Medical Institutions

Social Insurance and Labor Consultant Firm Zenkoku Shogai Nenkin Partners (Chiyoda City, Tokyo; Representative: Takeyoshi Miyazato), which specializes in disability pension applications for depression and has supported over 2,500 individuals, has launched a new service called 'Doctor Navi Map'—a searchable directory of medical institutions with proven experience in issuing diagnostic letters for disability pensions.

A diagnostic letter written by a physician is essential for applying for a disability pension. However, many applicants are unable to proceed because their primary care physicians decline, citing reasons such as 'I don’t handle this' or 'I can’t write such letters.'

'Doctor Navi Map' features over 2,500 medical institutions nationwide that Zenkoku Shogai Nenkin Partners has confirmed, through its pension application support services, have actual experience both in issuing diagnostic letters and in successful disability pension awards. Users can search by prefecture or hospital name.

The 'Diagnostic Letter Barrier' Blocking Disability Pension Applications

Mental health conditions such as depression, bipolar disorder, and schizophrenia may qualify for disability pensions if certain criteria are met.

However, according to a report published by the Ministry of Health, Labour and Welfare in June 2025, the denial rate for new mental disability pension applications in FY2024 was 12.1%, a significant increase from the previous year’s 6.4%, indicating a tightening of review standards.

In this context, the importance of an accurate diagnostic letter that clearly conveys the applicant’s symptoms and daily life challenges has become greater than ever. Yet, many individuals contacting our firm report being turned down by their physicians when requesting the required diagnostic letter, with common reasons including:

'I’ve never written a disability pension diagnostic letter before.'

'I don’t handle pension-related letters.'

'Our clinic doesn’t issue these letters.'

'If you’re working, you probably don’t qualify.'

'I’m not familiar with the disability pension system.'

Without a diagnostic letter, applicants cannot complete their application documents—leading some to abandon their applications despite potentially qualifying for benefits.

Significant Anxiety Around Transferring to Another Physician

When a current physician refuses to issue a diagnostic letter, transferring to another medical institution may be an option. However, many hesitate due to concerns such as: 'What if the next hospital also refuses?', 'I don’t know which clinics are willing to help?', or 'Could transferring negatively affect my application?'

A disability pension diagnostic letter is a crucial document that conveys not only the diagnosis but also the applicant’s daily living capacity, employment status, and symptom progression. Access to a medical institution familiar with the system is therefore critical to a successful application.

'Doctor Navi Map' is a free, nationwide search service for medical institutions with experience in issuing disability pension diagnostic letters.

Five Key Points to Keep in Mind When Requesting a Diagnostic Letter

Alongside 'Doctor Navi Map,' Zenkoku Shogai Nenkin Partners also provides guidance on how to approach physicians about diagnostic letters. As these letters significantly influence the outcome of the review, the way they are requested can affect whether symptoms and real-life challenges are accurately conveyed.

1. Clearly describe specific difficulties in daily life

Physicians may not fully grasp daily challenges within the limited time of a consultation. Preparing notes on difficulties with household tasks, shopping, social interactions, sleep, etc., can help ensure these issues are reflected in the diagnostic letter.

2. Honestly share your average, overall condition

Responding 'I’m fine' during a consultation may lead the physician to perceive your condition as milder than it actually is. It’s important to honestly convey fluctuations between good and bad days and your average level of impairment.

3. Understand that 'working' does not automatically disqualify you

Even if employed, individuals may still qualify for a disability pension if they face significant work challenges or rely on accommodations to maintain employment. Clearly communicating the reality of your work situation is crucial.

4. Prepare information on symptom progression and initial diagnosis date

In addition to current symptoms, the review process considers past treatment history, symptom changes, and the initial diagnosis date. Preparing a chronological record in advance can streamline communication with your physician and document preparation.

5. Make the request thoughtfully, with consideration for the physician’s workload

Writing diagnostic letters is time-consuming for physicians. Providing organized information and expressing gratitude increases the likelihood of cooperation. These efforts are not about persuading the physician to write favorably, but about ensuring an accurate reflection of your condition and daily life.

Comment from Takeyoshi Miyazato, Representative, Zenkoku Shogai Nenkin Partners

'We have received numerous inquiries from individuals seeking disability pensions who say, 'My doctor refused to write the diagnostic letter,' or 'I don’t know which hospital I can consult.' The disability pension system is vital for supporting those struggling in daily life. Yet, the reality is that many are unable to apply simply because they cannot obtain a diagnostic letter.

To address this, we have launched 'Doctor Navi Map' as a reference tool to help individuals find medical institutions experienced in writing these letters, based on our past support cases. We believe that knowing about institutions with prior experience can help those in distress take their next step forward.

Going forward, we will continue updating and expanding the database, while offering comprehensive support—from eligibility checks and diagnostic letter requests to application preparation—for individuals applying for disability pensions due to depression or other mental health conditions. We remain committed to providing information and support so that no one abandons their application at the diagnostic letter stage.'
