Podiatry on Prescription: When Statutory Health Insurance Covers Costs

What lies behind it

The prescription of podiatric services by panel physicians is precisely regulated in Book V of the Social Security Code (SGB V) and in the Medical Remedies Directive (Heilmittel-Richtlinie) of the Federal Joint Committee (Gemeinsamer Bundesausschuss). Under Section 32 of SGB V, individuals with statutory health insurance are entitled to podiatric treatments, provided these are medically necessary to prevent, detect early, or treat secondary damage to the feet. The legislature strictly distinguishes between cosmetic care and podiatric therapy as a medical remedy. Treatment may be prescribed exclusively by general practitioners, diabetologists, neurologists, dermatologists, orthopaedists, or internists.

The basis for billing statutory health insurers is prescription form Muster 13 (standard prescription form). On this document, the physician specifies the precise indication code. In the diagnosis of diabetic foot syndrome, the system distinguishes between the codes DF1 and DF2. DF1 describes pathological callus changes and nail alterations without loss of sensation or angiopathy, whereas DF2 requires the presence of peripheral sensory neuropathy or peripheral arterial disease. At this stage, tissue necrosis threatens without treatment, which is why the protective objective of preventing ulceration is paramount.

In 2020, the legislature expanded the catalogue of benefits to include additional clinical conditions beyond diabetes mellitus. Under indication codes NF1 and NF2, treatment can be prescribed for patients with spinal cord disorders, syringomyelia, spastic spinal paralysis, or hereditary motor and sensory neuropathy. In addition, individuals with occupational disability or chronic illnesses involving traumatic spinal cord injury fall under this code. The prerequisite is always a proven lack of protective sensation or motor dysfunction that renders independent nail and skin care impossible.

Another important indication area is covered by codes UI1 and UI2. UI stands for unguis incarnatus, the ingrown toenail. Since July 2022, orthonyxia, which refers to treatment using nail correction braces, has been anchored as an independent medical remedy in the catalogue of benefits. Statutory health insurance covers the cost of fabricating and fitting custom brace systems, provided the stage of the ingrown nail permits conservative therapy and can be preferred over surgical intervention. Patients with systemic diseases such as scleroderma or chronic polyarthritis also gain access to prescribed treatment if they exhibit severe foot deformities.

Coverage of costs requires that treatment be performed by state-recognised podiatrists. Cosmetic foot care practitioners without official authorization to use the professional title may not bill prescriptions under form Muster 13. Regarding co-payment, the statutory regulation under Section 32(2) in conjunction with Section 61 SGB V applies. Adult patients pay a personal contribution of ten euros per prescription plus ten percent of the total cost of the treatment series. Exempt from this are patients with an exemption certificate from their health insurer, which is issued upon reaching the individual financial burden cap.

Typical signs

Changes in the lower extremities often develop insidiously. Early detection of neuropathic or vascular deficits is crucial in determining whether severe tissue damage can be prevented. In diabetic neuropathy, sensation declines symmetrically, ascending from the tips of the toes. Those affected report numbness, tingling, or a burning sensation, referred to medically as erythromelalgia or paraesthesia. Because the delicate nerve pathways are damaged, patients no longer perceive injuries, chafing from tight footwear, or pressing sock seams.

Impaired skin trophicity represents another warning signal. Due to autonomic nervous system failure, sweat secretion on the foot decreases. The skin becomes cracked, dry, and loses its natural elasticity. Consequently, deep rhagades form, predominantly in the heel area or beneath the metatarsal heads. These skin fissures serve as entry points for bacteria and pose a significant risk of infection when blood supply is inadequate. Excessive callus formation, known as hyperkeratosis, develops at points of highest mechanical stress.

In contrast to neuropathy, peripheral arterial disease is characterized by insufficient arterial blood supply. The feet feel cold and display a pale or livid-cyanotic discolouration. Pulses in the dorsalis pedis artery and the posterior tibial artery are weakened or no longer palpable. Under exertion, cramp-like pain occurs in the calf musculature. When neuropathy and angiopathy combine, the condition is referred to as neuroischaemic foot syndrome, in which susceptibility to infection is extremely high and wound healing is severely delayed.

Regarding nail alterations, an ingrown nail presents with redness, swelling, and tenderness to pressure in the lateral nail fold. When tissue reacts, granulation tissue forms, colloquially referred to as hypergranulation tissue. Subungual hyperkeratosis or haematomas can also form beneath the nails, lifting the nail plate and promoting deformities such as a grypotic nail (onychogryphosis). Rheumatoid patients frequently exhibit severe joint destruction. Hallux valgus, claw toes, and hammer toes alter foot mechanics so severely that painful corns, known as clavi, develop directly over the interphalangeal joints.

Everyday causes

The development of prescribable foot conditions is usually the result of decades of stress or chronic systemic diseases. A lack of knowledge regarding altered physiological conditions leads patients with diabetes or nerve damage to take fateful actions in everyday life. A primary factor in mechanical lesions is ill-fitting footwear. Many people wear shoes that do not match the actual biomechanics of the foot in terms of width and length. Excessively narrow toe boxes compress the toes, encourage ingrowing of the nail edges, and create localized pressure peaks.

Errors in home hygiene and nail care also rank high among triggers. Rounding off the corners of the nail in the lateral groove deprives the nail of guidance. As the nail regrows, the lateral fold presses into the tissue and triggers mechanical inflammation. The use of sharp instruments such as nail scissors, clippers, or callus rasps carries an immense risk of injury for patients with neuropathy. Because warning pain is absent, affected individuals not infrequently cut into vascularised dermal tissue without noticing it immediately.

Inappropriate footbaths are equally critical. Excessive soaking times soften the stratum corneum, causing the skin's protective barrier against microorganisms to collapse. If the water is set too hot, second-degree burns threaten, as temperature perception is severely impaired in neuropathic foot syndromes. The use of over-the-counter corn plasters containing salicylic acid also regularly leads to chemical burns of the surrounding tissue in high-risk patients.

Biomechanical deformities continuously increase stress. Splayfoot, flatfoot, or fallen arches shift the load line of the lower extremity. Body weight no longer presses evenly on the heel, the first metatarsal head, and the fifth metatarsal head, but concentrates on the middle metatarsals. Without podiatric removal of the resulting keratoses and without orthotic offloading, tissue haemorrhages and severe ulcers form beneath the callosities.

When medical evaluation is necessary

Podiatric treatment does not replace medical diagnosis and therapy by a specialist. Affected individuals must learn to interpret warning signs early and consult a physician immediately. Emergency medical evaluation is mandatory as soon as open wounds, blisters, or visible skin discolourations appear. A blackish discolouration indicates gangrene, whereas widespread redness with local heat can signal erysipelas or phlegmon.

Purulent discharge, foul-smelling secretions from the nail fold, or a sudden increase in swelling also require immediate evaluation by a diabetologist, dermatologist, or surgeon. Wound infections in patients with reduced arterial blood flow spread within hours and, in the worst case, can trigger a sepsis-inducing cascade. Adjusting antibiotic therapy or performing surgical debridement cannot be delayed in such cases.

Sudden pain in the foot or lower leg accompanied by paleness and coldness of the extremity points to acute arterial occlusion. This represents a vascular surgical emergency. However, painless, seemingly harmless redness in diabetic patients also requires clarification. Behind this may lie Charcot arthropathy, a destructive disease of the bones and joints of the foot, which in its acute stage requires immediate offloading in a cast or specialized boot to prevent the collapse of the foot skeleton.

Before starting any initial podiatric treatment under prescription, the medical diagnosis must be established. The attending physician decides on the necessity of the measure and checks for potential contraindications. Regular follow-up examinations in the prescribing physician's practice ensure that concomitant conditions, such as poorly controlled blood glucose levels or progressive peripheral arterial disease, are identified early and therapeutically adjusted.

What podiatric treatment can achieve

Podiatric therapy in the practice follows clear, medically sound standards. Before actual treatment begins, a detailed medical history and clinical assessment are conducted. The podiatrist examines the skin for lesions, assesses pulse status, and evaluates surface and deep sensitivity levels. A Rydel-Seiffer 128 Hz tuning fork is used to test vibration perception. Pain and pressure sensitivity are evaluated using a certified Semmes-Weinstein monofilament with a testing force of ten grams. These measurements seamlessly document the course of the disease.

The actual podologische Komplexbehandlung (comprehensive podiatric treatment) combines dermatological and nail therapy interventions. The scope of services includes the following core diagnostic and therapeutic measures:

• Atraumatic removal of hyperkeratosis and calluses using scalpel and shaver techniques while sparing healthy tissue
• Gentle cutting, grinding, and cleaning of thickened, mycotic, or deformed toenails using rotating diamond and carbide cutters
• Treatment of ingrown nails including probing of the lateral fold and application of offloading tampons
• Custom fitting and installation of individual nail correction braces for unguis incarnatus to achieve permanent correction of nail curvature
• Fabrication of custom pressure protection elements made from medical-grade silicone to relieve corns and toe deformities

Risk minimization is the central focus in treating diabetic foot syndrome. Sterile instruments reprocessed according to the guidelines of the Robert Koch Institute are used. All rotary instruments operate with precisely controlled rotational speeds and water cooling to prevent thermal damage to the nail bed or skin. Any removal of calloused tissue is performed layer by layer. Exactly as much cornified material is left behind as the foot requires as physiological protection against mechanical pressure.

Various systems are used in orthonyxia (brace therapy), which is prescribable as a statutory health insurance benefit. The range extends from one-piece and three-piece spring steel wire braces, such as the Ross-Fraser or 3-piece brace, to adhesive and combination braces. The principle is based on continuous tension. The elasticity of the wire gently lifts the lateral nail edges out of the inflamed fold. This leads to immediate pressure relief and enables pain-free healing of the inflammation. The treatment period for brace therapy usually spans six to twelve months, as the nail must regrow completely pain-free.

The standard treatment duration of a podologische Komplexbehandlung (comprehensive podiatric treatment) averages between 30 and 45 minutes. Depending on the prescribed quantity and findings, sessions take place at intervals of four to six weeks. This rhythm is optimally aligned with the natural regeneration of the epidermis and physiological nail growth.

What you can do yourself

At-home self-care forms the most important supplement to professional podiatric therapy. Patients with sensory impairments must firmly integrate daily inspection routines into their schedule. Systematic examination of the feet requires good lighting conditions. An unbreakable hand mirror or a telescopic mirror placed on the floor helps to inspect the heels and soles of the feet closely. Alternatively, relatives can be asked for assistance.

Clear rules must be observed during daily hygiene to avoid damaging fragile tissue. The following steps should be firmly established:

1. Wash your feet daily in lukewarm water, ensuring the bathing duration does not exceed three minutes.
2. Always check the water temperature with a bath thermometer or your elbow; a maximum of 37 degrees Celsius is permitted.
3. Carefully dry the skin, especially the spaces between the toes, by gently patting without vigorous rubbing.
4. Subsequently apply a nourishing lotion to the skin, preferably one containing five to ten percent urea.
5. Consistently avoid applying cream between the toes to prevent moisture accumulation and fungal infections.

The choice of socks and footwear also demands attention. Socks should be made of natural cotton or wool and free from restrictive elastic bands. Bulky seams over the toes must be avoided, or the socks should be worn inside out. Before putting on shoes, the inside must be checked thoroughly with your hand for foreign bodies, such as small stones, protruding seams, or folded insoles.

Walking barefoot carries considerable risks for high-risk patients. Broken glass, small stones, or scorching patio slabs in summer quickly lead to severe lesions that are noticed late due to a lack of pain perception. Sturdy slippers with a closed toe cap provide the necessary protection at home.

Common mistakes

In clinical practice, the same typical operational errors recur repeatedly, leading to complications. A widespread misconception is attempting to self-correct ingrown nails using wedge cuts or deeply trimming the nail edges. By removing the corner of the nail, the skin of the fold contracts. As the nail regrows, its usually sharp edge digs deeper into the soft tissue with every step. This results in chronic granulation tissue and makes lengthy brace treatment necessary.

Another serious mistake is the use of improper tools. Pumice stones, rasps, callus shavers, or even razor blades have no place in the hands of high-risk patients. Blades easily slip on dry skin and create incised wounds that quickly become infected. Equally dangerous is the use of corn plasters or tinctures containing highly concentrated acids. These agents do not distinguish between dead calloused tissue and healthy skin. They etch deeply into the tissue and often leave behind chemical burns that are difficult to heal.

Delays in submitting the prescription for medical remedies represent an administrative source of error. A prescription Muster 13 (standard prescription form) issued by a physician loses its validity if treatment is not commenced within 28 calendar days of the issue date. If the physician has checked urgent treatment need on the form, this period is shortened to 14 calendar days. If the patient misses this period, health insurance providers will no longer accept the prescription, and a new prescription must be issued by the physician's practice.

Finally, many patients underestimate the importance of correct deadlines for co-payments or follow-up prescriptions. After completing a treatment series, usually consisting of four to six sessions, the physician must evaluate success before a follow-up prescription can be issued. Arbitrarily skipping appointments results in intervals between treatments becoming too long. Consequently, the skin calluses heavily again, or the fitted nail brace loses its optimal tensile effect.

Study findings and scientific context

The evidence supporting the effectiveness of preventive and therapeutic podiatric measures is extensively documented in medical literature. The National Care Guideline for Type 2 Diabetes highlights that regular professional foot examinations and podiatric treatments in high-risk patients can reduce the rate of ulcerations and major amputations by up to 60 percent [1]. Timely removal of hyperkeratosis demonstrably reduces local peak pressure beneath the metatarsal heads by more than 30 percent, which is considered a decisive factor in the primary prevention of tissue necrosis [2].

Studies on the treatment of unguis incarnatus demonstrate the equivalence of conservative brace therapy compared to surgical interventions, such as wedge excision or Vandenbos procedures, in stage 1 and 2 disease [3]. While surgical procedures are often associated with longer downtime and a recurrence rate of up to 20 percent, orthonyxia shows an excellent success rate with minimal tissue stress. The integration of brace therapy into the statutory health insurance remedy catalogue in 2022 is directly based on these scientific findings.

Regarding treatment frequency, clinical studies show that an interval of four to six weeks in patients with diabetic neuropathy offers the highest cost-effectiveness and quality of care [4]. Longer treatment intervals lead to a significant increase in skin fissures and subungual haematomas. The guidelines of the German Diabetes Society (Deutsche Diabetes Gesellschaft) emphasize the importance of interdisciplinary cooperation between general practitioners, diabetologists, podiatrists, and orthopaedic shoe technicians as the gold standard in limb preservation [5].
