Indications and Limitations of Coverage

Routine Foot Care (S0390)
Routine foot care is generally not covered. A participating, preferred, or network provider can bill the member for these services when they are denied. However, certain groups do provide coverage for routine foot care. Specific coverage information for each group is identified in the benefits schedule.

When a benefit, routine foot care is covered according to the guidelines identified in this policy.

Professional treatment of corns, callouses, clavus, tyloma or tylomata, plantar keratosis, hyperkeratosis and keratotic lesions, bunions (except capsular or bone surgery thereof), and nails (except surgery for ingrown nails and/or debridement of symptomatic, hypertrophic nails) is reimbursable only if the patient is being treated for one of the following diagnoses:

Amyotrophic Lateral Sclerosis (ALS) (335.20)
Arteriosclerosis obliterans (A.S.O., arteriosclerosis of the extremities, occlusive peripheral arteriosclerosis) (440.20-440.24, 440.29, 440.9)

Whirlpool treatment, procedure code 97022, performed before routine foot care to soften the nails or skin is not eligible for separate reimbursement.

Debridement of Mycotic Nails (S0390)
Debridement of mycotic nails is considered routine foot care (S0390). It is not a covered service unless otherwise identified in the benefits schedule. However, debridement of symptomatic non-mycotic hypertrophic nails is considered a covered service.

Debridement of Non-mycotic Hypertrophic Nails (11720, 11721)
Debridement of symptomatic (non-mycotic) hypertrophic nails should be processed for payment under the following codes:

11720 - Debridement of nail(s) by any method(s); one to five
11721 - six or more

Payment for debridement of hypertrophic nails is limited to once per patient every 60 days. More frequent debridements are not medically necessary.

Fungal (mycotic) infections of the feet and toenails may require professional medical care outside the scope of routine foot care. Medical treatment of a fungal infection of the feet should be reported with the appropriate visit code.

Whirlpool treatment, procedure code 97022, performed prior to debridement of mycotic/hypertrophic nails to soften the nails or skin is not eligible for separate reimbursement.

Coverage for routine foot care is determined according to individual or group customer benefits.

Description

Routine Foot Care (S0390)
Routine foot care includes the treatment of corns, callouses, clavus, tyloma or tylomata, plantar keratosis, hyperkeratosis and keratotic lesions, bunions (except capsular or bone surgery thereof), and nails (except surgery for ingrown nails and/or debridement of symptomatic, hypertrophic nails). Treatment of these conditions may pose a hazard when performed by a non-professional person on patients with a systemic condition that has resulted in severe circulatory embarrassment or areas of desensitization in the legs or feet.

Debridement of Mycotic Nails (S0390)
Routine foot care also includes the debridement of mycotic nails, S0390. This service is the temporary reduction in the size or girth of an abnormal nail plate, short of avulsion. It is performed most commonly without anesthesia to: (1) relieve pain; (2) treat infection (bacterial, fungal, or viral); (3) temporarily remove an anatomic deformity such as onychauxis (thickened nail), or certain types of onychocryptosis (ingrown nail); (4) expose subungual conditions for the purpose of treatment as well as diagnosis (biopsy, culture, etc.); (5) prevent further problems, such as subungual ulceration in an insensate patient with onychauxis.


NOTE:
This policy is designed to address medical guidelines that are appropriate for the majority of individuals with a particular disease, illness, or condition. Each person's unique clinical circumstances may warrant individual consideration, based on review of applicable medical records.

This policy is designed to address medical guidelines that are appropriate for the majority of individuals with a particular disease, illness, or condition. Each person's unique clinical circumstances may warrant individual consideration, based on review of applicable medical records.

Medical policies are designed to supplement the terms of a member's contract. The member's contract defines the benefits available; therefore, medical policies should not be construed as overriding specific contract language. In the event of conflict, the contract shall govern.

Medical policies do not constitute medical advice, nor the practice of medicine. Rather, such policies are intended only to establish general guidelines for coverage and reimbursement under Mountain State Blue Cross Blue Shield plans. Application of a medical policy to determine coverage in an individual instance is not intended and shall not be construed to supercede the professional judgment of a treating provider. In all situations, the treating provider must use his/her professional judgment to provide care he/she believes to be in the best interest of the patient, and the provider and patient remain responsible for all treatment decisions.

Mountain State Blue Cross Blue Shield (MSBCBS) retains the right to review and update its medical policy guidelines at its sole discretion. These guidelines are the proprietary information of MSBCBS. Any sale, copying or dissemination of the medical policies is prohibited; however, limited copying of medical policies is permitted for individual use.
