Plantar Fasciitis ICD-10 Code: Complete Billing Guide (2027)

On October 1, 2026, the ICD 10 code most clinics had used for plantar fasciitis for eleven years stopped being billable. M72.2 became a non-billable parent code for plantar fascial fibromatosis, and plantar fasciitis moved to a subcategory of its own, as the 2027 ICD-10-CM tabular listing now shows on their website.

The ICD-10-CM code for plantar fasciitis is M67.A01 for the right foot, M67.A02 for the left foot and M67.A09 when the side is not recorded on the document. These codes apply to dates of service taken on or after October 1, 2026. Claims for earlier dates still use M72.2 as of now.

That is the pattern with this diagnosis. The condition did not change; the classification did. Practices that kept M72.2 in templates, favorites lists or active plans of care are now sending invalid codes, and the new codes add a requirement which the old one never had: laterality. This guide explains the change, how to code every plantar fasciitis scenario while billing this service that goes with it.

What Is the ICD-10 Code for Plantar Fasciitis?

Plantar fasciitis is coded in subcategory M67.A, Plantar fasciitis, under category M67, Other disorders of synovium and tendon. The billable codes are M67.A01 (plantar fasciitis, right foot), M67.A02 (plantar fasciitis, left foot) and M67.A09 (plantar fasciitis, unspecified foot). The code M72.8, Other fibroblastic disorders, now carries an Excludes1 note pointing plantar fasciitis to M67.A0-, according to published ICD10Data.

Why Did the Plantar Fasciitis Code Change in FY 2027?

Since ICD-10-CM began in October 2015, the Alphabetic Index sent plantar fasciitis to M72.2, Plantar fascial fibromatosis, a fibrotic disorder of the same tissue but a different condition. The FY 2027 update separated them. M72.2 became a parent code for plantar fascial fibromatosis with three laterality codes, and plantar fasciitis received the new M67.A subcategory. The NCHS conversion table maps all six new codes back to M72.2, as Orion’s summary of the FY 2027 changes notes.

The financial year 2027 code set applies to all HIPAA covered transactions, not only Medicare and Medicaid, so every payer moved to the new codes on the same day. The code follows the date of service and a visit on September 30, 2026 uses M72.2, and a visit on October 1, 2026 uses M67.A0-, even inside the same episode of care.

What Is the ICD-10 Code for Bilateral Plantar Fasciitis?

There is no single bilateral code for plantar fasciitis. When both feet are affected, report both M67.A01 and M67.A02. ICD-10-CM guidelines direct coders to assign separate codes for the right and left sides when a condition is bilateral and the classification has no bilateral code.

What Is the ICD-10 Code for Plantar Fasciitis, Unspecified?

M67.A09, plantar fasciitis, unspecified foot, is used when the record does not state which foot is affected. It is billable, and plantar fasciitis NOS falls here. But it should be rare: the side is almost always known at the visit, and many payers question unspecified laterality on claims for treatments such as injections or orthotics. If the note is silent on the side, query the provider.

Is There an ICD-10 Code for Chronic Plantar Fasciitis?

No. ICD-10-CM does not separate acute and chronic plantar fasciitis, so chronic plantar fasciitis uses the same M67.A0- codes. Chronicity still matters in the record. Payers often require documentation of how long symptoms have lasted and which conservative treatments failed before they cover procedures such as extracorporeal shock wave therapy or surgery.

What Is Plantar Fasciitis?

Plantar fasciitis is pain and irritation of the plantar fascia, the thick band of tissue that runs along the bottom of the foot from the heel bone to the toes. It typically causes sharp heel pain with the first steps in the morning or after rest. StatPearls describes it as the most common cause of heel pain in outpatient care, as its clinical overview explains. Risk factors include running and prolonged standing, obesity, tight calf muscles and flat or high-arched feet.

What does plantar fasciitis mean?

The term breaks down into plantar (the sole of the foot), fascia (a band of connective tissue) and -itis (inflammation). Research suggests the condition is often degenerative rather than purely inflammatory, which is why some clinicians prefer the term plantar fasciopathy.

What Is Another Name for Plantar Fasciitis?

Plantar fasciitis is also called plantar fasciopathy, plantar fasciosis and, informally, policeman’s heel or jogger’s heel. For coding, the term in the record matters less than the condition it describes: when the provider documents plantar fasciitis by any of these names, it codes to M67.A0- with the right laterality. If the documentation is unclear, check the Alphabetic Index or query the provider.

What’s the Difference Between Plantar Fascia and Plantar Fasciitis?

The plantar fascia is the anatomy: the band of tissue that supports the arch of the foot. Plantar fasciitis is the condition: pain and tissue changes in that band. A second condition of the same tissue, plantar fascial fibromatosis or Ledderhose disease, involves firm nodules in the fascia and now has its own codes.

Which Related Diagnosis Codes Are Used With Heel Pain?

Plantar fasciitis is often documented with, or confused with, other heel and foot conditions. Code each one only when the provider documents it.

What CPT Codes Are Billed With Plantar Fasciitis?

Treatment for plantar fasciitis ranges from office visits and therapy to injections and, rarely, surgery. These are the codes most often paired with M67.A0-:

What Documentation Supports a Plantar Fasciitis Claim?

What Are the Most Common Plantar Fasciitis Billing Errors?

An invalid or unsupported diagnosis usually shows up as CARC 16 or CARC 11 on the remittance, as our guide to common denial codes in medical billing explains.

How Should Practices Update Plantar Fasciitis Claims After October 1, 2026?

The remap is small, but stale codes hide in predictable places. Work through each one:

How Can iSolve RCM Help With Plantar Fasciitis Billing?

iSolve RCM updates diagnosis code mappings when the code set changes, so podiatry, orthopedic and physical therapy claims carry the right plantar fasciitis code and laterality from the first visit. Our certified medical coding team reviews injections, orthotics and procedures against payer policy, and our medical billing audit catches code set errors before payers do, starting at 2.99% of monthly collections.
