Podiatry Coding & Billing Alert

Gout:

Other Coding Options Depend On Underlying Cause

Before you code for gout, take note whether your podiatrist has documented gouty arthropathy, acute gout, or chronic gout and whether any lab tests were ordered to establish the presence or absence of tophus/tophi (deposits of urate crystals in the skin surrounding the joints).

Further, though it is unlikely that he will have ordered lab tests to establish origin of gout; the chances are that he will have referred to the primary physician’s records. To code lead-induced and drug-induced gout your options are:

  • M1A.17 — Lead-induced chronic gout, ankle and foot
  • M1A.172 — Lead-induced chronic gout, left ankle and foot
  • M1A.171 — Lead-induced chronic gout, right ankle and foot
  • M1A.179 — Lead-induced chronic gout, unspecified ankle and foot
  • M1A.27 — Drug-induced chronic gout, ankle and foot
  • M1A.272 — Drug-induced chronic gout, left ankle and foot
  • M1A.271 — Drug-induced chronic gout, right ankle and foot
  • M1A.2711 — Drug-induced chronic gout, right ankle and foot, with tophus (tophi)
  • M1A.2710 — Drug-induced chronic gout, right ankle and foot, without tophus (tophi).

When the gout is due to renal impairment, your coding options are:

  • M1A.37 — Chronic gout due to renal impairment, ankle and foot
  • M1A.372 — Chronic gout due to renal impairment, left ankle and foot
  • M1A.3721 — Chronic gout due to renal impairment, left ankle and foot, with tophus (tophi)
  • M1A.3720 — Chronic gout due to renal impairment, left ankle and foot, without tophus (tophi)
  • M1A.371 — Chronic gout due to renal impairment, right ankle and foot
  • M1A.3711 — Chronic gout due to renal impairment, right ankle and foot, with tophus (tophi)
  • M1A.3710 — Chronic gout due to renal impairment, right ankle and foot, without tophus (tophi)
  • M1A.379 — Chronic gout due to renal impairment, unspecified ankle and foot
  • M1A.3791 — Chronic gout due to renal impairment, unspecified ankle and foot, with tophus (tophi)
  • M1A.3790 — Chronic gout due to renal impairment, unspecified ankle and foot, without tophus (tophi).

When the gout is the secondary ailment, you would code it as:

  • M1A.471 — Other secondary chronic gout, right ankle and foot
  • M1A.4711 — Other secondary chronic gout, right ankle and foot, with tophus (tophi)
  • M1A.4710 — Other secondary chronic gout, right ankle and foot, without tophus (tophi)
  • M1A.479 — Other secondary chronic gout, unspecified ankle and foot
  • M1A.4791 — Other secondary chronic gout, unspecified ankle and foot, with tophus (tophi)
  • M1A.4790 — Other secondary chronic gout, unspecified ankle and foot, without tophus (tophi).
