Podiatry Coding & Billing Alert

ICD-10 Update:

Congenital Pes Cavus, Enthesopathy Diagnoses Top Your New Podiatry ICD-10 Codes

Report new code L89.506 for pressure-induced deep tissue damage of an unspecified ankle.

CMS recently published its list of the new ICD-10 2020 codes, but they won’t go into effect until Oct. 1, 2019. Read on to check out how these new codes and revisions will impact your podiatry practice’s bottom line.

Dig Into Shiny, New Pressure Ulcer Codes

If you report ulcers in your podiatry practice, you might recall that the last couple of years have brought new and revised codes to this category. ICD-10 2020 will be no exception, and you will gain the following new codes:

  • L89.506 (Pressure-induced deep tissue damage of unspecified ankle)
  • L89.516 (… of right ankle)
  • L89.526 (… of left ankle)
  • L89.606 (… of unspecified heel)
  • L89.616 (… of right heel)
  • L89.626 (… of left heel).

These new codes will be indexed between the codes that identify stage four pressure ulcers and unspecified stage pressure ulcers. For example, look at where new code L89.616 will fall in the existing lineup of pressure ulcer codes:

  • L89.614 (Pressure ulcer of right heel, stage 4)
  • New code: L89.616 (Pressure-induced deep tissue damage of right heel)
  • L89.619 (Pressure ulcer of right heel, unspecified stage).

The new pressure ulcer codes are more specific and will better define the exact areas of the ulcerations, explains Arnold Beresh, DPM, CPC, CSFAC, in West Bloomfield, Michigan.

Don’t Overlook These Enthesopathy Revisions

Revisions: You’ll see some revisions to current enthesopathy codes M77.50-M77.52. All of these codes will add the word “ankle” to the descriptor. Take a look at the revisions (emphasis added):

  • M77.50 (Other enthesopathy of unspecified foot and ankle)
  • M77.51 (… of right foot and ankle)
  • M77.52 (… of left foot and ankle).

Other enthesopathy defined: “Other enthesopathy” refers to a disorder that affects the site where ligaments, tendons, or muscles attach to the joint or bone — the result of an inflammatory rheumatic or nonrheumatic disease. This code represents an enthesopathy not specifically named under any other ICD-10 codes.

Clarify New Congenital Diagnoses

You’ll also get these new codes to choose from when reporting congenital conditions:

  • Q66.00 (Congenital talipes equinovarus, unspecified foot)-Q66.02 (… left foot)
  • Q66.10 (Congenital talipes calcaneovarus, unspecified foot)-Q66.12 (… left foot)
  • Q66.211 (Congenital metatarsus primus varus, right foot)-Q66.219 (… unspecified foot)
  • Q66.221 (Congenital metatarsus adductus, right foot)-Q66.229 (… unspecified foot)
  • Q66.30 (Other congenital varus deformities of feet, unspecified foot)-Q66.32 (… left foot)
  • Q66.40 (Congenital talipes calcaneovalgus, unspecified foot)-Q66.42 (… left foot)
  • Q66.70 Congenital pes cavus, unspecified foot)-Q66.72 (… left foot)
  • Q66.90 (Congenital deformity of feet, unspecified, unspecified foot)-Q66.92 (… unspecified, left foot).

Don’t miss: If you look at all of the above codes, you will see that ICD-10 2020 adds a fifth character to the original fourth character base code for added specificity.

For example, you currently report Q66.7 (Congenital pes cavus) for congenital pes cavus. But starting in October 2019, you will be able to specify whether the pes cavus affected an unspecified foot (Q66.70); the right foot (Q66.71); or the left foot (Q66.72).

Navigate T and Z-Code Additions

ICD-10 2020 will also add a few new T-codes. For example, category T50.9- (Poisoning by, adverse effect of and underdosing of other and unspecified drugs, medicaments and biological substances) will gain the following codes:

  • T50.91- (Poisoning by, adverse effect of and underdosing of multiple unspecified drugs, medicaments and biological substances)
  • T50.911 (Poisoning by multiple unspecified drugs, medicaments and biological substances, accidental (unintentional))
  • T50.912 (… intentional self-harm)
  • T50.913 (… assault)
  • T50.914 (… undetermined)
  • T50.915 (Adverse effect of multiple unspecified drugs, medicaments and biological substances)
  • T50.916 (Underdosing of multiple unspecified drugs, medicaments and biological substances).

You will also see a few new Z-codes, which represent factors influencing health status and contact with health services. They are as follows:

  • Z71.84 (Encounter for health counseling related to travel)
  • Z86.006 (Personal history of melanoma in-situ)
  • Z86.007 (Personal history of in-situ neoplasm of skin).
